Merge tag 'for-linus-4.9-2' of git://git.code.sf.net/p/openipmi/linux-ipmi
Pull IPMI updates from Corey Minyard: "A small bug fix and a new driver for acting as an IPMI device. I was on vacation during the merge window (a long vacation) but this is a bug fix that should go in and a new driver that shouldn't hurt anything. This has been in linux-next for a month or so" * tag 'for-linus-4.9-2' of git://git.code.sf.net/p/openipmi/linux-ipmi: ipmi: fix crash on reading version from proc after unregisted bmc ipmi/bt-bmc: remove redundant return value check of platform_get_resource() ipmi/bt-bmc: add a dependency on ARCH_ASPEED ipmi: Fix ioremap error handling in bt-bmc ipmi: add an Aspeed BT IPMI BMC driver

+* Aspeed BT (Block Transfer) IPMI interface
+
+The Aspeed SOCs (AST2400 and AST2500) are commonly used as BMCs
+(BaseBoard Management Controllers) and the BT interface can be used to
+perform in-band IPMI communication with their host.
+
+Required properties:
+
+- compatible : should be "aspeed,ast2400-bt-bmc"
+- reg: physical address and size of the registers
+
+Optional properties:
+
+- interrupts: interrupt generated by the BT interface. without an
+ interrupt, the driver will operate in poll mode.
+
+Example:
+
+ ibt@1e789140 {
+ compatible = "aspeed,ast2400-bt-bmc";
+ reg = <0x1e789140 0x18>;
+ interrupts = <8>;
+ };
