Subject: [PATCH] drm/mediatek: Clarify/finish documentation for some driver structures
The documentation for some of the driver structures in mediatek-drm
was set to be kerneldoc but some code additions didn't actually update
the comments accordingly and this caused triggering some warnings.
Add comments for the remaining undocumented entries; while at it, also
clarify some acronyms for various display HW blocks and fix some comment
blocks to actually get parsed as kerneldoc.
