* 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" - 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-ibt-bmc"; reg = <0x1e789140 0x18>; interrupts = <8>; };
