+* Nuvoton NPCM KCS (Keyboard Controller Style) IPMI interface
+
+The Nuvoton SOCs (NPCM) 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"
+    "nuvoton,npcm845-kcs-bmc", "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";
+        };
+    };
