[PATCH v5 1/3] dt-bindings: pinctrl: bcm2835-gpio: Add generic pinctrl support

From: Matheus Castello
Date: Wed Apr 11 2018 - 01:21:00 EST


Added generic pin configuration and multiplexing support,
and should be preferred than brcm legacy one.

- brcm,pins: An array of cells. Each cell contains the ID of a pin. Valid IDs
are the integer GPIO IDs; 0==GPIO0, 1==GPIO1, ... 53==GPIO53.
