What: /sys/bus/platform/drivers/aspeed-uart-routing/\*/uart\* Date: September 2021 Contact: Oskar Senft Chia-Wei Wang 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).
