[RFC/PATCH 0/2] Clarify display info PIXDATA bus flags

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

 



Hello,

This patch series attemps at clarifying usage of the
DRM_BUS_FLAG_PIXDATA_(POS|NEG)EDGE flags. It results from a discussion
on the mailing list available at [1].

The problem being discussed was confusion around how the
DRM_BUS_FLAG_PIXDATA_POSEDGE and DRM_BUS_FLAG_PIXDATA_NEGEDGE flags
could be interpreted (and are interpreted now by drivers). Patch 1/2
introduces new, more explicit flags, and explains the rationale. Patch
2/2 then updates the drivers to use the new flags.
