Couple of general comments about the LSPCON stuff.
a) we need infoframe readout support
b) we need to stop sending infoframes to DVI sinks
c) we need to figure out how to disable the AVI infoframe
once enabled (if it doesn't get automagically disabled
when do a modeset), because otherwise when we switch
displays from HDMI to DVI we will still send the infoframe
to the DVI sink
I think those should be fixed first before we add more
infoframes to the mix.
Also if we use the SDP stuff for the HDR infoframe we should
just integrate it properly with the already existing DP HDR
metadata stuff. And we need to add readout support for that.
