Subject: [PATCH V2 1/2] ARM: bcm2835: Fix names for the Raspberry Pi GPIO lines
Date: Wed, 16 Nov 2016 17:52:06 +0000	[thread overview]
Message-ID: <1479318727-9425-2-git-send-email-stefan.wahren@i2se.com> (raw)
In-Reply-To: <1479318727-9425-1-git-send-email-stefan.wahren@i2se.com>

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
