The device is always connected to the expansion bus of the IXP4xx SoCs using one or two chip select areas and address translating logic on the board. The node must be placed inside a chip select node on the IXP4xx expansion bus. properties: compatible: const: intel,ixp4xx-compact-flash reg: items: - description: Command interface registers - description: Control interface registers interrupts: maxItems: 1 required: - compatible - reg - interrupts allOf: - $ref: pata-common.yaml# - $ref: /schemas/memory-controllers/intel,ixp4xx-expansion-peripheral-props.yaml# unevaluatedProperties: false examples: - | #include bus@c4000000 { compatible = "intel,ixp43x-expansion-bus-controller", "syscon"; reg = <0xc4000000 0x1000>; native-endian; #address-cells = <2>; #size-cells = <1>; ranges = <0 0x0 0x50000000 0x01000000>, <1 0x0 0x51000000 0x01000000>; dma-ranges = <0 0x0 0x50000000 0x01000000>, <1 0x0 0x51000000 0x01000000>; ide@1,0 { compatible = "intel,ixp4xx-compact-flash"; reg = <1 0x00000000 0x1000>, <1 0x00040000 0x1000>; interrupt-parent = <&gpio0>; interrupts = <12 IRQ_TYPE_EDGE_RISING>; }; }; ...
