Hi Krzysztof, Thanks for your helpful comments! I have so some questions want to ask you below.

I will try to add some text in "description" and "io-channel-names", like below ---------------------------------- io-channels: description: | Use ADC channel to read VBUS, IBUS, IBAT, etc., info. Ibus ADC channel is required. It can be seen in include/dt-bindings/iio/adc/mediatek,mt6370_adc.h minItems: 1 maxItems: 9 io-channel-names: items: - const: vbusdiv5 - const: vbusdiv2 - ... ---------------------------------- Did these modifications meet your expectations? > > + minItems: 1 > > + maxItems: 9 > > + > > + usb-otg-vbus-regulator: > > + type: object > > + description: OTG boost regulator. > > + $ref: /schemas/regulator/regulator.yaml# > > unevaluatedProperties: false I will add this in the next patch. > > > + > > + properties: > > + enable-gpio: > > "gpios", so: > enable-gpios If this otg regulator only uses one GPIO Pin, do I still need to change to "gpios"?

The best would be something like this: Documentation/devicetree/bindings/power/supply/cpcap-charger.yaml so also "items" with description under "io-channels". You need to skip maxItems in such case (keep minItems). > - ... > ---------------------------------- > Did these modifications meet your expectations? > >>> + minItems: 1 >>> + maxItems: 9 >>> + >>> + usb-otg-vbus-regulator: >>> + type: object >>> + description: OTG boost regulator. >>> + $ref: /schemas/regulator/regulator.yaml# >> >> unevaluatedProperties: false > > I will add this in the next patch. > >> >>> + >>> + properties: >>> + enable-gpio: >> >> "gpios", so: >> enable-gpios > > If this otg regulator only uses one GPIO Pin, do I still need to > change to "gpios"? Yes, because "gpios" is the preferred suffix. This is requirement for all such properties. enable-gpios are also documented here: Documentation/devicetree/bindings/gpio/gpio-consumer-common.yaml > If so, I will refine it along with the regulator "enable-gpio" in MFD > dt-binding. Yes, there it should be "enable-gpios" as well. Best regards, Krzysztof
