The '$ref' has to be under an 'allOf' to work. It's an oddity of json-schema. However, anything with a standard unit suffix already has a schema to define the type, so you don't need to here and can just drop $ref. > + > + adi,tx-internal-delay-ps: > + $ref: /schemas/types.yaml#/definitions/uint32 > + description: | > + RGMII TX Clock Delay used only when PHY operates in RGMII mode with > + internal delay (phy-mode is 'rgmii-id' or 'rgmii-txid') in pico-seconds. > + enum: [ 1600, 1800, 2000, 2200, 2400 ] > + default: 2000 > + > + adi,fifo-depth-bits: > + $ref: /schemas/types.yaml#/definitions/uint32 > + description: | > + When operating in RMII mode, this option configures the FIFO depth. > + enum: [ 4, 8, 12, 16, 20, 24 ] > + default: 8 > + > + adi,disable-energy-detect: > + description: | > + Disables Energy Detect Powerdown Mode (default disabled, i.e energy detect > + is enabled if this property is unspecified) > + type: boolean > + > +examples: > + - | > + ethernet { > + #address-cells = <1>; > + #size-cells = <0>; > + > + phy-mode = "rgmii-id"; > + > + ethernet-phy@0 { > + reg = <0>; > + > + adi,rx-internal-delay-ps = <1800>; > + adi,tx-internal-delay-ps = <2200>; > + }; > + }; > + - | > + ethernet { > + #address-cells = <1>; > + #size-cells = <0>; > + > + phy-mode = "rmii"; > + > + ethernet-phy@1 { > + reg = <1>; > + > + adi,fifo-depth-bits = <16>; > + adi,disable-energy-detect; > + }; > + }; > diff --git a/MAINTAINERS b/MAINTAINERS > index e8aa8a667864..fd9ab61c2670 100644 > --- a/MAINTAINERS > +++ b/MAINTAINERS > @@ -944,6 +944,7 @@ L: netdev@xxxxxxxxxxxxxxx > W: http://ez.analog.com/community/linux-device-drivers > S: Supported > F: drivers/net/phy/adin.c > +F: Documentation/devicetree/bindings/net/adi,adin.yaml > > ANALOG DEVICES INC ADIS DRIVER LIBRARY > M: Alexandru Ardelean <alexandru.ardelean@xxxxxxxxxx> > -- > 2.20.1 >
