This patch adds NV12 as supported format
to intel_framebuffer_init and performs various checks.
v2:
-Fix an issue in checks added (Chandra Konduru)
v3: rebased (me)
v4: Review comments by Ville addressed
Added platform check for NV12 in intel_framebuffer_init
Removed offset checks for NV12 case
v5: Addressed review comments by Clinton A Taylor
This NV12 support only correctly works on SKL.
Plane color space conversion is different on GLK and later platforms
causing the colors to display incorrectly.
Ville's plane color space property patch series
in review will fix this issue.
- Restricted the NV12 case in intel_framebuffer_init to
SKL and BXT only.
v6: Rebased (me)
v7: Addressed review comments by Ville
Restricting the NV12 to BXT for now.
v8: Rebased (me)
Restricting the NV12 changes to BXT and KBL for now.
v9: Rebased (me)
v10: NV12 supported by all GEN >= 9.
Making this change in intel_framebuffer_init. This is
part of addressing Maarten's review comments.
Comment under v8 no longer applicable
