Merge tag 'for-linus-4.17' of git://github.com/cminyard/linux-ipmi

Pull IPMI updates from Corey Minyard:
 "Mostly small changes, as usual.

  This does add an IPMI BMC server-side driver, to allow a Linux system
  to act as an IPMI controller. That's the biggest change, but it is
  just a new driver that is fairly narrow in use.

  The other largish change is removing ACPI SPMI probe support, which
  should have never really been there in the beginning"

* 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";
};
