This looks pretty good, although I'd make a small addition.

See how below we have this pinmux definition already: fw_pinmux { wp { pins = "gpio53"; output-low; }; recovery { pins = "gpio57"; bias-none; }; developer { pins = "gpio41"; bias-none; }; }; So, you just need to add a phandle reference, and it'll look something like: keys { compatible = "gpio-keys"; pinctrl-0 = <&fw_pinmux>; pinctrl-names = "default"; ... }; ... fw_pinmux: fw_pinmux { recovery { ... }; }; You can see an approximately similar change I made recently here: https://git.openwrt.org/?p=openwrt/openwrt.git;a=commitdiff;h=4c1d7787d460cd0798eb01a42c6a8a7fc96e2999 If you have trouble with that, I can play with it myself and send an updated version 2.
