+From 05a5bc2bfa028885c844ccc2263029b5db9160b4 Mon Sep 17 00:00:00 2001
+From: Naushir Patuck <naush@raspberrypi.com>
+Date: Thu, 23 Apr 2020 10:17:37 +0100
+Subject: [PATCH] staging: vc04_services: ISP: Add a more complex ISP
+ processing component
+
+Driver for the BCM2835 ISP hardware block. This driver uses the MMAL
+component to program the ISP hardware through the VC firmware.
+
+The ISP component can produce two video stream outputs, and Bayer
+image statistics. This can't be encompassed in a simple V4L2
+M2M device, so create a new device that registers 4 video nodes.
+
+Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
