From: Hans Verkuil Date: Mon, 9 Mar 2015 15:03:52 +0000 (-0300) Subject: [media] vivid: add support for single buffer planar formats X-Git-Tag: v4.1-rc1~59^2~1^2~163 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=ddcaee9dd4c00174db8ddf913c87ddf3773c446e;p=linux.git [media] vivid: add support for single buffer planar formats Make vivid aware of the difference of planes and buffers. Note that this does not yet add support for hor/vert downsampled formats.
