Do we really need to make this stuff visible to userspace?
And there's no documentation to explain any of it.

DRM_MODE_FLAG_PDATEN and DRM_MODE_FLAG_NDATEN were meant to represent the data enable polarity.

DRM_MODE_FLAG_PPIXDATEDGE and DRM_MODE_FLAG_NPIXDATEDGE were meant to represent the clock polarity.

What would you recommend to represent theses polarities?

Denis.
