ec85147a35 drm/panel: sharp-lq101r1sx01: Fixed reversed "if" in remove
Commit d7d473d846 ("drm/panel: sharp-lq101r1sx01: Don't call disable
at shutdown/remove") had a subtle bug. We should be calling
sharp_panel_del() when the "sharp" variable is non-NULL, not when it's
NULL. Fix.

Merge v6.10-rc6 into drm-next

The exynos-next pull is based on a newer -rc than drm-next. hence
backmerge first to make sure the unrelated conflicts we accumulated
don't end up randomly in the exynos merge pull, but are separated out.

Conflicts are all benign: Adjacent changes in amdgpu and fbdev-dma
code, and cherry-pick conflict in xe.

panel-jadard-jd9365da-h3 driver.Hence,we add a new compatible

Although they have the same control IC, the two panels are different,
and the timing will be slightly different, so we added some variables
in struct jadard_panel_desc to control the timing.

38cae7b626 drm/panel: jd9365da: Modify the method of sending commands
Currently, the init_code of the jd9365da driver is placed
in the enable() function and sent, but this seems to take
a long time. It takes 17ms to send each instruction (an init
code consists of about 200 instructions), so it takes
about 3.5s to send the init_code. So we moved the sending
of the inti_code to the prepare() function, and each
instruction seemed to take only 25μs.

We checked the DSI host and found that the difference in
command sending time is caused by the different modes of
the DSI host in prepare() and enable() functions.
Our DSI Host only supports sending cmd in LP mode, The
prepare() function can directly send init_code (LP->cmd)
in LP mode, but the enable() function is in HS mode and
needs to switch to LP mode before sending init code
(HS->LP->cmd->HS). Therefore, it takes longer to send
the command.

51e1fb144f drm/panel-edp: drop several legacy panels
The panel-edp driver supports legacy compatible strings for several eDP
panels which were never used in DT files present in Linux tree and most
likely have never been used with the upstream kernel. Drop compatibles
for these panels in favour of using a generic "edp-panel" device on the
AUX bus.

Add a fat warning against adding new panel compatibles to the panel-edp
driver. All new users of the eDP panels are supposed to use the generic
"edp-panel" compatible device on the AUX bus. The remaining compatibles
are either used by the existing DT or were used previously and are
retained for backwards compatibility.

78f15847bd drm/panel: raydium-rm67191: Don't call unprepare+disable at shutdown
It's the responsibility of a correctly written DRM modeset driver to
call drm_atomic_helper_shutdown() at shutdown time and that should be
disabling / unpreparing the panel if needed. Panel drivers shouldn't
be calling these functions themselves.

A recent effort was made to fix as many DRM modeset drivers as
possible [1] [2] [3] and most drivers are fixed now.

A grep through mainline for compatible strings used by this driver
indicates that it is used by IMX boards. The IMX driver appears to be
correctly calling drm_atomic_helper_shutdown() so we can remove the
calls.

b7c906d680 drm/panel: raydium-rm67191: Stop tracking enabled
As talked about in commit d2aacaf073 ("drm/panel: Check for already
prepared/enabled in drm_panel"), we want to remove needless code from
panel drivers that was storing and double-checking the
prepared/enabled state. Even if someone was relying on the
double-check before, that double-check is now in the core and not
needed in individual drivers.

The conversion of the rm67191 panel driver follows many of the other
panel drivers but has a few differences that need to be called out.

Like in commit 1e0465eb16 ("drm/panel: otm8009a: Don't double check
prepared/enabled"), this panel also uses the "prepared" flag to
prevent the backlight functions from running when the panel is powered
off. This is probably not the safest thing to do but the old behavior
was preserved. See the discussion in the otm8009a patch. Because of
this, I've left the driver tracking "prepared" but removed its
tracking of "enabled".

NOTE: as part of this, transition the panel's direct calls to its
disable/unprepare functions in shutdown to call through DRM panel.

As talked about in commit d2aacaf073 ("drm/panel: Check for already
prepared/enabled in drm_panel"), we want to remove needless code from
panel drivers that was storing and double-checking the
prepared/enabled state. Even if someone was relying on the
double-check before, that double-check is now in the core and not
needed in individual drivers.

c8f67cd1d9 drm/panel: jdi-lt070me05000: Don't call disable at shutdown/remove
It's the responsibility of a correctly written DRM modeset driver to
call drm_atomic_helper_shutdown() at shutdown time and that should be
disabling / unpreparing the panel if needed. Panel drivers shouldn't
be calling these functions themselves.

A recent effort was made to fix as many DRM modeset drivers as
possible [1] [2] [3] and most drivers are fixed now.

A grep through mainline for compatible strings used by this driver
indicates that it is used by Qualcomm boards. The Qualcomm driver
appears to be correctly calling drm_atomic_helper_shutdown() so we can
remove the calls.

Limited information is available online however the panel timing values
(below) have been obtained from the vendor BSP. The panel appears to
integrate a NV3052C LCD driver (or clone). Available devices address it
in SPI/RGB mode, with the timing signals generated from the device
SoC (Allwinner H700) and passed through.

Add a panel definition and display mode to the existing NV3502C driver.

It was assumed during bringup that the initialisation sequence was the
same as the existing Fascontek FS035VG158 panel, proved working during
experimentation, however subsequent dumping of the init sequence with a
logic analyser confirms one small change to VCOM_ADJ3 from 0x4a to 0x44,
therefore a separate set of registers is also added.

Timings:
           | Active |  FP  | Sync |  BP  | Total
-----------|--------|------|------|------|-------
Horizontal |   640  |  64  |  20  |  46  |  770
  Vertical |   480  |  21  |   4  |  15  |  520
