33.4.18 RGB to YCbCr 4:2:2 CSC Coefficient0 Register
HW_LCDIF_CSC_COEFF0 register provides overall control over color space conversion
from RGB to 4:2:2 YCbCr. The equations for the conversion are given by:
Y = C0*R + C1*G + C2*B + Y_offset
Cb= C3*R + C4*G + C5*B + CbCr_offset
Cr= C6*R + C7*G + C8*B + CbCr_offset
This register carries programming information about RGB to YCbCr 4:2:2 CSC.

Value of Y component of filler data
Value of CB component of filler data
Value of CR component of filler data.
Number of active video samples that have to be filled with the filler data in the front and back portions of the
active horizontal interval. Must be a multiple of 4. This field will have to be programmed if the input frame
has less than 720 pixels per line.
