Subject: media: cedrus: Add support for additional output formats
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=193cd0fd5a6055b88a3b2860c43a647362f9e7c4;p=thirdparty%2Flinux.git

media: cedrus: Add support for additional output formats

If VPU supports untiled output, it actually supports several different
YUV 4:2:0 layouts, namely NV12, NV21, YUV420 and YVU420.

Add support for all of them.
