9 title: Aspeed UART Routing Controller
12 - Oskar Senft <osk@google.com>
13 - Chia-Wei Wang <chiawei_wang@aspeedtech.com>
16 The Aspeed UART routing control allow to dynamically route the inputs for
17 the built-in UARTS and physical serial I/O ports.
19 This allows, for example, to connect the output of UART to another UART.
