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.
6
7Required properties:
8
9- compatible : should be one of
10 "aspeed,ast2400-ibt-bmc"
11 "aspeed,ast2500-ibt-bmc"
12 "aspeed,ast2600-ibt-bmc"
13- reg: physical address and size of the registers
14- clocks: clock for the device
15
16Optional properties:
17
18- interrupts: interrupt generated by the BT interface. without an
19 interrupt, the driver will operate in poll mode.

21Example:
22
23 ibt@1e789140 {
24 compatible = "aspeed,ast2400-ibt-bmc";
25 reg = <0x1e789140 0x18>;
26 interrupts = <8>;
27 clocks = <&syscon ASPEED_CLK_GATE_LCLK>;
28 };
