 15 description:
 16   The Aspeed UART routing control allow to dynamically route the inputs for
 17   the built-in UARTS and physical serial I/O ports.
 18 
 19   This allows, for example, to connect the output of UART to another UART.
 20   This can be used to enable Host <-> BMC communication via UARTs, e.g. to
 21   allow access to the Host's serial console.
 22 
 23   This driver is for the BMC side. The sysfs files allow the BMC userspace
 24   which owns the system configuration policy, to configure how UARTs and
 25   physical serial I/O ports are routed.
