+Description: Selects the RX source of the UARTx device.
+
+ When read, each file shows the list of available options with currently
+ selected option marked by brackets "[]". The list of available options
+ depends on the selected file.
+
+ e.g.
+ cat /sys/bus/platform/drivers/aspeed-uart-routing/\*.uart_routing/uart1
+ [io1] io2 io3 io4 uart2 uart3 uart4 io6
+
+ In this case, UART1 gets its input from IO1 (physical serial port 1).
