There are some differences between the schematics and the official firmware DTS [1]. So based on these additional information the following has been changed: * use consistent "CAM_GPIO1" for camera LED * use consistent "CAM_GPIO0" for camera shutdown * add "USB_LIMIT" for USB current limit (0=600mA, 1=1200mA) [1] - https://github.com/raspberrypi/firmware/blob/master/extra/dt-blob.dts Signed-off-by: Stefan Wahren <stefan.wahren@i2se.com> Signed-off-by: Eric Anholt <eric@anholt.net>
