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).
|
|
