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"? If so, I will refine it along with the regulator "enable-gpio" in MFD dt-binding. > > > + maxItems: 1 > > + > > +required: > > + - compatible > > + - interrupts > > + - interrupt-names > > + - io-channels > > + > > +additionalProperties: false > > + > > +... > > > Best regards, > Krzysztof Best regards, ChiaEn Wu
