Subject: media: staging: rkisp1: cap: enable RGB capture format with YUV media
bus
Author: Dafna Hirschfeld <dafna.hirschf...@collabora.com>
Date: Sun Apr 12 14:05:04 2020 +0200
In selfpath, RGB capture formats are received in the sink pad as YUV
and are converted to RGB only when writing to memory. So the validation
function should accept YUV bus formats with RGB capture encoding.
