| 2 | |
| 3 | The Aspeed SOCs (AST2400 and AST2500) are commonly used as BMCs |
| 4 | (BaseBoard Management Controllers) and the BT interface can be used to |
| 5 | perform in-band IPMI communication with their host. |
| 6 | |
| 7 | Required 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 | |
| 16 | Optional properties: |
| 17 | |
| 18 | - interrupts: interrupt generated by the BT interface. without an |
| 19 | interrupt, the driver will operate in poll mode. |
| 20 | |
| 21 | Example: |
| 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 | }; |
