media: camss: vfe: Format conversion support using PIX interface
Use VFE PIX input interface and do format conversion in VFE. Supported input format is UYVY (single plane YUV 4:2:2) and its different sample order variations. Supported output formats are: - NV12/NV21 (two plane YUV 4:2:0) - NV16/NV61 (two plane YUV 4:2:2) Signed-off-by: Todor Tomov <todor.tomov@linaro.org> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
