Also, I think flag DRM_MODE_FLAG_DBLCLK does not sound correct for
them, so we would need to create flags:
- DRM_MODE_FLAG_PR_1_to_10
- DRM_MODE_FLAG_PR_1_or_2
- DRM_MOD

These modes you're talking about (10-15, 25-30, 35-38), ar

The CEA spec has a bunch of very peculiar modes. For backwards
compatibility it specifies a bunch of modes that are suitable to
display old SD TV content. But these modes have such low pixel clocks
that pixels need to be doubled to reach the minimal clock of the HDMI
interface.

The CEA has a bunch of very peculiar modes. For backwards
compatibility is specifies a bunch of resulting that are suitable to
display old SD TV content. But these modes have such low pixel clocks
that pixels need to be double to reach the minimal clock of the HDMI
interface.
