+UART routing control
+--------------------
+
+The UART routing control manages the RX muxes among the UART controllers
+and the I/O pins. This is typicall used for the Serial-Over-Lan (SOL)
+service.
+
+Required properties:
+
+ - compatible: One of:
+ "aspeed,ast2500-uart-routing";
+ "aspeed,ast2600-uart-routing";
+
+ - reg: offset and length of the IP in the LPC memory region
+
+Example:
+
+uart_routing: uart-routing@98 {
+ compatible = "aspeed,ast2600-uart-routing";
+ reg = <0x98 0x8>;
+};
