Merge tag 'media/v5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- some rework at the uAPI pixel format docs
- the smiapp driver has started to gain support for MIPI CSS camera
sensors and was renamed
- two new sensor drivers: ov02a10 and ov9734
- Meson gained a driver for the 2D acceleration unit
- Rockchip rkisp1 driver was promoted from staging
- Cedrus driver gained support for VP8
- two new remote controller keymaps were added
- the usual set of fixes cleanups and driver improvements

This is a planar format similar to the -4:2:2 planar format except with half as many chroma. The three -components are separated into three sub-images or planes. The Y plane is -first. The Y plane has one byte per pixel. The Cb plane immediately -follows the Y plane in memory. The Cb plane is ¼ the width of the Y -plane (and of the image). Each Cb belongs to 4 pixels all on the same -row. For example, Cb\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`, -Y'\ :sub:`02` and Y'\ :sub:`03`. Following the Cb plane is the Cr plane, -just like the Cb plane. - -If the Y plane has pad bytes after each row, then the Cr and Cb planes -have ¼ as many pad bytes after their rows.
