[PATCH v2] drm/msm/dpu: add support for 4:2:2 planar YCbCr plane formats

[Dmitry Baryshkov]

From: Dmitry Baryshkov <dmitry.baryshkov at linaro.org>

The DPU driver provides support for 4:2:0 planar YCbCr plane formats.
Extend it to also support 4:2:2 planar formats.

Changes in v2:
- Dropped 4:4:4 formats, they require higher clocks.
- Link to v1: https://lore.kernel.org/r/20240222-fd-dpu-yv16-yv24-v1-1-4aa833cdc641@linaro.org
