Yes, look at this from
arch/arm64/boot/dts/arm/juno-motherboard.dtsi:
gpio_keys {
compatible = "gpio-keys";
#address-cells = <1>;
#size-cells = <0>;
button@1 {
debounce_interval = <50>;
wakeup-source;
linux,code = <116>;
label = "POWER";
gpios = <&iofpga_gpio0 0 0x4>;
};
button@2 {
debounce_interval = <50>;
wakeup-source;
linux,code = <102>;
label = "HOME";
gpios = <&iofpga_gpio0 1 0x4>;
};
(...)
Currently these names (POWER, HOME etc) appear nicely in
/proc/interrupts, so I guess the same should be used for input?
