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).
