-From bfa002eac168328b599ea70ed81667c03b16cb7e Mon Sep 17 00:00:00 2001
-From: David Plowman <david.plowman@raspberrypi.com>
-Date: Tue, 12 Jan 2021 13:55:39 +0000
-Subject: [PATCH] bcm2835-isp: Allow formats with different colour
- spaces.
-
-Each supported format now includes a mask showing the allowed colour
-spaces, as well as a default colour space for when one was not
-specified.
-
-Additionally we translate the colour space to mmal format and pass it
-over to the VideoCore.
