Subject: [PATCH] ARM: bcm2835: Fix names for the Raspberry Pi GPIO lines
|
||
|
|
|
||
|
|
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)
|
||
|
|
