It's probably unimportant, given you say this is unlikely to be used in new hardware, but it does seem odd to me to have two compatibles for the same chip. > >> + regulators: > >> + type: object > >> + additionalProperties: false > >> + > >> + properties: > >> + CHARGER: > >> + type: object > >> + $ref: /schemas/regulator/regulator.yaml# > >> + unevaluatedProperties: false > >> + description: > >> + CHARGER is main battery charger current control, wrongly represented > >> + as regulator. > >> + > >> + properties: > >> + regulator-min-microamp: > >> + minimum: 90000 > >> + maximum: 800000 > >> + > >> + regulator-max-microamp: > >> + minimum: 90000 > >> + maximum: 800000 > > > > Did you pull these from the datasheet, or from the dts/example? > > From the driver. Ah, thanks. Was just curious really. Other than the deprecated thing looking odd, this stuff seemed fine to me.
