+# Aspeed SSIF (SMBus system interface) IPMI BMC interface
+
+The Aspeed AST2500 are commonly used as BMCs (Baseboard Management Controllers)
+and the SSIF slave interface can be used to perform in-band IPMI communication
+with their host.
+
+Required properties:
+
+- compatible : should be
+       "aspeed,ast2500-ssif-bmc"
+- reg: I2C address the registers
+
+Example:
+
+       ssif-bmc@10 {
+               compatible = "aspeed,ast2500-ssif-bmc";
+               reg = <0x10>;
+       };
