There is no reason for a user to select this or not directly - it should

Hi Konrad.
Thanks for the new panel binding.
But you need to redo this as panel bindings today must be in DT Schema

Please see other bindings in the same dir for examples.

container_of is never null, so the null check on pdd is unnecessary.
If the null check is removed, function kfd_procfs_show()
will always return before reaching "return 0", hence
such return is logically dead. So, remove it, as well.

How do you think about a wording variant like the following?

The devm_gen_pool_create() function returns ERR_PTR() on error, it

Sometimes it's not okay to use SIMD registers, the conditions for which
have changed subtly from kernel release to kernel release. Usually the
pattern is to check for may_use_simd() and then fallback to using
something slower in the unlikely case SIMD registers aren't available.
So, this patch

How do you think about a wording variant like the following?

Hi,
You have first to split this patch in several patches and add relevant
people in TO (using get_maintainer script) for each patch. Quickly,
you should at least have 4 patches (DT, clock driver, spi driver and drm
). Then review will be more efficient.

The ANX7625 is an ultra-low power 4K Mobile HD Transmitter designed
for portable device. It converts MIPI DSI/DPI to DisplayPort 1.3 4K.
The ANX7625 can support both USB Type-C PD feature and MIPI DSI/DPI
to DP feature. This driver only enabled MIPI DSI/DPI to DP feature.

On i.MX8MM there is an interrupt getting triggered immediately after
requesting the IRQ, which leads to a stall as the handler accesses
the GPU registers whithout the clock being enabled.
Enabling the clocks briefly seems to clear the IRQ state, so we do
this before
