+======================================================================
+Device tree bindings for Aspeed AST2400/AST2500 UART Routing Control Driver
+======================================================================
+
+The Aspeed AST2500 allows to dynamically route the inputs for the built-in
+UARTS and physical serial I/O ports.
+
+Required properties:
+===================
+
+ - compatible: must be one of:
+ - "aspeed,ast2400-uart-routing"
+ - "aspeed,ast2500-uart-routing"
+
+Optional properties:
+===================
+
+The uart-routing node should be the child of a lpc node with the required
+property:
+
+- compatible : Should be one of the following:
+ "aspeed,ast2400-lpc", "simple-mfd"
+ "aspeed,ast2500-lpc", "simple-mfd"
+
+Example
+===================
+
+g5 Example
+----------
+
+lpc: lpc at 1e789000 {
+ compatible = "aspeed,ast2500-lpc", "simple-mfd";
+ reg = <0x1e789000 0x1000>;
+
+ uart_routing: uart_routing at 9c {
+ compatible = "aspeed,ast2500-uart-routing";
+ reg = <0x9c 0x4>;
+ };
+};
