b4cc4aa24c [WATCHDOG] w83977f-watchdog-driver.patch
In a project for my company I've needed to use the watchdog device in a
PCM-5335 SBC from AAEON.  The watchdog timer is from a Winbond's SuperIO
chip, the W83977F.

I've made this driver based on two others already on the kernel tree,
the w83877f_wdt and the wdt977.

266aa1c4b3 [WATCHDOG] driver-for-ibm-automatic-server-restart-watchdog-fix2.patch
The device/watchdog has a fixed timeout/heartbeat.
So we don't support the WDIOC_SETTIMEOUT ioctl call
and we also may not set the WDIOF_SETTIMEOUT flag.

cc90ef0f9b [WATCHDOG] i6300esb.patch
I wrote earlier to the list[1] asking for a driver for the watchdog
included in the 6300ESB chipset.  I got a 2.4 driver via private email
from Ross Biro which I've changed into what I hope resembles a 2.6
driver (which was done by looking a lot at the watchdog drivers
already in the 2.6 tree).

I've attached the result, and I'm hoping to get some feedback on the
coding as a first step.  I can't actually test it on the hardware
right now as I won't have physical access until April. So my own tests
have been limited to "compiles-without-warnings" and
"can-be-insmodded-in-other-machine-without-oops".

a2f40ccd29 [PATCH] ppc32: Added support for the Book-E style Watchdog Timer
PowerPC 40x and Book-E processors support a watchdog timer at the processor
core level.  The timer has implementation dependent timeout frequencies
that can be configured by software.

One the first Watchdog timeout we get a critical exception.  It is left to
board specific code to determine what should happen at this point.  If
nothing is done and another timeout period expires the processor may
attempt to reset the machine.

Command line parameters:
  wdt=0 : disable watchdog (default)
  wdt=1 : enable watchdog

  wdt_period=N : N sets the value of the Watchdog Timer Period.

  The Watchdog Timer Period meaning is implementation specific. Check
  User Manual for the processor for more details.

This patch is based off of work done by Takeharu Kato.

1cc7724810 [WATCHDOG] softdog-timer-running-oops.patch
The softdog watchdog timer has a bug that can create an oops:

1.  Load the module without the nowayout option.
2.  Open the driver and close it without writing 'V' before close.
3.  Unload the module.  The timer will continue to run...
4.  Oops happens when timer fires.

Reported Sun, 10 Oct 2004, by Michael Schierl <schierlm@gmx.de>

Fix is easy: always take a reference on the module on open.
Release it only when the device is closed and no timer is running.
Tested on 2.6.13-rc6 using the soft_noboot option.  While the
timer is running and the device is closed, the module use count
stays at 1.  After the timer fires, it drops to 0.  Repeatedly
opening and closing the driver caused no problems.  Please apply.

Attached is a small update to the w83627hf watchdog driver
to initialise appropriately if it was already initialised
in the BIOS. On tyan motherboards for e.g. you can init
the watchdog to 4 mins, then when the driver is loaded it
sets the watchdog to "seconds" mode, and then machine will
reboot within 4 seconds. So this patch resets the timeout
to the configured value if the watchdog is already running.

2dab3cabc4 [WATCHDOG] correct sysfs name for watchdog devices
While looking for possible candidates for our udev.rules package,
I found a few odd ->name properties. /dev/watchdog has minor 130
according to devices.txt. Since all watchdog drivers use the
misc_register() call, they will end up in /sys/class/misc/$foo.
udev may create the /dev/watchdog node if the driver is loaded.
I dont have such a device, so I cant test it.
The drivers below provide names with spaces and even with / in it.
Not a big deal, but apps may expect /dev/watchdog.

9bbd037589 [PATCH] ARM: 2833/2: Remove support for WDIOF_MAGICCLOSE from sa1100-wdt
Patch from Ian Campbell

On PXA255 there is no way to disable the watchdog. Turning off OIER[E3]
as suggested in the existing comment does not work.

I posted a note to the ARM mailing list a little while ago asking for
opinions from people using SA1100. There was one reponse from Nico who
believes that the SA1100 is the same as the PXA255 in this respect.

You also asked me to involve the watchdog maintainer which I tried to
do but didn't hear anything back. There are only a couple of other
drivers which can't stop the watchdog and there seems to be no
consistancy regarding printing an error etc. I decided to print
something since that matches the case for all the other drivers when
NOWAYOUT is turned on.

Also, I changed the device .name to "watchdog" like most of the other
watchdogs. udev uses it as the device name (by default) and spaces etc.
get in the way.

Superceded 2833/1 because 2.6.13-rc4 caused rejects.

7586585897 [PATCH] PCI: clean up dynamic pci id logic
The dynamic pci id logic has been bothering me for a while, and now that
I started to look into how to move some of this to the driver core, I
thought it was time to clean it all up.

It ends up making the code smaller, and easier to follow, and fixes a
few bugs at the same time (dynamic ids were not being matched
everywhere, and so could be missed on some call paths for new devices,
semaphore not needed to be grabbed when adding a new id and calling the
driver core, etc.)

I also renamed the function pci_match_device() to pci_match_id() as
that's what it really does.

Add a watchdog using the RTAS OS surveillance service. This is
provided as a simpler alternative to rtasd. The added value
is that it works with standard watchdog client programs and
can therefore also do user space monitoring.

On BPA, rtasd is not really useful because the hardware does
not have much to report with event-scan.

The driver should also work on other platforms that support
the OS surveillance rtas calls.

e4fe19819e [PATCH] ARM: 2701/1: free up ixp2000 timer 4 for the watchdog
Patch from Lennert Buytenhek

The IXP2000 has four timers, but if we're on an A-step IXP2800, timer
2 and 3 don't work.  We need two timers for timekeeping (one for the
timer interrupt and one for tracking missed jiffies), so on early
IXP2800s we have no other choice but to use timer 1 and 4 for that,
but on all other IXP2000s we'd rather leave timer 4 free since that's
the only timer we can use for the watchdog.
So, on buggy IXP2000s (i.e. the A-step IXP2800) we use timer 4 for
tracking missed jiffies, and on all all non-buggy IXP2000s (i.e.
everything but the A-step IXP2800) we use timer 2.
On a pre-production IXP2800, this patch should print these messages
on boot:
	Enabling IXP2800 erratum #25 workaround
	Unable to use IXP2000 watchdog due to IXP2800 erratum #25
On any non-buggy IXP2800 (as well as on IXP2400s) you shouldn't see
anything at all, and the watchdog should be usable again.
