1 * Nuvoton NPCM KCS (Keyboard Controller Style) IPMI interface
2
3 The Nuvoton SOCs (NPCM) are commonly used as BMCs
4 (Baseboard Management Controllers) and the KCS interface can be
5 used to perform in-band IPMI communication with their host.
6
7 Required properties:
8 - compatible : should be one of
9 "nuvoton,npcm750-kcs-bmc"
10 "nuvoton,npcm845-kcs-bmc", "nuvoton,npcm750-kcs-bmc"
11 - interrupts : interrupt generated by the controller
12 - kcs_chan : The KCS channel number in the controller
13
14 Example:
15
16 lpc_kcs: lpc_kcs@f0007000 {
17 compatible = "nuvoton,npcm750-lpc-kcs", "simple-mfd", "syscon";
18 reg = <0xf0007000 0x40>;
19 reg-io-width = <1>;
20
21 #address-cells = <1>;
22 #size-cells = <1>;
23 ranges = <0x0 0xf0007000 0x40>;
24
25 kcs1: kcs1@0 {
26 compatible = "nuvoton,npcm750-kcs-bmc";
27 reg = <0x0 0x40>;
28 interrupts = <0 9 4>;
29 kcs_chan = <1>;
30 status = "disabled";
31 };
32
