HiP06 is based on arm64 architecture where there is no I/O space. So, the I/O ports here are not CPU addresses, and there is no 'ranges' property in LPC device node. properties: $nodename: pattern: '^isa@[0-9a-f]+$' description: | The node name before '@' must be "isa" to represent the binding stick to the ISA/EISA binding specification. compatible: enum: - hisilicon,hip06-lpc - hisilicon,hip07-lpc reg: maxItems: 1 '#address-cells': const: 2 '#size-cells': const: 1 required: - compatible - reg additionalProperties: type: object examples: - | isa@a01b0000 { compatible = "hisilicon,hip06-lpc"; #address-cells = <2>; #size-cells = <1>; reg = <0xa01b0000 0x1000>; ipmi0: bt@e4 { compatible = "ipmi-bt"; device_type = "ipmi"; reg = <0x01 0xe4 0x04>; }; }; ...
