-* 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";
