Unsupported on Maxim MAX735x. Could this be modelled by a YAML schema instead ? Something like allOf: - if: properties: compatible: contains: enum: - maxim,max7356 - maxim,max7357 - maxim,max7358 then: properties: interrupts: false (untested, it would be nice to use a pattern check for the compatible property if possible) > > "#interrupt-cells": > const: 2 > @@ -100,6 +105,41 @@ examples: > #size-cells = <0>; > reg = <4>; > > + rtc@51 { > + compatible = "nxp,pcf8563"; > + reg = <0x51>; > + }; > + }; > + }; > + }; > + > + - | > + i2c { > + #address-cells = <1>; > + #size-cells = <0>; > + > + i2c-mux@74 { > + compatible = "maxim,max7357"; > + #address-cells = <1>; > + #size-cells = <0>; > + reg = <0x74>; > + > + i2c@1 { > + #address-cells = <1>; > + #size-cells = <0>; > + reg = <1>; > + > + eeprom@54 { > + compatible = "atmel,24c08"; > + reg = <0x54>; > + }; > + }; > + > + i2c@7 { > + #address-cells = <1>; > + #size-cells = <0>; > + reg = <7>; > + > rtc@51 { > compatible = "nxp,pcf8563"; > reg = <0x51>; -- Regards, Laurent Pinchart
