[PATCH v2] drm/malidp: Fix writeback in NV12

2018-08-22 Thread Alexandru Gheorghe
When we want to writeback to memory in NV12 format we need to program the RGB2YUV coefficients. Currently, we don't program the coefficients and NV12 doesn't work at all. This patchset fixes that by programming a sane default(bt709, limited range) as rgb2yuv coefficients. In the long run,
