11*c6807970SChia-Wei Wang		e.g.
12*c6807970SChia-Wei Wang		cat /sys/bus/platform/drivers/aspeed-uart-routing/*.uart_routing/uart1
13*c6807970SChia-Wei Wang		[io1] io2 io3 io4 uart2 uart3 uart4 io6
14*c6807970SChia-Wei Wang
15*c6807970SChia-Wei Wang		In this case, UART1 gets its input from IO1 (physical serial port 1).
