ASoC: Fixes for v6.16
Two patches here, one quirk for an AMD system and a fix for an issue on
remove of the AVS driver.
Before each I2C transfer using DMA, the I2C buffer is DMA'pped to make
sure the memory buffer is DMA'able. This is handle in the function
`stm32_i2c_prep_dma_xfer()`.
If the transfer fails for any reason the I2C buffer must be unmap.
Use the dma_callback to factorize the code and fix this issue.
Note that the `stm32f7_i2c_dma_callback()` is now called in case of DMA
transfer success and error and that the `complete()` on the dma_complete
completion structure is done inconditionnally in case of transfer
success or error as well as the `dmaengine_terminate_async()`.
This is allowed as a `complete()` in case transfer error has no effect
as well as a `dmaengine_terminate_async()` on a transfer success.
Also fix the unneeded cast and remove not more needed variables.

In commit 7d3c7d2a29 ("media: i2c: Add a camera sensor top level menu")
a top level menu was added for sensor drivers so that all sensor drivers
would depend on I2C and so that MEDIA_CONTROLLER, V4L2_FWNODE and
VIDEO_V4L2_SUBDEV_API would be automatically selected for all sensor
drivers.
All lens drivers must depend on I2C and VIDEO_DEV and must select
MEDIA_CONTROLLER, V4L2_FWNODE and VIDEO_V4L2_SUBDEV_API and most already
do, but e.g. VIDEO_V4L2_SUBDEV_API is not consistenly selected.
Change the "Lens drivers" menu into a menuconfig option with
the necessary depends and selects. This ensures that these options are
depended on / selected consistently and simplifies the Kconfig snippets
for the various lens voice coil drivers.

probe() requests the reset GPIO to be set to high when getting it.
Immeditately after this hi556_resume() is called and sets the GPIO low.
If the GPIO was low before requesting it this will result in the GPIO
only very briefly spiking high and the sensor not being properly reset.
The same problem also happens on back to back runtime suspend + resume.
Fix this by adding a sleep of 2 ms in hi556_resume() before setting
the GPIO low (if there is a reset GPIO).
The final sleep is kept unconditional, because if there is e.g. no reset
GPIO but a controllable clock then the sensor also needs some time after
enabling the clock.

User-space can provide cache hints to enable software managed cache

This is tested on AM62px with yavta capture by passing
V4L2_MEMORY_FLAG_NON_COHERENT while using VIDIOC_REQBUFS and
V4L2_BUF_FLAG_NO_CACHE_CLEAN while using VIDIOC_QBUF and ~5x reduction in

The object is potentially already gone after the drm_gem_object_put().
In general the object should be fully constructed before calling
drm_gem_handle_create(), except the debugfs tracking uses a separate
lock and list and separate flag to denotate whether the object is
actually initialized.
Since I'm touching this all anyway simplify this by only adding the
object to the debugfs when it's ready for that, which allows us to
delete that separate flag. panthor_gem_debugfs_bo_rm() already checks
whether we've actually been added to the list or this is some error

Old revisions of the ROCK 4D board have a dedicated crystal to
supply the RTL8211F PHY's 25MHz clock input. At least some newer
revisions instead use REFCLKO25M_GMAC0_OUT. The DT already has
this half-prepared, but there are some issues:
1. The DT relies on auto-selecting the right PHY driver, which
requires that it works good enough to read the ID registers.
This does not work without the clock, which is handled by
the PHY driver. By updating the compatible to contain the
RTL8211F IDs, so that the operating system can choose the
right PHY driver without relying on a pre-powered PHY.
2. Despite the name REFCLKO25M_GMAC0_OUT could also provide a
different frequency, so ensure it is explicitly set to 25
MHz as expected by the PHY.
3. While at it switch from deprecated "enable-gpio" to standard
"enable-gpios".

The snd_compr_ioctl() ignores the upper 24 bits of the ioctl command
number and only compares the number of the ioctl command, which can
cause unintended behavior if an application tries to use an unsupprted
command that happens to have the same _IOC_NR() value.
Remove the truncation to the low bits and compare the entire ioctl
command code like every other driver does.
