Updating drm-misc-next to the state of Linux v6.6-rc2.

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by for struct vc4_perfmon.

Based on grepping through the source code these drivers appear to be
missing a call to drm_atomic_helper_shutdown() at system shutdown
time. Among other things, this means that if a panel is in use that it
won't be cleanly powered off at system shutdown time.
The fact that we should call drm_atomic_helper_shutdown() in the case
of OS shutdown/restart comes straight out of the kernel doc "driver
instance overview" in drm_drv.c.

Pull sound updates from Takashi Iwai:
"We've received a fairly wide range of changes at this time, including
for ALSA and ASoC core, but all of them are rather small changes.
Here are some highlights:
ALSA / ASoC Core:
- Fixes of inconsistent locking around control API helpers
- A few new control API functions and cleanups
- Workarounds for potential UAFs by delayed kobj releases
- Unified PCM copy ops with iov_iter
- Continued efforts for ASoC API cleanups
ASoC:
- An adaptor to allow use of IIO DACs and ADCs in ASoC which pulls in
some IIO changes
- Create a library function for intlog10() and use it in the NAU8825
driver
- Convert drivers to use the more modern maple tree register cache
- Lots of work on the SOF framework, AMD and Intel drivers, including
a lot of cleanup and new device support
- Standardization of the presentation of jacks from drivers
- Provision of some generic sound card DT properties
- Support for AMD Van Gogh, AMD machines with MAX98388 and NAU8821,
AWInic AW88261, Cirrus Logic CS35L36 and CS42L43, various Intel
platforms including AVS machines with ES8336 and RT5663, Mediatek
MT7986, NXP i.MX93, RealTek RT1017 and StarFive JH7110
Others:
- New test coverage including ASoC and topology tests in KUnit; this
also involves enabling UML builds of ALSA since that's the default
KUnit test environment which pulls in the addition of some stubs to
the driver
- More enhancement of pcmtest driver
- A few fixes / enhancements of MIDI 2.0 UMP core
- Using PCI definitions in allover HD-audio code
- Support for Cirrus CS35L56 and TI TAS2781 HD-audio sub-codecs
- CS35L41 HD-audio sub-codec improvements
- Continued emu10k1 improvements"

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.

Drivers might not support all colorspaces defined in
dp_colorspaces and hdmi_colorspaces. This results in
undefined behavior when userspace is setting an
unsupported colorspace.
Allow drivers to pass the list of supported colorspaces
when creating the colorspace property.
v2:
- Use 0 to indicate support for all colorspaces (Jani)
- Print drm_dbg_kms message when drivers pass 0
to signal that drivers should specify supported
colorspaecs explicity (Jani)
v3:
- Move changes to create a common colorspace_names array
to separate patch
v6:
- Avoid magic when passing 0 for supported_colorspaces;
be explicit in treating it as "all DP/HDMI"

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 vc4 drm drivers from always returning zero in the
remove callback to the void returning variant.

YUV444 and YUV422 actually require the same matrix, but programmed

We've dealt with it in the past by having two matrices, with the one

On VC4, the TV margins on the HDMI connector are implemented by scaling
the planes.
However, if only the TV margins or the connector are changed by a new
state, the planes ending up on that connector won't be. Thus, they won't
be updated properly and we'll effectively ignore that change until the
next commit affecting these planes.
Let's make sure to add all the planes attached to the connector so that
we can update them properly.

It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.

On the RaspberryPi0-3, the HSM clock was provided by the clk-bcm2835
driver, but on the Pi4 it was provided by the firmware through the
clk-raspberrypi driver.
The clk-bcm2835 driver registers the HSM clock using the
CLK_SET_RATE_GATE flag that prevents any modification to the rate while
the clock is active.
This meant that we needed to call clk_set_min_rate() before our call to
pm_runtime_resume_and_get() since our runtime_resume implementation
needs to enable the HSM clock for the HDMI controller registers to be
functional.
However, the HSM clock is part of the HDMI power domain which might not
be powered prior to the pm_runtime_resume_and_get() call, so we could
end up changing the rate of the HSM clock while its power domain was
disabled.
We recently changed the backing driver for the RaspberryPi0-3 to
clk-raspberrypi though, which doesn't have such restrictions. We can
thus move the clk_set_min_rate() after our call to runtime_resume and
avoid the access while the power domain is disabled.

extreme reduced blanking
The formula that determines the core clock requirement based on pixel
clock and blanking has been determined experimentally to minimise the
clock while supporting all modes we've seen.
A new reduced blanking mode (4kp60 at 533MHz rather than the standard
594MHz) has been seen that doesn't produce a high enough clock and
results in "flip_done timed out" error.
Increase the setup cost in the formula to make this work. The result is
a reduced blanking mode increases by up to 7MHz while leaving the
standard timing
mode untouched

Issue is some displays go blank at the point of firmware to kms
handover. Plugging/unplugging hdmi cable, power cycling display, or
switching standby off/on
typically resolve this case.
Finally managed to find a display that suffers from this, and track down
the issue.
The firmware uses AVMUTE in normal operation. It will set AVMUTE before
disabling hdmi clocks and phy. It will clear AVMUTE after clocks and phy
are set up for a new hdmi mode.
But with the hdmi handover from firmware to kms, AVMUTE will be set by
firmware.
kms driver typically has no GCP packet (except for deep colour modes).
The spec isn't clear on whether to consider the AVMUTE as continuing
indefinitely in the absence of a GCP packet, or to consider that state
to have ended.
Most displays behave as we want, but there are a number (from multiple
manufacturers) which need to see AVMUTE cleared before displaying a
picture.
Lets just always enable GCP packet with AVMUTE cleared. That resolves
the issue on problematic displays.
From HDMI 1.4 spec:
A CD field of zero (Color Depth not indicated) shall be used whenever
the Sink does not indicate support for Deep Color. This value may
also be used in Deep Color mode to transmit a GCP indicating only
non-Deep Color information (e.g. AVMUTE).
So use CD=0 where we were previously not enabling a GCP.

YUV images can either be presented as one allocation with offsets
for the different planes, or multiple allocations with 0 offsets.
The driver only ever calls drm_fb_[dma|cma]_get_gem_obj with plane
index 0, therefore any application using the second approach was
incorrectly rendered.
Correctly determine the address for each plane, removing the
assumption that the base address is the same for each.

Commit 374146cad469 ("drm/vc4: Switch to drmm_mutex_init") converted,
among other functions, vc4_create_object() to use drmm_mutex_init().
However, that function is used to allocate a BO, and therefore the
mutex needs to be freed much sooner than when the DRM device is removed
from the system.
For each buffer allocation we thus end up allocating a small structure
as part of the DRM-managed mechanism that is never freed, eventually
leading us to no longer having any free memory anymore.
Let's switch back to mutex_init/mutex_destroy to deal with it properly.
