Re: [PATCH v4 1/3] dt-bindings: pinctrl: bcm2835-gpio: Add generic pinctrl support

Hi Rob,

sorry I used allwinner,sunxi-pinctrl.txt from Maxime Ripard as a base, I used the same words, I thought it would be correct.

I will modify this to:

The BCM2835 pin configuration and multiplexing supports the generic bindings. For details on each properties, you can refer to
./pinctrl-bindings.txt.

If it's okay for you let me know, so I can send the v5 patch.

Best Regards
Matheus Castello
