unavailable, move resource allocattion from kms_init directly to the
probe callback. While we are at it, replace irq_of_parse_and_map() with

This also drops devm_iounmap() calls. It is too early to have them
_dpu_kms_hw_destroy() (or it will break if for some reason DPU device is
rebound into the composite device) and it doesn't make sense to have
them in dpu_dev_remove (as everything will be torn down by the devres
anyway after the device is unbound from the driver).

75cb60d4f5 drm/msm/a6xx: Fix unknown speedbin case
When opp-supported-hw is present under an OPP node, but no form of
opp_set_supported_hw() has been called, that OPP is ignored by the API
and marked as unsupported.

Before Commit c928a05e44 ("drm/msm/adreno: Move speedbin mapping to
device table"), an unknown speedbin would result in marking all OPPs
as available, but it's better to avoid potentially overclocking the
silicon - the GMU will simply refuse to power up the chip.

Currently, the Adreno speedbin code does just that (AND returns an
invalid error, (int)UINT_MAX). Fix that by defaulting to speedbin 0
(which is conveniently always bound to fuseval == 0).

b77532803d drm/msm/a6xx: Poll for GBIF unhalt status in hw_init
Some GPUs - particularly A7xx ones - are really really stubborn and
sometimes take a longer-than-expected time to finish unhalting GBIF.

Note that this is not caused by the request a few lines above.

Poll for the unhalt ack to make sure we're not trying to write bits to
an essentially dead GPU that can't receive data on its end of the bus.
Failing to do this will result in inexplicable GMU timeouts or worse.

This is a rather ugly hack which introduces a whole lot of latency.

af66706acc drm/msm/a6xx: Add skeleton A7xx support
A7xx GPUs are - from kernel's POV anyway - basically another generation
of A6xx. They build upon the A650/A660_family advancements, skipping some
writes (presumably more values are preset correctly on reset), adding
some new ones and changing others.

One notable difference is the introduction of a second shadow, called BV.
To handle this with the current code, allocate it right after the current
RPTR shadow.

BV handling and .submit are mostly based on Jonathan Marek's work.

All A7xx GPUs are assumed to have a GMU.
A702 is not an A7xx-class GPU, it's a weird forked A610.

a251c9d8e3 drm/msm/dp: skip validity check for DP CTS EDID checksum
The DP CTS test for EDID last block checksum expects the checksum for

For the most part (*), the EDIDs returned by drm_get_edid() will be

completely invalid EDIDs. See commit 7948fe12d4 ("drm/msm/dp: return
correct edid checksum after corrupted edid checksum read").

This lets us remove one user of drm_edid_block_valid() with hopes the
function can be removed altogether in the future.

(*) drm_get_edid() ignores checksum errors on CTA extensions.

of DSC for DSI being set during runtime in the future.

ab483e3adc drm/msm/dsi: skip the wait for video mode done if not applicable
dsi_wait4video_done() API waits for the DSI video mode engine to
become idle so that we can transmit the DCS commands in the
beginning of BLLP. However, with the current sequence, the MDP
timing engine is turned on after the panel's pre_enable() callback
which can send out the DCS commands needed to power up the panel.

During those cases, this API will always timeout and print out the
error spam leading to long bootup times and log flooding.

Fix this by checking if the DSI video engine was actually busy before
waiting for it to become idle otherwise this is a redundant wait.

changes in v2:
	- move the reg read below the video mode check
	- minor fixes in commit text

0c1a2e69bc drm/msm/dp: do not reinitialize phy unless retry during link training
DP PHY re-initialization done using dp_ctrl_reinitialize_mainlink() will
cause PLL unlocked initially and then PLL gets locked at the end of
initialization. PLL_UNLOCKED interrupt will fire during this time if the
interrupt mask is enabled.

However currently DP driver link training implementation incorrectly
re-initializes PHY unconditionally during link training as the PHY was
already configured in dp_ctrl_enable_mainlink_clocks().

Fix this by re-initializing the PHY only if the previous link training
failed.

drm/msm: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert the msm drm drivers from always returning zero in the
remove callback to the void returning variant.

This patchset changes the API used by the MM to set up page table entries.
The four APIs are:

    set_ptes(mm, addr, ptep, pte, nr)
    update_mmu_cache_range(vma, addr, ptep, nr)
    flush_dcache_folio(folio) 
    flush_icache_pages(vma, page, nr)

flush_dcache_folio() isn't technically new, but no architecture
implemented it, so I've done that for them.  The old APIs remain around
but are mostly implemented by calling the new interfaces.

The new APIs are based around setting up N page table entries at once. 
The N entries belong to the same PMD, the same folio and the same VMA, so
ptep++ is a legitimate operation, and locking is taken care of for you. 
Some architectures can do a better job of it than just a loop, but I have
hesitated to make too deep a change to architectures I don't understand
well.

One thing I have changed in every architecture is that PG_arch_1 is now a
per-folio bit instead of a per-page bit when used for dcache clean/dirty
tracking.  This was something that would have to happen eventually, and it
makes sense to do it now rather than iterate over every page involved in a
cache flush and figure out if it needs to happen.

The point of all this is better performance, and Fengwei Yin has measured
improvement on x86.  I suspect you'll see improvement on your architecture
too.  Try the new will-it-scale test mentioned here:
https://lore.kernel.org/linux-mm/20230206140639.538867-5-fengwei.yin@intel.com/
You'll need to run it on an XFS filesystem and have
CONFIG_TRANSPARENT_HUGEPAGE set.

This patchset is the basis for much of the anonymous large folio work
being done by Ryan, so it's received quite a lot of testing over the last
few months.


This patch (of 38):

Determine if a value lies within a range more efficiently (subtraction +
comparison vs two comparisons and an AND).  It also has useful (under some
circumstances) behaviour if the range exceeds the maximum value of the
type.  Convert all the conflicting definitions of in_range() within the
kernel; some can use the generic definition while others need their own
definition.

7391c282ba drm/msm: Remove vma use tracking
This was not strictly necessary, as page unpinning (ie. shrinker) only
cares about the resv.  It did give us some extra sanity checking for
userspace controlled iova, and was useful to catch issues on kernel and
userspace side when enabling userspace iova.  But if userspace screws
this up, it just corrupts it's own gpu buffers and/or gets iova faults.
So we can just let userspace shoot it's own foot and drop the extra per-
buffer SUBMIT overhead.

db07ce5da8 drm/msm/a2xx: Call adreno_gpu_init() earlier
The adreno_is_a20x() and adreno_is_a225() functions rely on the
GPU revision, but such information is retrieved inside adreno_gpu_init(),
which is called afterwards.

Fix this problem by caling adreno_gpu_init() earlier, so that
the GPU information revision is available when adreno_is_a20x()
and adreno_is_a225() run.

Tested on a imx53-qsb board.

is identical to QCM2290, whose config struct can trivially be reused.

To make this possible pass the struct dpu_mdss_version to

b173a7dcc2 drm/msm/dsi: Enable BURST_MODE for command mode for DSI 6G v1.3+
During a frame transfer in command mode, there could be frequent
LP11 <-> HS transitions when multiple DCS commands are sent mid-frame or
if the DSI controller is running on slow clock and is throttled. To
minimize frame latency due to these transitions, it is recommended to
send the frame in a single burst.

This feature is supported for DSI 6G 1.3 and above, thus enable burst
mode if supported.

274909a85e drm/msm/dpu: Remove redundant prefix/suffix in name of sub-blocks
For a device core dump, the registers of sub-blocks are printed under a
title formatted as <mainBlkName_sblkName>. For example, the csc sub-block
for an SSPP main block "sspp_0" would be printed "sspp_0_sspp_csc0". The
title is clearly redundant due to the duplicate "sspp" and "0" that exist
in both the mainBlkName and sblkName. To eliminate this redundancy, remove
the secondary "sspp" and "0" that exist in the sub-block name by
elimanting the "sspp_" prefix and the concatenation of "num" that results
in the redundant "0" suffix. Remove num parameter altogether from relevant
macros as a consequence of it no longer being used.

The DT of_device.h and of_platform.h date back to the separate

As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

In an error path where the submit is free'd without the job being run,
the hw_fence pointer is simply a kzalloc'd block of memory.  In this
case we should just kfree() it, rather than trying to decrement it's
reference count.  Fortunately we can tell that this is the case by
checking for a zero refcount, since if the job was run, the submit would
be holding a reference to the hw_fence.

Currently struct drm_dsc_config for DSI is populated at display
setup during system boot up. This mechanism works fine with
embedded display but not for pluggable displays as the
struct drm_dsc_config will become stale once external display
is unplugged.

In preparation of adding support for DP DSC support
move storing of DSI DSC struct to atomic_enable() so that same
mechanism will work for both embedded display and pluggable
displays.

27655b9bb9 drm/client: Send hotplug event after registering a client
Generate a hotplug event after registering a client to allow the
client to configure its display. Remove the hotplug calls from the
existing clients for fbdev emulation. This change fixes a concurrency
bug between registering a client and receiving events from the DRM
core. The bug is present in the fbdev emulation of all drivers.

The fbdev emulation currently generates a hotplug event before
registering the client to the device. For each new output, the DRM
core sends an additional hotplug event to each registered client.

If the DRM core detects first output between sending the artificial
hotplug and registering the device, the output's hotplug event gets
lost. If this is the first output, the fbdev console display remains
dark. This has been observed with amdgpu and fbdev-generic.

Fix this by adding hotplug generation directly to the client's
register helper drm_client_register(). Registering the client and
receiving events are serialized by struct drm_device.clientlist_mutex.
So an output is either configured by the initial hotplug event, or
the client has already been registered.

The bug was originally added in commit 6e3f17ee73 ("drm/fb-helper:
generic: Call drm_client_add() after setup is done"), in which adding
a client and receiving a hotplug event switched order. It was hidden,
as most hardware and drivers have at least on static output configured.
Other drivers didn't use the internal DRM client or still had struct
drm_mode_config_funcs.output_poll_changed set. That callback handled

e7fc9398e6 drm/msm/a6xx: Add A610 support
A610 is one of (if not the) lowest-tier SKUs in the A6XX family. It
features no GMU, as it's implemented solely on SoCs with SMD_RPM.
What's more interesting is that it does not feature a VDDGX line
either, being powered solely by VDDCX and has an unfortunate hardware
quirk that makes its reset line broken - after a couple of assert/
deassert cycles, it will hang for good and will not wake up again.

This GPU requires mesa changes for proper rendering, and lots of them
at that. The command streams are quite far away from any other A6XX
GPU and hence it needs special care. This patch was validated both
by running an (incomplete) downstream mesa with some hacks (frames
rendered correctly, though some instructions made the GPU hangcheck
which is expected - garbage in, garbage out) and by replaying RD
traces captured with the downstream KGSL driver - no crashes there,
ever.

Add support for this GPU on the kernel side, which comes down to
pretty simply adding A612 HWCG tables, altering a few values and
adding a special case for handling the reset line.

5a903a44a9 drm/msm/a6xx: Introduce GMU wrapper support
Some (particularly SMD_RPM, a.k.a non-RPMh) SoCs implement A6XX GPUs
but don't implement the associated GMUs. This is due to the fact that
the GMU directly pokes at RPMh. Sadly, this means we have to take care
of enabling & scaling power rails, clocks and bandwidth ourselves.

Reuse existing Adreno-common code and modify the deeply-GMU-infused
A6XX code to facilitate these GPUs. This involves if-ing out lots
of GMU callbacks and introducing a new type of GMU - GMU wrapper (it's
the actual name that Qualcomm uses in their downstream kernels).

This is essentially a register region which is convenient to model
as a device. We'll use it for managing the GDSCs. The register
layout matches the actual GMU_CX/GX regions on the "real GMU" devices
and lets us reuse quite a bit of gmu_read/write/rmw calls.

fa0048a4b1 drm/msm/dp: Free resources after unregistering them
The DP component's unbind operation walks through the submodules to
unregister and clean things up. But if the unbind happens because the DP
controller itself is being removed, all the memory for those submodules
has just been freed.

Change the order of these operations to avoid the many use-after-free
that otherwise happens in this code path.

a7bfb2ad21 drm/msm/dp: Drop aux devices together with DP controller
Using devres to depopulate the aux bus made sure that upon a probe
deferral the EDP panel device would be destroyed and recreated upon next
attempt.

But the struct device which the devres is tied to is the DPUs
(drm_dev->dev), which may be happen after the DP controller is torn
down.

Indications of this can be seen in the commonly seen EDID-hexdump full
of zeros in the log, or the occasional/rare KASAN fault where the
panel's attempt to read the EDID information causes a use after free on
DP resources.

It's tempting to move the devres to the DP controller's struct device,
but the resources used by the device(s) on the aux bus are explicitly
torn down in the error path. The KASAN-reported use-after-free also
remains, as the DP aux "module" explicitly frees its devres-allocated
memory in this code path.

As such, explicitly depopulate the aux bus in the error path, and in the
component unbind path, to avoid these issues.

155fa3a91d drm/msm/dsi: Remove incorrect references to slice_count
Currently, slice_count is being used to calculate word count and
pkt_per_line. Instead, these values should be calculated using slice per
packet, which is not the same as slice_count.

Slice count represents the number of slices per interface, and its value
will not always match that of slice per packet. For example, it is possible
to have cases where there are multiple slices per interface but the panel
specifies only one slice per packet.

Thus, use the default value of one slice per packet and remove slice_count
from the aforementioned calculations.

If the Adreno SMMU is dma-coherent, allocation will fail unless we
disable IO_PGTABLE_QUIRK_ARM_OUTER_WBWA. Skip setting this quirk for the
coherent SMMUs (like we have on sm8350 platform).

Sparse reports plenty of warnings against the a6xx code because of
a6xx_gmu::mmio and a6xx_gmu::rscc members. For some reason they were
defined as __iomem pointers rather than pointers to __iomem memory.
Correct the __iomem attribute.

a8e981ac2d drm/msm/dp: enable HDP plugin/unplugged interrupts at hpd_enable/disable
The internal_hpd flag is set to true by dp_bridge_hpd_enable() and set to
false by dp_bridge_hpd_disable() to handle GPIO pinmuxed into DP controller
case. HDP related interrupts can not be enabled until internal_hpd is set
to true. At current implementation dp_display_config_hpd() will initialize
DP host controller first followed by enabling HDP related interrupts if
internal_hpd was true at that time. Enable HDP related interrupts depends on
internal_hpd status may leave system with DP driver host is in running state
but without HDP related interrupts being enabled. This will prevent external
display from being detected. Eliminated this dependency by moving HDP related
interrupts enable/disable be done at dp_bridge_hpd_enable/disable() directly
regardless of internal_hpd status.

Changes in V3:
-- dp_catalog_ctrl_hpd_enable() and dp_catalog_ctrl_hpd_disable()
-- rewording ocmmit text

Changes in V4:
-- replace dp_display_config_hpd() with dp_display_host_start()
-- move enable_irq() at dp_display_host_start();

Changes in V5:
-- replace dp_display_host_start() with dp_display_host_init()

Changes in V6:
-- squash remove enable_irq() and disable_irq()

e7a2cf8e05 drm/msm/dpu: tidy up some error checking
The "vsync_hz" variable is unsigned int so it can't be less
than zero.  The dpu_kms_get_clk_rate() function used to return a u64
but I previously changed it to return an unsigned long and zero on
error so it matches clk_get_rate().

Change the "vsync_hz" type to unsigned long as well and change the
error checking to check for zero instead of negatives.  This change
does not affect runtime at all.  It's just a clean up.

1531d0b923 drm/msm/dsi: Add phy configuration for MSM8226
MSM8226 uses a modified PLL lock sequence compared to MSM8974, which is
based on the function dsi_pll_enable_seq_m in the msm-3.10 kernel.

Worth noting that the msm-3.10 downstream kernel also will try other
sequences in case this one doesn't work, but during testing it has shown
that the _m sequence succeeds first time also:

  .pll_enable_seqs[0] = dsi_pll_enable_seq_m,
  .pll_enable_seqs[1] = dsi_pll_enable_seq_m,
  .pll_enable_seqs[2] = dsi_pll_enable_seq_d,
  .pll_enable_seqs[3] = dsi_pll_enable_seq_d,
  .pll_enable_seqs[4] = dsi_pll_enable_seq_f1,
  .pll_enable_seqs[5] = dsi_pll_enable_seq_c,
  .pll_enable_seqs[6] = dsi_pll_enable_seq_e,

We may need to expand this in the future.

Changes in v6:
-- split patches, this patch has function handles DPU_PINGPONG_DSC bit

Changes in v9:
-- the original code of assigning dsc related functions to the ops of

2defa907ed drm/msm/dpu: fix the condition for (not) applying QoS to CURSOR SSPP
The function dpu_plane_sspp_update_pipe() contains code to skip enabling
the QoS and OT limitis for CURSOR pipes. However all DPU since sdm845
repurpose DMA SSPP for the cursor planes because they lack the real
CURSOR SSPP. Fix the condition to actually check that the plane is
CURSOR or not.

4a2262c121 drm/msm: Use regular fbdev I/O helpers
Use the regular fbdev helpers for framebuffer I/O instead of DRM's
helpers. Msm does not use damage handling, so DRM's fbdev helpers
are mere wrappers around the fbdev code.

By using fbdev helpers directly within each DRM fbdev emulation,
we can eventually remove DRM's wrapper functions entirely.

Msm's fbdev emulation has been incomplete as it didn't implement
damage handling. Partilly fix this by implementing damage handling
for write and draw operation. It is still missing for mmaped pages.

v4:
	* use initializer macros for struct fb_ops
	* partially support damage handling
v2:
	* use FB_SYS_HELPERS option

50883f733c drm/msm/dpu: replace IS_ERR_OR_NULL with IS_ERR during DSC init
Using IS_ERR_OR_NULL() together with PTR_ERR() is a typical mistake. If
the value is NULL, then the function will return 0 instead of a proper
return code. Moreover dpu_hw_dsc_init() can not return NULL.
Replace the IS_ERR_OR_NULL() call with IS_ERR().

This follows the commit 740828c73a ("drm/msm/dpu: fix error handling
in dpu_rm_init"), which removed IS_ERR_OR_NULL() from RM init code, but
then the commit f2803ee91a ("drm/msm/disp/dpu1: Add DSC support in

bb9f1880ca drm/msm/dpu: Merge setup_- and enable_tearcheck pingpong callbacks
These functions are always called consecutively and are best bundled
together for simplicity, especially when the same structure of callbacks
will be replicated later on the interface block for INTF TE support.
The enable_tearcheck(false) case is now replaced with a more obvious
disable_tearcheck(), encapsulating the original register write with 0.

All SoCs since DPU 5.0.0 have the tear interrupt registers moved out of
the PINGPONG block and into the INTF block.  The new interrupts are
described in dpu_hw_interrupts.c, now wire them up in individual SoC
catalog files by setting the intr_tear_rd_ptr to the IRQ index spcified
in the offset table and enabling this set of DPU interrupts via the

a38a9949a9 drm/msm/dpu: Factor out shared interrupt register in INTF_BLK macro
As the INTF block is going to attain more interrupts that don't share
the same MDP_SSPP_TOP0_INTR register, factor out the _reg argument for
the caller to construct the right interrupt index (register and bit
index) to not make the interrupt bit arguments depend on one of multiple
interrupt register indices.  This brings us more in line with how PP_BLK
specifies its interrupts and allows for better wrapping in the arrays.

Since hardware revision 5.0.0 the TE configuration moved out of the

The existing PP_BLK_TE macro has been removed in favour of directly
passing this feature flag, which has thus far been the only difference
with PP_BLK.  PP_BLK_DITHER has been left in place as its embedded
feature flag already excludes this DPU_PINGPONG_TE bit and differs by
setting the block length to zero, as it only contains a DITHER subblock.

4a7c38ec7d drm/msm/dpu: Move autorefresh disable from CMD encoder to pingpong
This autorefresh disable logic in the physical command-mode encoder
consumes three callbacks to the pingpong block, and will explode in
unnecessary complexity when the same callbacks need to be called on the
interface block instead to accommodate INTF TE support.  To clean this
up, move the logic into the pingpong block under a disable_autorefresh
callback, replacing the aforementioned three get_autorefresh,
setup_autorefresh and get_vsync_info callbacks.

The same logic will have to be replicated to the interface block when it
receives INTF TE support, but it is less complex than constantly
switching on a "has_intf_te" boolean to choose a callback.

values based on the vertical resolution, instead of using the actual
mode polarities.

1e0a97f84d drm/msm/dsi: don't allow enabling 14nm VCO with unprogrammed rate
If the dispcc uses CLK_OPS_PARENT_ENABLE (e.g. on QCM2290), CCF can try
enabling VCO before the rate has been programmed. This can cause clock
lockups and/or other boot issues. Program the VCO to the minimal PLL
rate if the read rate is 0 Hz.

d8dd416cb4 drm/msm/dsi: More properly handle errors in regards to dsi_mgr_bridge_power_on()
In commit 7d8e9a9050 ("drm/msm/dsi: move DSI host powerup to modeset
time") the error handling with regards to dsi_mgr_bridge_power_on()
got a bit worse. Specifically if we failed to power the bridge on then
nothing would really notice. The modeset function couldn't return an
error and thus we'd blindly go forward and try to do the pre-enable.

In commit ec7981e6c6 ("drm/msm/dsi: don't powerup at modeset time
for parade-ps8640") we added a special case to move the powerup back
to pre-enable time for ps8640. When we did that, we didn't try to
recover the old/better error handling just for ps8640.

In the patch ("drm/msm/dsi: Stop unconditionally powering up DSI hosts
at modeset") we've now moved the powering up back to exclusively being
during pre-enable. That means we can add the better error handling
back in, so let's do it. To do so we'll add a new function
dsi_mgr_bridge_power_off() that's matches how errors were handled
prior to commit 7d8e9a9050 ("drm/msm/dsi: move DSI host powerup to
modeset time").

NOTE: Now that we have dsi_mgr_bridge_power_off(), it feels as if we
should be calling it in dsi_mgr_bridge_post_disable(). That would make
some sense, but doing so would change the current behavior and thus
should be a separate patch. Specifically:
* dsi_mgr_bridge_post_disable() always calls dsi_mgr_phy_disable()
  even in the slave-DSI case of bonded DSI. We'd need to add special
  handling for this if it's truly needed.
* dsi_mgr_bridge_post_disable() calls msm_dsi_phy_pll_save_state()
  midway through the poweroff.
* dsi_mgr_bridge_post_disable() has a different order of some of the
  poweroffs / IRQ disables.
For now we'll leave dsi_mgr_bridge_post_disable() alone.

9e15123eca drm/msm/dsi: Stop unconditionally powering up DSI hosts at modeset
In commit 7d8e9a9050 ("drm/msm/dsi: move DSI host powerup to modeset
time"), we moved powering up DSI hosts to modeset time. This wasn't
because it was an elegant design, but there were no better options.

That commit actually ended up breaking ps8640, and thus was born
commit ec7981e6c6 ("drm/msm/dsi: don't powerup at modeset time for
parade-ps8640") as a temporary hack to un-break ps8640 by moving it to
the old way of doing things. It turns out that ps8640 _really_ doesn't
like its pre_enable() function to be called after
dsi_mgr_bridge_power_on(). Specifically (from experimentation, not
because I have any inside knowledge), it looks like the assertion of
"RST#" in the ps8640 runtime resume handler seems like it's not
allowed to happen after dsi_mgr_bridge_power_on()

Recently, Dave Stevenson's series landed allowing bridges some control
over pre_enable ordering. The meaty commit for our purposes is
commit 4fb912e5e1 ("drm/bridge: Introduce pre_enable_prev_first to
alter bridge init order"). As documented by that series, if a bridge
doesn't set "pre_enable_prev_first" then we should use the old ordering.

Now that we have the commit ("drm/bridge: tc358762: Set
pre_enable_prev_first") we can go back to the old ordering, which also
allows us to remove the ps8640 special case.

One last note is that even without reverting commit 7d8e9a9050
("drm/msm/dsi: move DSI host powerup to modeset time"), if you _just_
revert the ps8640 special case and try it out then it doesn't seem to
fail anymore. I spent time bisecting / debugging this and it turns out
to be mostly luck, so we still want this patch to make sure it's
solid. Specifically the reason it sorta works these days is because
we implemented wait_hpd_asserted() in ps8640 now, plus the magic of
"pm_runtime" autosuspend. The fact that we have wait_hpd_asserted()
implemented means that we actually power the bridge chip up just a wee
bit earlier and then the bridge happens to stay on because of
autosuspend and thus ends up powered before dsi_mgr_bridge_power_on().

23bdc972da drm/msm/dpu: use CTL_SC7280_MASK for sm8450's ctl_0
On sm8450 platform the CTL_0 doesn't differ from the rest of CTL blocks,
so switch it to CTL_SC7280_MASK too.

Some background: original commit 100d7ef699 ("drm/msm/dpu: add support
for SM8450") had all (relevant at that time) bit spelled individually.
Then commit 0e91bcbb00 ("drm/msm/dpu: Add SM8350 to hw catalog"),
despite being a mismerge, correctly changed all other CTL entries to use
CTL_SC7280_MASK, except CTL_0.

While the current BLOCK_SOC_MASK style is not ideal (and while we are
working on a better scheme), let's follow its usage as a least minimal
surprise. For example, sc8280xp, a close associate of sm8450, also uses
CTL_SC7280_MASK.

686eb89b10 drm/msm/dpu: tweak lm pairings in msm8998 hw catalog
Change lm blocks pairs so that lm blocks with the same features are
paired together:

LM_0 and LM_1 with PP and DSPP
LM_2 and LM_5 with PP
LM_3 and LM_4

This matches the sdm845 configuration and allows using pp or dspp when 2
lm blocks are needed in the topology. In the previous config the
reservation code could never find an lm pair without a matching feature
set.

85c636284c drm/msm/dp: unregister audio driver during unbind
while binding the code always registers a audio driver, however there
is no corresponding unregistration done in unbind. This leads to multiple
redundant audio platform devices if dp_display_bind and dp_display_unbind
happens multiple times during startup. On X13s platform this resulted in
6 to 9 audio codec device instead of just 3 codec devices for 3 dp ports.

Fix this by unregistering codecs on unbind.

62aeaeaa1b drm/aperture: Remove primary argument
Only really pci devices have a business setting this - it's for
figuring out whether the legacy vga stuff should be nuked too. And
with the preceding two patches those are all using the pci version of
this.

Which means for all other callers primary == false and we can remove
it now.

v2:
- Reorder to avoid compile fail (Thomas)
- Include gma500, which retained it's called to the non-pci version.

v4:
- fix Daniel's S-o-b address

v5:
- add back an S-o-b tag with Daniel's Intel address

tries to access the inexistent host by adding a dt node for it.

Remove the SC7180 struct and point the hw revision match to the
SDM845's one. On a note, this could have been done back when
7180 support was introduced.
