   4 Subject: [PATCH] ARM: bcm2835: Fix names for the Raspberry Pi GPIO lines
   5
   6 There are some differences between the schematics and the official firmware
   7 DTS [1]. So based on these additional information the following has been
   8 changed:
   9
  10 * use consistent "CAM_GPIO1" for camera LED
  11 * use consistent "CAM_GPIO0" for camera shutdown
  12 * add "USB_LIMIT" for USB current limit (0=600mA, 1=1200mA)
