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 Comment under v8 no longer applicable v11: Addressed review comments from Shashank Sharma v12: Adding Reviewed By from Shashank Sharma v13: Addressed review comments from Juha-Pekka Heikkila "NV12 not to be supported by SKL" v14: Addressed review comments from Maarten. Add checks for fb width height for NV12 and fail the fb creation if check fails. Added reviewed by from Juha-Pekka Heikkila v15: Rebased the series v16: Setting the minimum value during fb creating to 16 as per Bspec for NV12. Earlier minimum was expected to be > 16. Now changed it to >=16.
