+From c3ea5332de058ee7b9139133f2f8103b6dff2478 Mon Sep 17 00:00:00 2001
+From: Dave Stevenson <dave.stevenson@raspberrypi.org>
+Date: Wed, 31 Oct 2018 15:01:59 +0000
+Subject: [PATCH] arm: dt: Add DT overlays for ADV7282M, OV5647, and
+ TC358743
+
+DT overlays to setup the above devices via i2c_arm and csi1.
+(This currently does not use the i2c-mux-pinctrl driver to
+dynamically switch the pinctrl)
+
+tc358743 is tc358743 running at a default link frequency
+of 972Mbit/s. This allows up to 1080P50 UYVY on 2 lanes.
+There is a parameter to allow changing the link frequency,
+but the only values supported by the driver are 297000000
+for 594Mbit/s, and 486000000 for 972Mbit/s.
+There is also a parameter to enable 4 lane mode (only
+relevant to Compute Module (1 or 3) csi1).
+
+tc358743-audio overlay enables I2S audio from the TC358743
+to the Pi (SD to GPIO20, SCK to GPIO18, WFS to GPIO19).
+
+ADV7282M is the Analog Devices analogue video to CSI bridge
+chip.
+
+OV5647 is the Pi V1.3 camera module. Currently the driver only
+supports VGA 8bit Bayer and very few controls.
