From b2bb3d822f2c9e27236ea32bc5ef18a9f22c8a80 Mon Sep 17 00:00:00 2001 From: Nikhil Devshatwar Date: Mon, 7 Oct 2019 12:09:54 -0300 Subject: [PATCH] media: ti-vpe: Add support for NV21 format In NV21 format, the chroma plane is written to memory such that the U and V components are swapped for NV12. Create a new entry in the VPDMA formats to describe the correct data types used in the data descriptors. Update all checks for NV12 and add NV21 there as well. Add support for V4L2_PIX_FMT_NV21 format for both capture and output streams.
