-The Nuvoton SOCs (NPCM7xx) are commonly used as BMCs
+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
provides the access of KCS IO space for BMC side.
