This gets us in sync with dts from kernel 4.11. Two patches were already backported earlier. I decided to use 03x prefix as it's kind of similar to the 3xx prefix: 3xx - architecture specific patches It isn't any documented or strict rule though. We don't need to stick to it if we hit any problems. Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Acked-by: Álvaro Fernández Rojas <noltari@gmail.com>

Subject: [PATCH] ARM: bcm2835: Add names for the RPi Zero GPIO lines
|
|
|
|
This adds the GPIO names for the Raspberry Pi Zero. The GPIO lines
|
|
of the RPi Zero are almost identical to the Model A+ except:
|
|
|
|
* GPIO 35, 38, 40 and 45 are not connected
|
|
* Status LED is active low
