YUV422 cannot be used, referring to the HDMI 1.3 Specification.

This specification, in its section 6.2.4, indeed states:

  For each supported Deep Color mode, RGB 4:4:4 shall be supported and
  optionally YCBCR 4:4:4 may be supported.

  YCBCR 4:2:2 is not permitted for any Deep Color mode.

  For each supported Deep Color mode, RGB 4:4:4 shall be supported and
  optionally YCBCR 4:4:4 may be supported.

  of the Deep Color modes described in section 6.5.2 and 6.5.3.

This means that, even though YUV422 can be used with 12 bit per color,
it shouldn't be treated as a deep color mode.

This deviates from the interpretation of the code and comment, so let's

next page in physical memory and this is where the behaviour causes a
