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.

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
