-* 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 one of
- "aspeed,ast2400-ibt-bmc"
- "aspeed,ast2500-ibt-bmc"
- "aspeed,ast2600-ibt-bmc"
-- reg: physical address and size of the registers
-- clocks: clock for the device
-
-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-ibt-bmc";
- reg = <0x1e789140 0x18>;
- interrupts = <8>;
- clocks = <&syscon ASPEED_CLK_GATE_LCLK>;
- };
