Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote).

Guidelines for Video4Linux pixel format 4CCs
|
|
============================================
|
|
|
|
Guidelines for Video4Linux 4CC codes defined using v4l2_fourcc() are
|
|
specified in this document. First of the characters defines the nature of
|
|
the pixel format, compression and colour space. The interpretation of the
|
|
other three characters depends on the first one.
|
|
|
|
Existing 4CCs may not obey these guidelines.

|
Raw bayer
|
|
---------
|
|
|
|
The following first characters are used by raw bayer formats:
|
|
|
|
- B: raw bayer, uncompressed
|
|
- b: raw bayer, DPCM compressed
|
|
- a: A-law compressed
|
|
- u: u-law compressed
|
|
|
|
2nd character: pixel order
|
|
|
|
- B: BGGR
|
|
- G: GBRG
|
|
- g: GRBG
|
|
- R: RGGB
|
|
|
|
3rd character: uncompressed bits-per-pixel 0--9, A--
|
|
|
|
4th character: compressed bits-per-pixel 0--9, A--
