The "spba-bus" follows the "simple-bus" set of properties, as specified in the Devicetree Specification. It is an extension of "simple-bus" because the SDMA controller uses this compatible flag to determine which peripherals are available to it and the range over which the SDMA can access. There are no special clocks for the bus, because the SDMA controller itself has its interrupt and clock assignments. select: properties: compatible: contains: const: fsl,spba-bus required: - compatible properties: $nodename: pattern: "^spba-bus(@[0-9a-f]+)?$" compatible: items: - const: fsl,spba-bus - const: simple-bus '#address-cells': enum: [ 1, 2 ] '#size-cells': enum: [ 1, 2 ] reg: maxItems: 1 ranges: true required: - compatible - '#address-cells' - '#size-cells' - reg - ranges additionalProperties: type: object examples: - | spba-bus@30000000 { compatible = "fsl,spba-bus", "simple-bus"; #address-cells = <1>; #size-cells = <1>; reg = <0x30000000 0x100000>; ranges; };
