| 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). | |
