  The TDA19971/73 are HDMI video receivers.

  The TDA19971 Video port output pins can be used as follows:
   - RGB 8bit per color (24 bits total): R[11:4] B[11:4] G[11:4]
   - YUV444 8bit per color (24 bits total): Y[11:4] Cr[11:4] Cb[11:4]
   - YUV422 semi-planar 8bit per component (16 bits total): Y[11:4] CbCr[11:4]
   - YUV422 semi-planar 10bit per component (20 bits total): Y[11:2] CbCr[11:2]
   - YUV422 semi-planar 12bit per component (24 bits total): - Y[11:0] CbCr[11:0]
   - YUV422 BT656 8bit per component (8 bits total): YCbCr[11:4] (2-cycles)
   - YUV422 BT656 10bit per component (10 bits total): YCbCr[11:2] (2-cycles)
   - YUV422 BT656 12bit per component (12 bits total): YCbCr[11:0] (2-cycles)

  The TDA19973 Video port output pins can be used as follows:
   - RGB 12bit per color (36 bits total): R[11:0] B[11:0] G[11:0]
   - YUV444 12bit per color (36 bits total): Y[11:0] Cb[11:0] Cr[11:0]
   - YUV422 semi-planar 12bit per component (24 bits total): Y[11:0] CbCr[11:0]
   - YUV422 BT656 12bit per component (12 bits total): YCbCr[11:0] (2-cycles)

  The Video port output pins are mapped via 4-bit 'pin groups' allowing
  for a variety of connection possibilities including swapping pin order within
  pin groups. The video_portcfg device-tree property consists of register mapping
  pairs which map a chip-specific VP output register to a 4-bit pin group. If
  the pin group needs to be bit-swapped you can use the *_S pin-group defines.
