1 # Aspeed KCS (Keyboard Controller Style) IPMI interface
3 The Aspeed SOCs (AST2400 and AST2500) are commonly used as BMCs
4 (Baseboard Management Controllers) and the KCS interface can be
5 used to perform in-band IPMI communication with their host.
9 - compatible : should be one of

11 "aspeed,ast2500-kcs-bmc"
12 - interrupts : interrupt generated by the controller
13 - kcs_chan : The LPC channel number in the controller
14 - kcs_addr : The host CPU IO map address
