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
