From: Hans Verkuil <hans.verkuil@xxxxxxxxx>
The HDMI standard defines a Content Type field in the AVI InfoFrame that
can tell the receiver what sort of video is being transferred. Based on
that information the receiver can choose to optimize for that content type.
A practical example is that if the content type is set to 'Game' then the
TV might configure itself to a low-latency mode.
But this requires that applications can get/set the content type, and that's
what this patch series does: it adds new content type controls and
implements it in the adv7511 HDMI transmitter and adv7604/adv7842 receivers.
Regards,
Hans
