Change the infix for fbdev's I/O-memory helpers from _IO_ to _IOMEM_
to distiguish them from other types of I/O, such as file operations.
The helpers operate on memory ranges in the I/O address space and the
naming should make this clear. Adapt all users. No functional changes.

As we gain more tests, boilerplate to allocate an atomic state and free
it starts to be there more and more as well.
In order to reduce the allocation boilerplate, we can create a helper
to create that atomic state, and call an action when the test is done.
This will also clean up the exit path.

When CONFIG_IO is disabled, above two variables are not used,
since the place where it is used is inclueded in the macro
CONFIG_OF.
Even for drivers that do not depend on CONFIG_OF, it's almost
always better to leave out the of_match_ptr(), since the only
thing it can possibly do is to save a few bytes of .text if a
driver can be used both with and without it. Hence we remove

Currently we use the drm_dp_dpcd_read_caps() helper in the DRM side of
nouveau in order to read the DPCD of a DP connector, which makes sure we do
the right thing and also check for extended DPCD caps. However, it turns
out we're not currently doing this on the nvkm side since we don't have
access to the drm_dp_aux structure there - which means that the DRM side of
the driver and the NVKM side can end up with different DPCD capabilities
for the same connector.
Ideally in order to fix this, we just want to use the
drm_dp_read_dpcd_caps() helper in nouveau. That's not currently possible
though, and is going to depend on having a bunch of the DP code moved out
of nvkm and into the DRM side of things as part of the GSP enablement work.
Until then however, let's workaround this problem by porting a copy of
drm_dp_read_dpcd_caps() into NVKM - which should fix this issue.

Aspeed always report the display port as "connected", because it
doesn't set a .detect_ctx callback.
Fix this by providing the proper detect callback for astdp and dp501.
This also fixes the following regression:
Since commit fae7d186403e ("drm/probe-helper: Default to 640x480 if no
EDID on DP") The default resolution is now 640x480 when no monitor is
connected. But Aspeed graphics is mostly used in servers, where no monitor
is attached. This also affects the remote BMC resolution to 640x480, which
is inconvenient, and breaks the anaconda installer.

Most aspeed devices have a BMC, which allows to remotely see the screen.
Also in the common use case, those servers don't have a display connected.
So add a Virtual connector, to reflect that even if no display is
connected, the framebuffer can still be seen remotely.
This prepares the work to implement a detect_ctx() for the Display port
connector.

This reverts commit a6a00d7e8ffd78d1cdb7a43f1278f081038c638f.
This commit is redundant, as the root cause that resulted in a false
positive was fixed by commit 27f644dc5a77f8d9 ("x86: kmsan: use C
versions of memset16/memset32/memset64").

All debug messages in drm_gem_framebuffer_helper.c use drm_dbg_kms(),
except for one, which uses drm_dbg().
Replace the outlier by drm_dbg_kms() to restore consistency.

Currently, it is possible for the composer to be set as enabled and then
as disabled without a proper call for the vkms_vblank_simulate(). This
is problematic, because the driver would skip one CRC output, causing CRC
tests to fail. Therefore, we need to make sure that, for each time the
composer is set as enabled, a composer job is added to the queue.
In order to provide this guarantee, add a mutex that will lock before
the composer is set as enabled and will unlock only after the composer
job is added to the queue. This way, we can have a guarantee that the
driver won't skip a CRC entry.
This race-condition is affecting the IGT test "writeback-check-output",
making the test fail and also, leaking writeback framebuffers, as the
writeback job is queued, but it is not signaled. This patch avoids both
problems.
[v2]:
* Create a new mutex and keep the spinlock across the atomic commit in

Support a 1D gamma LUT with interpolation for each color channel on the
VKMS driver. Add a check for the LUT length by creating
vkms_atomic_check().
Enable VKMS to run the test igt@kms_plane@pixel-format.
Tested with:
igt@kms_color@gamma
igt@kms_color@legacy-gamma
igt@kms_color@invalid-gamma-lut-sizes
v2:
- Add interpolation between the values of the LUT (Simon Ser)
v3:
- s/ratio/delta (Pekka)
- s/color_channel/channel_value (Pekka)
- s/lut_area/lut_channel
- Store the `drm_color_lut`, `lut_length`, and
`channel_value2index_ratio` inside a struct called `vkms_lut`
(Pekka)
- Pre-compute some constants values used through the LUT procedure
(Pekka)
- Change the switch statement to a cast to __u16* (Pekka)
- Make the apply_lut_to_channel_value return the computation result
(Pekka)
v4:
- Add a comment explaining that `enum lut_area` depends on the
layout of `struct drm_color_lut` (Pekka)
- Remove unused variable (kernel test robot)
v5:
- Mention that this will make it possible to run the test
igt@kms_plane@pixel-format (Maíra)
- s/had/has (Maíra)

Some Tegra device-trees may specify a video output graph, which involves
MHL bridge/simple bridge and/or connector framework. This patch adds
support for the bridge/connector attached to the HDMI output, allowing
us to model the hardware properly.

Currently, engine drivers only enable runtime PM during the host1x
init callback. This can happen slightly later than the probe, which
can cause the power domain to intermittently not be turned off after
probe.
My hypothesis is that there is a race condition between the post-probe
power domain poweroff that is done from a queued work, and the
pm_runtime_enable call happening in the host1x init callback.
If the pm_runtime_enable call happens first, everything is OK and
the power off work can disable the power domain as PM runtime is
enabled and the device is runtime suspended. If power off work runs
first, PM runtime is still disabled for the device and the domain
must be kept powered.
Resolve the issue by moving the runtime PM enablement to the
probe function.
