But no such luck: 1) There seems to be no binding for external leds in the input subsystem. 2) The keyboard is a usb one and get enumerated automatically, so not DT node by default. I guess I can remove it, but then I guess labels for the leds might be helpful when further customizing the DT locally, so why not just keep them? >> + gpios = <&pio 2 7 GPIO_ACTIVE_HIGH>; /* PC7 */ > > Ideally you should have LED labels here, following the scheme > devicename:colour:function Okay. >> + }; >> + >> + led_numlock: numlock { >> + gpios = <&pio 2 4 GPIO_ACTIVE_HIGH>; /* PC4 */ >> + }; >> + }; >> + >> + reg_usb1_vbus: usb1-vbus { >> + compatible = "regulator-fixed"; >> + regulator-name = "usb1-vbus"; >> + regulator-min-microvolt = <5000000>; >> + regulator-max-microvolt = <5000000>; >> + enable-active-high; >> + gpio = <&r_pio 0 7 GPIO_ACTIVE_HIGH>; /* PL7 */ >> + status = "okay"; > > I guess this one has a parent regulator too? Unless I failed to read the schematic correctly: No. The step-up converter providing 5V power for the usb1-vbus is connected directly to the IPS (intelligent power source) output of the PMIC and enabled directly by the 3.3V supply.

I'm not sure that would be useful either. I'd expect someone modifying the DT locally that they would modify the DT directly, and you already have the node there. > >> + reg_usb1_vbus: usb1-vbus { > >> + compatible = "regulator-fixed"; > >> + regulator-name = "usb1-vbus"; > >> + regulator-min-microvolt = <5000000>; > >> + regulator-max-microvolt = <5000000>; > >> + enable-active-high; > >> + gpio = <&r_pio 0 7 GPIO_ACTIVE_HIGH>; /* PL7 */ > >> + status = "okay"; > > > > I guess this one has a parent regulator too? > > Unless I failed to read the schematic correctly: No. > The step-up converter providing 5V power for the usb1-vbus is connected > directly to the IPS (intelligent power source) output of the PMIC and > enabled directly by the 3.3V supply.
