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>;
};

};
