[PATCH RFC v3 30/37] drm/rockchip: inno_hdmi: Switch to infoframe type

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The inno_hdmi driver relies on its own internal infoframe type matching
the hardware.

This works fine, but in order to make further reworks easier, let's
switch to the HDMI spec definition of those types.
