2020-10-06misc: aspeed: Add Aspeed UART routing control driver.Oskar Senft1-0/+383
This driver adds sysfs files that allow the BMC userspace to configure how UARTs and physical serial I/O ports are routed. Tested: Checked correct behavior (both read & write) on TYAN S7106 board by manually changing routing settings and confirming that bits flow as expected. Tested for UART1 and UART3 as this board doesn't have the other UARTs wired up in a testable way.
