1* Aspeed BT (Block Transfer) IPMI interface
2
3The Aspeed SOCs (AST2400 and AST2500) are commonly used as BMCs
4(BaseBoard Management Controllers) and the BT interface can be used to
5perform in-band IPMI communication with their host.

7Required properties:
8
9- compatible : should be one of
10	"aspeed,ast2400-ibt-bmc"
11	"aspeed,ast2500-ibt-bmc"
12- reg: physical address and size of the registers
13
14Optional properties:
15
16- interrupts: interrupt generated by the BT interface. without an
17  interrupt, the driver will operate in poll mode.

19Example:
20
21	ibt@1e789140 {
22		compatible = "aspeed,ast2400-ibt-bmc";
23		reg = <0x1e789140 0x18>;
24		interrupts = <8>;
25	};
