VESA has developed an industry standard Display Stream Compression(DSC)
for interoperable, visually lossless compression over display links to
address the needs for higher resolution displays.
This patch series enables DSC on Gen 10 eDP and Gen 11 eDP/DP panels.
This implementation is based on VESA DP 1.4 and DSC specifications.
These patches have been validated on 1080p eDP 1.4 panel with DSC support
and FPGA based DP 1.4 sink device.
