From 39c4b77533bee8d88d2f4c9be9463041ec1dd483 Mon Sep 17 00:00:00 2001
From: Dave Stevenson <dave.stevenson@raspberrypi.org>
Date: Wed, 13 Feb 2019 12:33:29 +0000
Subject: [PATCH] staging: mmal_vchiq: Add in the Bayer encoding
formats
The list of formats was copied before Bayer support was added.
The ISP supports Bayer and is being supported by the bcm2835_codec
driver, so add in the encodings for them.
