+From 7782ca4dcb10a244ae476126220890a0843c439e Mon Sep 17 00:00:00 2001

+Subject: [PATCH] dt: Add a camera regulator node to all downstream Pi
+ platforms
+
+The current firmware fixup of camera sensor overlays is not
+particularly nice, and it stops you being able to load them
+dynamically.
+It's also incompatible with creating a simple DT that can be
+loaded for both CAM1 and CAM0 on a CM as they would both
+try to claim the one GPIO.
+
+Almost all sensors have a hook of some form for a regulator, so
+it's relatively straightforward to convert them all to use a
+fixed regulator with GPIO control.
+
+Add a fixed regulator node for each platform with the GPIO
+correctly configured for the camera shutdown line. (The LED line
+is ignored).
