[PATCH 2/2] drm/exynos: mixer: document YCbCr magic numbers

2017-03-03 Thread Tobias Jakobi
The output stage of the mixer uses YCbCr for the internal computations, which is the reason that some registers take YCbCr related data as input. In particular this applies to MXR_BG_COLOR{0,1,2} and MXR_CM_COEFF_{Y,CB,CR}. Document the formatting of the data which we write to these registers. Wh
