[PATCH v2 0/4] DRM helpers for Display Stream Compression PPS infoframes

[Manasi Navare]

VESA Display Stream Compression is a specification for visually losless
video compression over display links. The DSC standard also defines
a picture parameter set (PPS) which encoder must communicate to decoders.
This is done by encapsulating PPS header and payload bytes in an infoframe
that can be sent to the display sink using secondary data packets
as defined in DP 1.4 spec.

This patch series creates a new files drm_dsc.h and drm_dsc.c
which define all the DSC related structures and helpers that
can be called by drivers to form DSC PPS infoframes before
enabling Display Stream compression on eDP/DP/MIPI

v2:
*This is a v2 of the original patch series which adds kernel-doc
hooks for the new dsc files in drm-kms-helpers.rst. (Daniel Vetter)
