1* Aspeed BT (Block Transfer) IPMI interface2 3The Aspeed SOCs (AST2400 and AST2500) are commonly used as BMCs4(BaseBoard Management Controllers) and the BT interface can be used to5perform in-band IPMI communication with their host.6 7Required properties:8 9- compatible : should be one of10 "aspeed,ast2400-ibt-bmc"11 "aspeed,ast2500-ibt-bmc"12 "aspeed,ast2600-ibt-bmc"13- reg: physical address and size of the registers14- clocks: clock for the device15 16Optional properties:17 18- interrupts: interrupt generated by the BT interface. without an19 interrupt, the driver will operate in poll mode.20 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 };29
