Hisilicon Hip06 Low Pin Count device Hisilicon Hip06 SoCs implement a Low Pin Count (LPC) controller, which provides I/O access to some legacy ISA devices. 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. Required properties: - compatible: value should be as follows: (a) "hisilicon,hip06-lpc" (b) "hisilicon,hip07-lpc" - #address-cells: must be 2 which stick to the ISA/EISA binding doc. - #size-cells: must be 1 which stick to the ISA/EISA binding doc. - reg: base memory range where the LPC register set is mapped. Note: The node name before '@' must be "isa" to represent the binding stick to the ISA/EISA binding specification. Example: isa@a01b0000 { compatible = "hisilicon,hip06-lpc"; #address-cells = <2>; #size-cells = <1>; reg = <0x0 0xa01b0000 0x0 0x1000>; ipmi0: bt@e4 { compatible = "ipmi-bt"; device_type = "ipmi"; reg = <0x01 0xe4 0x04>; }; };
