[Intel-gfx] [PATCH 01/11] drm/i915: sprite support for ValleyView v3
Jesse Barnes
jbarnes at virtuousgeek.org
Thu Mar 28 17:55:37 CET 2013
No constant alpha yet though, that needs a new ioctl and/or property to
get/set.
v2: use drm_plane_format_cpp (Ville)
fix up vlv_disable_plane, remove IVB bits (Ville)
remove error path rework (Ville)
fix component order confusion (Ville)
clean up platform init (Ville)
use compute_offset_xtiled (Ville)
v3: fix up more format confusion (Ville)
update to new page offset function (Ville)
