Merge tag 'for-linus-4.3' of git://git.code.sf.net/p/openipmi/linux-ipmi

Pull IPMI updates from Corey Minyard:
 "Most of these have been sitting in linux-next for more than a release,
  particularly commit 0fbcf4af7c ("ipmi: Convert the IPMI SI ACPI
  handling to a platform device") which is probably the most complex
  patch.

  That is also the one that changes drivers/acpi/acpi_pnp.c.  The change
  in that file is only removing IPMI from a "special platform devices"
  list, since I convert it to the standard PNP interface.  I posted this
  one to the ACPI list twice and got no response, and it seems to work
  well in my testing, so I'm hoping it's good.

  Hidehiro Kawai posted a set of changes that improves the panic time
  handling in the IPMI driver.

  The rest of the changes are minor bug fixes or cleanups and some
  documentation"

IPMI device
Required properties:
- compatible: should be one of ipmi-kcs, ipmi-smic, or ipmi-bt
- device_type: should be ipmi
- reg: Address and length of the register set for the device
Optional properties:
- interrupts: The interrupt for the device. Without this the interface
is polled.
- reg-size - The size of the register. Defaults to 1
- reg-spacing - The number of bytes between register starts. Defaults to 1
- reg-shift - The amount to shift the registers to the right to get the data
into bit zero.
Example:
smic@fff3a000 {
compatible = "ipmi-smic";
device_type = "ipmi";
reg = <0xfff3a000 0x1000>;
interrupts = <0 24 4>;
reg-size = <4>;
reg-spacing = <4>;
};
