The KCS (Keyboard Controller Style) interface is used to perform in-band IPMI communication between a server host and its BMC (BaseBoard Management Controllers). This driver exposes the KCS interface on ASpeed SOCs (AST2400 and AST2500) as a character device. Such SOCs are commonly used as BMCs and this driver implements the BMC side of the KCS interface.

* 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.
|
|
|
|
Required properties:
|
|
- compatible : should be one of
|
|
"aspeed,ast2400-kcs-bmc"
|
|
"aspeed,ast2500-kcs-bmc"
|
|
- interrupts : interrupt generated by the controller
|
|
- kcs_chan : The LPC channel number in the controller
|
|
- kcs_addr : The host CPU IO map address
|
|
|
|
|
|
Example:
|
|
|
|
kcs3: kcs3@0 {
|
|
compatible = "aspeed,ast2500-kcs-bmc";
|
|
reg = <0x0 0x80>;
|
|
interrupts = <8>;
|
|
kcs_chan = <3>;
|
|
kcs_addr = <0xCA2>;
|
|
status = "okay";
|
|
};
