- 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).
