We stopped using the driver initialized date in commit 7fb8af6798
("drm: deprecate driver date") and (eventually) started returning "0"
for drm_version ioctl instead.
Finish the job, and remove the unused date member from struct
drm_driver, its initialization from drivers, along with the common
DRIVER_DATE macros.
v2: Also update drivers/accel (kernel test robot)

The continual trickle of small conversion patches is grating on me, and
is really not helping. Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:
/*
* .remove_new() is a relic from a prototype conversion of .remove().
* New drivers are supposed to implement .remove(). Once all drivers are
* converted to not use .remove_new any more, it will be dropped.
*/
This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.
I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.
Then I just removed the old (sic) .remove_new member function, and this
is the end result. No more unnecessary conversion noise.

DRM's aperture functions have long been implemented as helpers
under drivers/video/ for use with fbdev. Avoid the DRM wrappers by
calling the video functions directly.

Call drm_client_setup() to run the kernel's default client setup
for DRM. Set fbdev_probe in struct drm_driver, so that the client
setup can start the common fbdev client.
The meson driver specifies a preferred color mode of 32. As this
is the default if no format has been given, leave it out entirely.

drm_bridge_connector is a "leaf" driver, belonging to the display
helper, rather than the "CRTC" drm_kms_helper module. Move the driver
to the drm/display and add necessary Kconfig selection clauses.

Pull drm updates from Dave Airlie:
"This is the main pull request for the drm subsystems for 6.10.
In drivers the main thing is a new driver for ARM Mali firmware based
GPUs, otherwise there are a lot of changes to amdgpu/xe/i915/msm and
scattered changes to everything else.

When no mode is set, the utility pin appears to be grounded. No signal
is getting through.
This is problematic because ARC and eARC use this line and may do so even
if no display mode is set.
This change enable the bandgap setting on g12 chip, which fix the problem
with the utility pin. This is done by restoring init values on PHY init and
disable.

The phy is not in a useful state right after init. It will become useful,
including for auxiliary function such as CEC or ARC, after the first mode
is set. This is a problem on systems where the display is using another
interface like DSI or CVBS.
This change refactor the init and mode change callback to power up the PHY
on init and leave only what is necessary for mode changes in the related
function. This is enough to fix CEC operation when HDMI display is not
enabled.

This reverts commit c0e0f13935, as helper
code should always be selected by the driver that needs it, for the
convenience of the final user configuring a kernel.
The user who configures a kernel should not need to know which helpers
are needed for the driver he is interested in. Making a driver depend
on helper code means that the user needs to know which helpers to enable
first, which is very user-unfriendly.

Rename meson_encoder_{cvbs,dsi,hdmi}_init() to
meson_encoder_{cvbs,dsi,hdmi}_probe() so it's clear that these functions
are used at probe time during driver initialization. Also switch all
error prints inside those functions to use dev_err_probe() for
consistency.
This makes the code more straight forward to read and makes the error
prints within those functions consistent (by logging all -EPROBE_DEFER
with dev_dbg(), while actual errors are logged with dev_err() and get
the error value printed).

Stop calling drm_bridge_remove() for bridges allocated/managed by other
drivers in the remove paths of meson_encoder_{cvbs,dsi,hdmi}.
drm_bridge_remove() unregisters the bridge so it cannot be used
anymore. Doing so for bridges we don't own can lead to the video
pipeline not being able to come up after -EPROBE_DEFER of the VPU
because we're unregistering a bridge that's managed by another driver.
The other driver doesn't know that we have unregistered it's bridge
and on subsequent .probe() we're not able to find those bridges anymore
(since nobody re-creates them).
This fixes probe errors on Meson8b boards with the CVBS outputs enabled.

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 ignored (apart
from emitting a warning) 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. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
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.

Right now clocking value selection code is prioritising RGB, YUV444 modes
over YUV420 for HDMI2 sinks. However, because of the bus format selection
procedure in dw-hdmi, for HDMI2 sinks YUV420 is the format that will always
be picked during the drm bridge chain check stage.
Later on dw_hdmi_setup will configure a colour space based on the bus
format that doesn't match the pixel value we had calculated as described
above.
Fix it by bringing back dw-hdmi bus format check when picking the right
pixel clock.

Only DW-HDMI currently needs components since it reuses
the drm-meson driver context to access HHI registers (sic).
Once this is solved, we can get rid on components.
Until now, limit the components matching to the dw-hdmi compatibles
we know to require this hack, for other bridges simply use probe defer
instead and get over this components sitation.
The back story is that we simply cannot attach DSI adapters bridges
if we use components, only DSI panels, this is because we bind/unbind
the DSI controller at each drm-meson driver master bind tentative.
With this the I2C DSI bridge is unable to find the DSI controller
host and everything fails to probe.
This will simplify a lot adding new or older HDMI bridges.

If the case the HDMI controller fails to bind, we try to unbind
all components before calling drm_dev_put() which makes drm_bridge_detach()
crash because unbinding the HDMI controller frees the bridge memory.
The solution is the unbind all components at the end like in the remove

Merge v6.3-rc4 into drm-next
I just landed the fence deadline PR from Rob that a bunch of drivers
want/need to apply driver-specific patches. Backmerge -rc4 so that
they don't have to be stuck on -rc2 for no reason at all.

devm_regulator_get_enable_optional() returns -ENODEV if requested
optional regulator is not present. Adjust code for that, because in the
67d0a30128 I've incorrectly assumed that it also returns 0 when
regulator is not present.

Use the fbdev emulation that is optimized for DMA helpers. Avoids
possible shadow buffering and makes the code simpler.

Playing media with a resolution smaller than the crtc size requires the
video overlay to be scaled for output and GXM boards display a 1px pink
line on the bottom of the scaled overlay. Comparing with the downstream
vendor driver revealed VPP_DUMMY_DATA not being set [0].
Setting VPP_DUMMY_DATA prevents the 1px pink line from being seen.

Merge v6.2-rc6 into drm-next
Due to holidays we started -next with more -fixes in-flight than
usual, and people have been asking where they are. Backmerge to get
things better in sync.
Conflicts:
- Tiny conflict in drm_fbdev_generic.c between variable rename and
missing error handling that got added.
- Conflict in drm_fb_helper.c between the added call to vgaswitcheroo
in drm_fb_helper_single_fb_probe and a refactor patch that extracted
lots of helpers and incidentally removed the dev local variable.
Readd it to make things compile.

Having a bigger number of FIFO lines held after vsync is only useful to
SoCs using AFBC to give time to the AFBC decoder to be reset, configured
and enabled again.
For SoCs not using AFBC this, on the contrary, is causing on some
displays issues and a few pixels vertical offset in the displayed image.
Conditionally increase the number of lines held after vsync only for
SoCs using AFBC, leaving the default value for all the others.
Fixes: 24e0d4058e ("drm/meson: hold 32 lines after vsync to give time for AFBC start")
