[PATCH v3 14/23] camss: vfe: Format conversion support using PIX interface

From: Todor Tomov
Date: Mon Jul 17 2017 - 06:40:12 EST

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)
