Commit Message

Shankar, Uma March 11, 2019, 3:57 a.m.
CEA 861.3 spec adds colorimetry data block for HDMI.
Parsing the block to get the colorimetry data from
panel.

v2: Rebase

v3: No Change

v4: Addressed Shashank's review comments. Updated
colorimetry field to 16 bit as DCI-P3 got added
in CEA 861-G spec, as pointed out by Shashank.

This means we are setting the 15th bit for DCI-P3 then there is a gap of 7 bits, and then there are other bits. Do we want to make DCI-P3 as bit 8 ? Anyways this can be differed for a discussion later.

This is at 8th position only.  We are shifting the db[3] which is 8 bit by 1 and keeping the 7th bit (DCI-P3)
at the 8th position (if we count from 0).

My bad,  its 8th bit only.

If those above alignment problems are checked already, feel free to use
