The video sprites support various video surface formats natively and can
handle scaling as well. So add support for them using the new DRM core
sprite support functions.
v2: use drm specific fourcc header and defines
v3: address Daniel's comments:
- don't take struct mutex around register access (only needed for
regs in the GT power well)
- don't hold struct mutex across vblank waits
- fix up update_plane API (pass obj instead of GTT offset)
- add interlaced defines for sprite regs
- drop unnecessary 'reg' variables
- comment double buffered reg flushing
Also fix w/h confusion when writing the scaling reg.
v4: more fixes, address more comments from Daniel, and include Hai's fix
- prevent divide by zero in scaling calculation (Hai Lan)
- update to Ville's new DRM_FORMAT_* types
- fix sprite watermark handling (calc based on CRTC size, separate
from normal display wm)
- remove private refcounts now that the fb cleanups handles things
v5: add linear surface support
v6: remove color key clearing & setting from update_plane
For this version, I tested DPMS since it came up in the last review;
DPMS off/on works ok when a video player is working under X, but for
power saving we'll probably want to do something smarter. I'll leave
that for a separate patch on top. Likewise with the refcounting/fb
layer handling, which are really separate cleanups.
