From c5f4644e6c8ba21666128603e4e92544d3cd740d Mon Sep 17 00:00:00 2001
From: Russell King <rmk@dyn-67.arm.linux.org.uk>
Date: Wed, 29 Jun 2005 09:42:38 +0100
Subject: [PATCH 1/4] [PATCH] Serial: Adjust serial locking

This patch changes the way serial ports are locked when getting modem
status.  This change is necessary because we will need to atomically
read the modem status and take action depending on the CTS status.

Subject: [PATCH 2/4] [PATCH] Serial: Check status of CTS when using flow
 control

Fix bugme #4712: read the CTS status and set hw_stopped if CTS
is not active when opening the port and/or enabling CRTSCTS

Thanks to Stefan Wolff for spotting this problem.

Subject: [PATCH 3/4] [PATCH] Serial: Disable OX950 transmitter for flow
 control

Disable the transmitter whenever we want to prevent characters
being transmitted by flow control.  However, if we run out of
characters to send and want to only disable the TX interrupt,
allow that scenario.

Subject: [PATCH 4/4] [PATCH] Serial: Split 8250 port table (part 2)

Remove legacy ISA serial ports for Accent, Boca, Fourport, Hub6 and MCA
from the architecture specific serial.h include.

The only ports which remain in asm-*/serial.h are the platform specific
entries.  These should really be converted by platform maintainers to
use a platform device, such as can be found in
arch/arm/mach-footbridge/isa.c
