Subject: drm/dsc: Define the DSC 1.1 and 1.2 Line Buffer depth constants
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f25310c7360b1825ee25858b68685c94abaa11a3;p=linux.git

drm/dsc: Define the DSC 1.1 and 1.2 Line Buffer depth constants

DSC specification defines linebuf_depth which contains the
line buffer bit depth used to generate the bitstream.
These values are defined as per Table 4.1 in DSC 1.2 spec

v2 (From Manasi):
* Rename as MAX_LINEBUF_DEPTH for DSC 1.1 and DSC 1.2
