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 0fbcf4af7c83 ("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>;
+};
