Kernel-4.18.0-80.el8_aspeed,ast2400-ibt-bmc

• 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>;
};
