-# Aspeed KCS (Keyboard Controller Style) IPMI interface
-
-The Aspeed SOCs (AST2400 and AST2500) are commonly used as BMCs
-(Baseboard Management Controllers) and the KCS interface can be
-used to perform in-band IPMI communication with their host.
-
-## v1
-Required properties:
-- compatible : should be one of
- "aspeed,ast2400-kcs-bmc"
- "aspeed,ast2500-kcs-bmc"
-- interrupts : interrupt generated by the controller
-- clocks : contains a phandle to the syscon node describing the clocks.
- There should then be one cell representing the clock to use.
-- kcs_chan : The LPC channel number in the controller
-- kcs_addr : The host CPU IO map address
-
-## v2
-Required properties:
-- compatible : should be one of
- "aspeed,ast2400-kcs-bmc-v2"
- "aspeed,ast2500-kcs-bmc-v2"
-- reg : The address and size of the IDR, ODR and STR registers
-- interrupts : interrupt generated by the controller
-- aspeed,lpc-io-reg : The host CPU LPC IO address for the device
-- clocks : contains a phandle to the syscon node describing the clocks.
- There should then be one cell representing the clock to use.
-
-Example:
-
- kcs3: kcs@24 {
- compatible = "aspeed,ast2500-kcs-bmc-v2";
- reg = <0x24 0x1>, <0x30 0x1>, <0x3c 0x1>;
- aspeed,lpc-reg = <0xca2>;
- interrupts = <8>;
- clocks = <&syscon ASPEED_CLK_GATE_LCLK>;
- status = "okay";
- };
