This really needs to be expanded.
Ideally this should reference the precise specification of this format if
available.
It certainly should explain which HW blocks of the mediatek SoC use this
format, it should explain that is it meant as an opaque intermediate format
between those blocks.
If you have some characteristics (i.e. is it lossy or lossless
compression, I
presume it's lossless), then that will be useful to add as well.
We like to have as much information about formats as possible.

Hans
