+* 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";
+ };
