-From e0769dda0adcabc41d322726b16148e3960473c1 Mon Sep 17 00:00:00 2001
-From: Oskar Senft <osk@google.com>
-Date: Wed, 8 Aug 2018 10:15:05 -0400
-Subject: [PATCH] misc: aspeed: Add Aspeed UART routing control driver.
-
-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.

-+Kernel driver aspeed-uart-routing
-+=================================
-+
-+Supported chips:
-+ASPEED AST2500/AST2600
-+
-+Author:
-+Google LLC
-+
-+Description
-+-----------
-+
-+The Aspeed AST2500/AST2600 allows to dynamically route the inputs for the
-+built-in UARTS and physical serial I/O ports.
-+
-+This allows, for example, to connect the output of UART to another UART.
-+This can be used to enable host<->BMC communication via UARTs, e.g. to allow
-+access to the host's serial console.
-+
-+This driver is for the BMC side. The sysfs files allow the BMC userspace
-+which owns the system configuration policy, to configure how UARTs and
-+physical serial I/O ports are routed.
-+
-+The driver provides the following files in sysfs:
-+uart1		Configure the input signal to UART1.
-+uart2		Configure the input signal to UART2.
-+uart3		Configure the input signal to UART3.
-+uart4		Configure the input signal to UART4.
-+uart5		Configure the input signal to UART5.
-+io1		Configure the input signal to physical serial port 1.
-+io2		Configure the input signal to physical serial port 2.
-+io3		Configure the input signal to physical serial port 3.
-+io4		Configure the input signal to physical serial port 4.
-+io5		Configure the input signal to physical serial port 5.
-+
-+When read, each file shows the list of available options with the currently
-+selected option marked by square brackets "[]". The list of available options
-+depends on the selected file.
-+
-+Example:
-+$ 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 signal from IO1 (physical serial port 1).
-+
-+$ echo -n "uart3" \
-+  >/sys/bus/platform/drivers/aspeed-uart-routing/*.uart_routing/uart1
-+$ cat /sys/bus/platform/drivers/aspeed-uart-routing/*.uart_routing/uart1
-+io1 io2 io3 io4 uart2 [uart3] uart4 io6
