Moving the information out of the description down here seems like it would be better than what the original text binding does. Sorry for not point that out last time around. > + > + mediatek,apmixedsys: > + $ref: /schemas/types.yaml#/definitions/phandle > + description: > + A phandle to the APMIXEDSYS controller... Ideally the information about the purpose of the mux would go here, but I don't know the purpose of it :) > + "#thermal-sensor-cells": > + const: 1 > + > + bank0-supply: > + description: Regulator supplying voltage to the first bank Since I am an eejit, first bank of what? Sensors? Otherwise, LGTM. Cheers, Conor.
