1* Nuvoton NPCM7xx KCS (Keyboard Controller Style) IPMI interface
2
3The Nuvoton SOCs (NPCM7xx) are commonly used as BMCs
4(Baseboard Management Controllers) and the KCS interface can be
5used to perform in-band IPMI communication with their host.
6
7Required properties:
8- compatible : should be one of
9 "nuvoton,npcm750-kcs-bmc"
10- interrupts : interrupt generated by the controller
11- kcs_chan : The KCS channel number in the controller
12
13Example:

16 compatible = "nuvoton,npcm750-lpc-kcs", "simple-mfd", "syscon";

18 reg-io-width = <1>;

20 #address-cells = <1>;
21 #size-cells = <1>;
22 ranges = <0x0 0xf0007000 0x40>;
