Subject: [RFC PATCH v2 0/3] Groundwork for AFBC YUV formats
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
