Backmerge tag 'v5.18-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux into drm-next

Linux 5.18-rc5

There was a build fix for arm I wanted in drm-next, so backmerge rather then cherry-pick.

Thomas Zimmermann 644edf52b6 drm/display: Move SCDC helpers into display-helper library
SCDC is the Status and Control Data Channel for HDMI. Move the SCDC
helpers into display/ and split the header into files for core and
helpers. Update all affected drivers. No functional changes.

To avoid the proliferation of Kconfig options, SCDC is part of DRM's
support for HDMI. If necessary, a new option could make SCDC an
independent feature.

Thomas Zimmermann 4fc8cb47fc drm/display: Move HDMI helpers into display-helper module
Move DRM's HMDI helpers into the display/ subdirectoy and add it
to DRM's display helpers. Update all affected drivers. No functional
changes.

The HDMI helpers were implemented in the EDID and connector code, but
are actually unrelated. With the move to the display-helper library, we
can remove the dependency on drm_edid.{c,h} in some driver's HDMI source
files.

Several of the HDMI helpers remain in EDID code because both share parts
of their implementation internally. With better refractoring of the EDID
code, those HDMI helpers could be moved into the display-helper library
as well.

v3:
	* fix Kconfig dependencies (Javier)
v2:
	* reduce HDMI helpers to avoid exporting functions (Jani)

drm/vc4: hdmi: Replace drm_detect_hdmi_monitor() with is_hdmi
Once EDID is parsed, the monitor HDMI support information is cached in
drm_display_info.is_hdmi by drm_parse_hdmi_vsdb_video().

This driver calls drm_detect_hdmi_monitor() to receive the same
information and stores its own cached value in
vc4_hdmi_encoder.hdmi_monitor, which is less efficient.

Avoid calling drm_detect_hdmi_monitor() and use drm_display_info.is_hdmi
instead. This also allows to remove vc4_hdmi_encoder.hdmi_monitor.

drm_detect_hdmi_monitor() is called in vc4_hdmi_connector_detect() and
vc4_hdmi_connector_get_modes(). In both cases it is safe to rely on
drm_display_info.is_hdmi as shown by ftrace:

$ sudo trace-cmd record -p function_graph -l "vc4_hdmi_*" -l "drm_*"

drm/vc4: txp: Force alpha to be 0xff if it's disabled
If we use a format that has padding instead of the alpha component (such
as XRGB8888), it appears that the Transposer will fill the padding to 0,
disregarding what was stored in the input buffer padding.

This leads to issues with IGT, since it will set the padding to 0xff,
but will then compare the CRC of the two frames which will thus fail.
Another nice side effect is that it is now possible to just use the
buffer as ARGB.

drm/vc4: txp: Don't set TXP_VSTART_AT_EOF
The TXP_VSTART_AT_EOF will generate a second VSTART signal to the HVS.
However, the HVS waits for VSTART to enable the FIFO and will thus start
filling the FIFO before the start of the frame.

This leads to corruption at the beginning of the first frame, and
content from the previous frame at the beginning of the next frames.

Since one VSTART is enough, let's get rid of it.

drm/vc4: hvs: Reset muxes at probe time
By default, the HVS driver will force the HVS output 3 to be muxed to
the HVS channel 2. However, the Transposer can only be assigned to the
HVS channel 2, so whenever we try to use the writeback connector, we'll
mux its associated output (Output 2) to the channel 2.

This leads to both the output 2 and 3 feeding from the same channel,
which is explicitly discouraged in the documentation.

In order to avoid this, let's reset all the output muxes to their reset
value.

atomic_flush will be called for each CRTC even if they aren't enabled.

The whole code we have there will thus run without a properly affected

Fortunately, the DRM_PLANE_COMMIT_ACTIVE_ONLY flag will skip the CRTC
atomic_begin and atomic_flush, and the planes atomic_update, if they
aren't enabled.

Our plane atomic_update is a nop, and atomic_begin will copy the current
HVS channel to the vc4_crtc structure for the interrupt handler to
consume, but the handler won't run if the CRTC is disabled. So in the
end, it will only skip our CRTC atomic_flush, which is what we want.

Linus Torvalds 266d17a8c0 Driver core changes for 5.18-rc1
Here is the set of driver core changes for 5.18-rc1.
 
 Not much here, primarily it was a bunch of cleanups and small updates:
 	- kobj_type cleanups for default_groups
 	- documentation updates
 	- firmware loader minor changes
 	- component common helper added and take advantage of it in many
 	  drivers (the largest part of this pull request).
 
 There will be a merge conflict in drivers/power/supply/ab8500_chargalg.c
 with your tree, the merge conflict should be easy (take all the
 changes).
 
 All of these have been in linux-next for a while with no reported
 problems.

drm/vc4: hdmi: Support HDMI YUV output
In addition to the RGB444 output, the BCM2711 HDMI controller supports
the YUV444 and YUV422 output formats.

Let's add support for them in the driver, but still use RGB as the
preferred format.

drm/vc4: hdmi: Always try to have the highest bpc
Currently we take the max_bpc property as the bpc value and do not try
anything else.

However, what the other drivers seem to be doing is that they would try
with the highest bpc allowed by the max_bpc property and the hardware
capabilities, test if it results in an acceptable configuration, and if
not decrease the bpc and try again.

Let's use the same logic.

drm/vc4: Use drm_mode_copy()
struct drm_display_mode embeds a list head, so overwriting
the full struct with another one will corrupt the list
(if the destination mode is on a list). Use drm_mode_copy()
instead which explicitly preserves the list head of
the destination mode.

Even if we know the destination mode is not on any list
using drm_mode_copy() seems decent as it sets a good
example. Bad examples of not using it might eventually
get copied into code where preserving the list head
actually matters.

Obviously one case not covered here is when the mode
itself is embedded in a larger structure and the whole
structure is copied. But if we are careful when copying
into modes embedded in structures I think we can be a
little more reassured that bogus list heads haven't been
propagated in.

drm/vc4: crtc: Fix runtime_pm reference counting
At boot on the BCM2711, if the HDMI controllers are running, the CRTC
driver will disable itself and its associated HDMI controller to work
around a hardware bug that would leave some pixels stuck in a FIFO.

In order to avoid that issue, we need to run some operations in lockstep
between the CRTC and HDMI controller, and we need to make sure the HDMI
controller will be powered properly.

However, since we haven't enabled it through KMS, the runtime_pm state
is off at this point so we need to make sure the device is powered
through pm_runtime_resume_and_get, and once the operations are complete,
we call pm_runtime_put.

However, the HDMI controller will do that itself in its
post_crtc_powerdown, which means we'll end up calling pm_runtime_put for
a single pm_runtime_get, throwing the reference counting off. Let's
remove the pm_runtime_put call in the CRTC code in order to have the
proper counting.
