more devices, and we added some optional rust code to create QR codes

A fairly big update at this time, both in core and driver sides.
The core received rewrites in PCM buffer allocation handling and
locking optimizations, PCM rate updates followed by lots of cleanups.
In ASoC side, the legacy Intel drivers have been deprecated by AVS
drivers which leaded to the significant amount of code reduction.
SoundWire driver updates and other cleanups contributed more code
reduction, too.
USB-audio driver received a large cleanup of its big quirk table, and
the old snd_print*() API usages in many legacy drivers are replaced
with the standard print API.
Here are some highlights:
Core:
- More optimized locking in ALSA control code
- Rewrites of memalloc helpers for better DMA API usage
- Drop of obsoleted vmalloc PCM buffer helper API
- Continued MIDI2 UMP updates
- Support of a new user-space driven timer instance
- Update for more PCM support rates and cleanups
- Xrun counter report in the proc files
ASoC:
- Continued simplification and cleanup works for ASoC
- Extensive cleanups and refactoring of the Soundwire drivers
- Removal of Intel machine support obsoleted by the AVS driver
- Lots of DT schema conversions
- Machine support for many AMD and Intel x86 platforms
- Support for AMD ACP 7.1, Mediatek MT6367 and MT8365, Realtek RTL1320
SoundWire and rev C, and Texas Instruments TAS2563
USB-audio:
- Add support of multiple control interfaces
- A large rewrite of quirk table with macros
- Support for RME Digiface USB
HD-audio:
- Cleanup of quirk code for Samsung Galaxy laptops
- Clean up of detection of Cirrus codecs
- C-Media CM9825 HD-audio codec support
Others:
- Rewrites to standard print API in a lot of legacy drivers

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.

Signed-off-by: Maxime Ripard <mripard@kernel.org>
The dw-hdmi drm bridge driver is the only one who still uses the ALSA
vmalloc helper API functions. A previous attempt to change the way of
buffer management wasn't taken for this legacy stuff, as we had little
chance for test and some risk of major breaking.
Instead, this patch moves the vmalloc buffer stuff into the dw-hdmi
driver code itself, so that we can drop them from ALSA core code
afterwards.
There should be no functional changes.

Using the correct bit helps. The documentation specifies bit 0 in both
registers to be controlling polarity of dpi_vsync_input and
dpi_hsync_input polarity. Bit 1 is reserved, and should therefore not be
set.
Tested with panel that requires active high vsync and hsync.

There's no need to get the length of an DT array property before
parsing the array. of_property_read_variable_u8_array() takes a minimum
and maximum length and returns the actual length (or error code).
This is part of a larger effort to remove callers of of_get_property()
and similar functions. of_get_property() leaks the DT property data
pointer which is a problem for dynamically allocated nodes which may
be freed.

Make use of devm_clk_get_enabled() to replace devm_clk_get() and
clk_prepare_enable() for isfr and iahb clocks, and drop the now
unnecessary calls to clk_disable_unprepare().
Similarly, use devm_clk_get_optional_enabled() helper for cec clock,
which additionally allows to remove the -ENOENT test.
Moreover, the clock related members of struct dw_hdmi are not required
anymore, hence drop them.

If the bridge is attached with the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag set,
this driver won't initialize a connector and hence display mode won't be
validated in drm_connector_helper_funcs::mode_valid(). So, move the mode
validation from drm_connector_helper_funcs::mode_valid() to
drm_bridge_funcs::mode_valid(), because the mode validation is always done
for the bridge.

Enable the transmission of an EoTp (end of transmission packet) by

that can be disabled by a dsi mod_flag if needed.
EoTp signals the end of an HS transmission, this adds overall robustness
at protocol level at the expense of an increased overhead.

In the process of adding support for shared IRQ pins, a scenario
was accidentally created where adv7511_irq_process returned
prematurely causing the EDID to fail randomly.
Since the interrupt handler is broken up into two main helper functions,
update both of them to treat the helper functions as IRQ handlers. These
IRQ routines process their respective tasks as before, but if they
determine that actual work was done, mark the respective IRQ status
accordingly, and delay the check until everything has been processed.
This should guarantee the helper functions don't return prematurely
while still returning proper values of either IRQ_HANDLED or IRQ_NONE.

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.

The PLL will be reconfigured later, which may cause it to go out of lock
anyway, so there is no point in waiting for the PLL to lock here. Instead
we can continue execution of the link setup, which will properly set the
PLL parameters and will wait for the PLL to lock at the appropriate times.

This check is way too late in the DP enable flow. The PLL must be
locked much earlier, before any link training can happen. If the
PLL is unlocked at that point in time there is something seriously
wrong in the enable flow.

Make sure the controller is in a basic working state after runtime
resume. Keep the analog function enable in the mode set path as this
enables parts of the PHY that are only required to be powered when
there is a data stream being sent out.

Platform and PHY power isn't only required when the actual display data
stream is active, but may be required earlier to support AUX channel
transactions. Move them into the runtime PM calls, so they are properly
managed whenever various other parts of the driver need them to be active.

There is no reason to enable the controller clock in driver probe, as
there is no HW initialization done in this function. Instead rely on
either runtime PM to handle the controller clock or statically enable
it in the driver bind routine, after which real hardware access is
required to work.

The only information in the datasheet regarding this divider is a note
in SYS_PLLPARAM register documentation which states that when LSCLK is
270 MHz, LSCLK_DIV should be 1. What should LSCLK_DIV be set to when
LSCLK is 162 MHz (for DP 1.62G mode) is unclear, but empirical test
confirms using LSCLK_DIV 1 has no adverse effects either. In the worst
case, the internal TC358767 clock would run faster.

This line_pixel_subtract is no longer needed now that the bridge can
request and obtain specific pixel clock on input to the bridge, with
clock frequency that matches the Pixel PLL frequency.
The line_pixel_subtract is now always 0, so drop it entirely.
The line_pixel_subtract was not reliable as it never worked when the
Pixel PLL and input clock were off just so that the required amount
of pixels to subtract would not be whole integer.

This is a preparatory patch for further rework, where tc_pxl_pll_calc()
will also be used to find out the exact clock frequency generated by the
Pixel PLL. This frequency will be used as adjusted_mode clock frequency
and passed down the display pipeline to obtain exactly this frequency
on input into this bridge.

Currently, mode_valid is defined only in drm_connector_helper_funcs.
When the bridge is attached with the 'DRM_BRIDGE_ATTACH_NO_CONNECTOR'
flag, the connector is not initialized, and so is the mode_valid
hook under connector helper funcs.
It also returns MODE_OK for all modes without actually checking the
modes.
So move the mode_valid hook to drm_bridge_funcs with proper clock
checks for maximum and minimum pixel clock supported by the bridge.

The VFP, HBP, and HSA are divided between the available lanes if
there is more than one lane. For certain timings and lane
configurations, the HFP may not be evenly divisible. If the HFP
is rounded down, it ends up being too small which can cause some
monitors to not sync properly. In these instances, adjust htotal
and hsync to round the HFP up, and recalculate the htotal.
This allows 720P-60 to operation on an i.MX8MP with a four-lane
configuration.
