drm: Use state helper instead of CRTC state pointer
Many drivers reference the crtc->pointer in order to get the current CRTC
state in their atomic_begin or atomic_flush hooks, which would be the new
CRTC state in the global atomic state since _swap_state happened when those
hooks are run.

Use the drm_atomic_get_new_crtc_state helper to get that state to make it
more obvious.

This was made using the coccinelle script below:

a39855076c drm/cma-helper: Make default object functions the default
As GEM object functions are now mandatory, DRM drivers based on CMA
helpers either set them in their implementation of gem_create_object,
or use the default via drm_gem_cma_create_object_default_funcs().

Simplify this by setting the default CMA object functions for all
objects that don't have any functions of their own. Follows the pattern
of similar code in SHMEM and VRAM helpers. The function
drm_gem_cma_create_object_default_funcs() is redundant and therefore
being removed.

222ec45f4c drm/fb_helper: Support framebuffers in I/O memory
At least sparc64 requires I/O-specific access to framebuffers. This
patch updates the fbdev console accordingly.

For drivers with direct access to the framebuffer memory, the callback
functions in struct fb_ops test for the type of memory and call the rsp
fb_sys_ of fb_cfb_ functions. Read and write operations are implemented
internally by DRM's fbdev helper.

For drivers that employ a shadow buffer, fbdev's blit function retrieves
the framebuffer address as struct dma_buf_map, and uses dma_buf_map
interfaces to access the buffer.

The bochs driver on sparc64 uses a workaround to flag the framebuffer as
I/O memory and avoid a HW exception. With the introduction of struct
dma_buf_map, this is not required any longer. The patch removes the rsp
code from both, bochs and fbdev.

v7:
	* use min_t(size_t,) (kernel test robot)
	* return the number of bytes read/written, if any (fbdev testcase)
v5:
	* implement fb_read/fb_write internally (Daniel, Sam)
v4:
	* move dma_buf_map changes into separate patch (Daniel)
	* TODO list: comment on fbdev updates (Daniel)

49a3f51dfe drm/gem: Use struct dma_buf_map in GEM vmap ops and convert GEM backends
This patch replaces the vmap/vunmap's use of raw pointers in GEM object
functions with instances of struct dma_buf_map. GEM backends are
converted as well. For most of them, this simply changes the returned type.

TTM-based drivers now return information about the location of the memory,
either system or I/O memory. GEM VRAM helpers and qxl now use ttm_bo_vmap()

Each function is a simplified version of TTM's existing kmap code. Both

cc5f7e2fcb drm/bridge: sii902x: Enable I/O and core VCC supplies if present
On the SII9022, the IOVCC and CVCC12 supplies must reach the correct
voltage before the reset sequence is initiated. On most boards, this
assumption is true at boot-up, so initialization succeeds.

However, when we try to initialize the chip with incorrect supply
voltages, it will not respond to I2C requests. sii902x_probe() fails
with -ENXIO.

To resolve this, look for the "iovcc" and "cvcc12" regulators, and
make sure they are enabled before starting the reset sequence. If
these supplies are not available in devicetree, then they will default
to dummy-regulator. In that case everything will work like before.

This was observed on a STM32MP157C-DK2 booting in u-boot falcon mode.
On this board, the supplies would be set by the second stage
bootloader, which does not run in falcon mode.

982f589bde drm/bridge: ti-sn65dsi86: Update reply on aux failures
We should be setting the drm_dp_aux_msg::reply field if a NACK or a
SHORT reply happens. Update the error bit handling logic in
ti_sn_aux_transfer() to handle these cases and notify upper layers that
such errors have happened. This helps the retry logic understand that a
timeout has happened, or to shorten the read length if the panel isn't
able to handle the longest read possible.

Note: I don't have any hardware that exhibits these code paths so this
is written based on reading the datasheet for this bridge and inspecting
the code and how this is called.

Changes in v2:
 - Move WRITE_STATUS_UPDATE check from case to assignment

Changes in v2:
 - Handle WRITE_STATUS_UPDATE properly

b38558e305 drm/bridge: ti-sn65dsi86: Make polling a busy loop
There's no reason we need to wait here to poll a register over i2c. The
i2c bus is inherently slow and delays are practically part of the
protocol because we have to wait for the device to respond to any
request for a register. Let's rely on the sleeping of the i2c controller
instead of adding any sort of delay here in the bridge driver.

These register reads and writes are sometimes directly next to each

APIs to get the data with one transfer instead of multiple i2c
transfers. This helps cut down on the number of transfers in the case of
something like reading an EDID where we read in blocks of 16 bytes at a
time and the last for loop here is sending an i2c transfer for each of
those 16 bytes, one at a time. Ouch!

Pull drm fixes from Dave Airlie:
 "It's Friday here so that means another installment of drm fixes to
  distract you from the counting process.

  Changes all over the place, the amdgpu changes contain support for a
  new GPU that is close to current one already in the tree (Green
  Sardine) so it shouldn't have much side effects.

  Otherwise imx has a few cleanup patches and fixes, amdgpu and i915
  have around the usual smattering of fixes, fonts got constified, and
  vc4/panfrost has some minor fixes. All in all a fairly regular rc3.

  We have an outstanding nouveau regression, but the author is looking

drm/vc4: replace idr_init() by idr_init_base()
idr_init() uses base 0 which is an invalid identifier for this driver.
The idr_alloc for this driver uses VC4_PERFMONID_MIN as start value for
ID range and it is #defined to 1. The new function idr_init_base allows
IDR to set the ID lookup from base 1. This avoids all lookups that
otherwise starts from 0 since 0 is always unused / available.

70a59dd829 drm/<drivers>: Constify struct drm_driver
Only the following drivers aren't converted:
- amdgpu, because of the driver_feature mangling due to virt support.
  Subsequent patch will address this.
- nouveau, because DRIVER_ATOMIC uapi is still not the default on the
  platforms where it's supported (i.e. again driver_feature mangling)
- vc4, again because of driver_feature mangling
- qxl, because the ioctl table is somewhere else and moving that is
  maybe a bit too much, hence the num_ioctls assignment prevents a
  const driver structure.
- arcpgu, because that is stuck behind a pending tiny-fication series
  from me.
- legacy drivers, because legacy requires non-const drm_driver.

Note that for armada I also went ahead and made the ioctl array const.

Only cc'ing the driver people who've not been converted (everyone else
is way too much).

v2: Fix one misplaced const static, should be static const (0day)

v3:
- Improve commit message (Sam)

8f5c7aa078 drm: Allow const struct drm_driver
It's nice if a big function/ioctl table like this is const. Only
downside here is that we need a few more #ifdef to paper over the
differences when CONFIG_DRM_LEGACY is enabled. Maybe provides more
motivation to sunset that horror show :-)

v2:
- Fix super important checkpatch warning (Sam)
- Update the kerneldoc example too (Sam)

57bb1ee603 drm: Compile out legacy chunks from struct drm_device
This means some very few #ifdef in code, but it allows us to
enlist the compiler to make sure this stuff isn't used anymore.

More important, only legacy drivers change drm_device (for the
legacy_dev_list shadow attach management), therefore this is
prep to allow modern drivers to have a const driver struct. Which
is nice, because there's a ton of function pointers in there.

384bc5e059 drm/radeon: Stop changing the drm_driver struct
With only the kms driver left, we can fold this in. This means
we need to move the ioctl table, which means one additional ioctl
must be defined in headers.

Also there's a conflict between the radeon_init macro and the module
init function, so rename the module functions to avoid that.

5d4c1edf0d drm/qxl: replace idr_init() by idr_init_base()
idr_init() uses base 0 which is an invalid identifier for this driver.
The idr_alloc for this driver uses 1 as start value for ID range. The
new function idr_init_base allows IDR to set the ID lookup from base 1.
This avoids all lookups that otherwise starts from 0 since 0 is always
unused / available.

returns an error), it gets polled via detect().

514ad1b6bb drm/amdgpu: Fix Arcturus fan speed reporting
Arcturus doesn't have a fan. The assumption of "if the manual fan
control bit isn't set, it's on automatic mode" does not hold true if the
fan is missing, and results in exposing an invalid value for fan speed.

The SMU metrics table accurately reflects the lack of fan and will
return 0 for the fan speed. Trying to use the
smu_v11_0_get_fan_speed_rpm function will return invalid data, so just
stick with the SMU metrics for Arcturus
