Hi,
This series adds support for programming the SPD and vendor infoframes.
It also adds support for pixel repeated modes - we were not rejecting
these modes, but we also didn't have the implementation to support
them. As their implementation is simple, add it rather than rejecting
the modes.
Support is also added for the bridge timing information, that upstream
components may wish to use to adjust their output appropriately.
Lastly, rather than merely passing through the full-range RGB from the
CRTC, adapt the RGB range to the capabilities of the display and the
default range for the mode. This means that if the display does not
support the Q bit in the video infoframe, and the mode is defined to
have limited range RGB, we will compress the output RGB range to
limited range.
Tested on 4.20 with a Panasonic TV.
