The BCM2835 pin configuration and multiplexing supports the generic bindings.

For details on each properties, you can refer to ./pinctrl-bindings.txt.



Required sub-node properties:

  - pins

  - function



Optional sub-node properties:

  - bias-disable

  - bias-pull-up

  - bias-pull-down

  - output-high

  - output-low



Legacy pin configuration and multiplexing binding:

*** (Its use is deprecated, use generic multiplexing and configuration

bindings instead)



Required subnode-properties:

- 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.
