* Nuvoton NPCM7xx KCS (Keyboard Controller Style) IPMI interface
|
|
|
|
The Nuvoton SOCs (NPCM7xx) are commonly used as BMCs
|
|
(Baseboard Management Controllers) and the KCS interface can be
|
|
used to perform in-band IPMI communication with their host.
|
|
|
|
Required properties:
|
|
- compatible : should be one of
|
|
"nuvoton,npcm750-kcs-bmc"
|
|
- interrupts : interrupt generated by the controller
|
|
- kcs_chan : The KCS channel number in the controller
|
|
|
|
Example:
|
|
|
|
lpc_kcs: lpc_kcs@f0007000 {
|
|
compatible = "nuvoton,npcm750-lpc-kcs", "simple-mfd", "syscon";
|
|
reg = <0xf0007000 0x40>;
|
|
reg-io-width = <1>;
|
|
|
|
#address-cells = <1>;
|
|
#size-cells = <1>;
|
|
ranges = <0x0 0xf0007000 0x40>;
|
|
|
|
kcs1: kcs1@0 {
|
|
compatible = "nuvoton,npcm750-kcs-bmc";
|
|
reg = <0x0 0x40>;
|
|
interrupts = <0 9 4>;
|
|
kcs_chan = <1>;
|
|
status = "disabled";
|
|
};
|
|
|
|
kcs2: kcs2@0 {
|
|
compatible = "nuvoton,npcm750-kcs-bmc";
|
|
reg = <0x0 0x40>;
|
|
interrupts = <0 9 4>;
|
|
kcs_chan = <2>;
|
|
status = "disabled";
|
|
};
|
|
};
