Hi,
This is the second round of RFC for adding a bunch of new YUV formats for Mali/AFBC. I've included a proper AFBC documentation file too, for posterity.
Some of the new formats don't have an integer number of bytes-per-pixel, so I've added a bpp field to drm_format_info (patch 1), keen to hear thoughts on that.
These three patches don't make a huge amount of sense in isolation, so we'll pull them into a more comprehensive series for AFBC support to merge them later.
Thanks, -Brian
