Wim Van Sebroeck c9a0c8a684 [WATCHDOG] orion5x_wdt.c: 'ORION5X_TCLK' undeclared
orion5x_wdt no longer compiled after the changes in commit
ebe35aff88 ("Orion: prepare for
runtime-determined timer tick rate").

The tick rate define (ORION5X_TCLK) was removed in favor of a runtime
detection. The quick fix is to add the define in the watchdog driver.
The fix is not correct for all supported orion5x platforms, but since
the supported platforms right now are 133 Mhz and 166 Mhz, it won't
be _that_ far off. ;-) A fix that uses the runtime-determined timer
tick rate will be applied later.

fsl_get_sys_freq() may return -1 when 'soc' isn't found, but in
gef_wdt_probe() 'freq' is unsigned, so the test doesn't catch that.

Andrew Victor 2af29b7861 [ARM] 5390/1: AT91: Watchdog fixes
The recently merged AT91SAM9 watchdog driver uses the
AT91SAM9X_WATCHDOG config variable, whereas the original version of
the driver (and the platform support code) used AT91SAM9_WATCHDOG.
This causes the watchdog platform_device to never be registered, and
therefore the driver not to be initialized.

This patch:
- updates the platform support code to use AT91SAM9X_WATCHDOG.
- includes <linux/io.h> to fix compile error (same fix as was applied
to at91rm9200_wdt.c)
- fixes comment regarding watchdog clock-rates in at91rm9200.

GE Fanuc SBC610

Support for the FPGA based watchdog timer as found on GE Fanuc's SBC310,
SBC610 and PPC9A Single Board Computers.

This patch adds support for the watchdog timer found in one of the devices
FPGAs. There are two identical watchdog timers at different offsets in the
above mentioned boards, this driver is capable of supporting one of them.
The watchdog timers are also capable of generating interrupts at a
user-configurable threshold, though support for this operation is currently
not supported by the driver.

Linus Torvalds cd92a17eec iTCO_wdt: fix typo when setting TCO_EN bit
The code used '&= 0x00002000' when it tried to set the TCO_EN bit, which
obviously didn't set that bit at all, but instead just reset all the
other bits in the SMI_EN register.

This bug seemingly caused various random behavior, with Frans Pop
reporting that X.org just silently hung at startup and Rafael Wysocki
reports the fan spinning with full speed.

See
	http://lkml.org/lkml/2008/12/3/178
	http://bugzilla.kernel.org/show_bug.cgi?id=12162

The problem seems to have been triggered by "[WATCHDOG] iTCO_wdt :
problem with rebooting on new ICH9 based motherboards" (commit
7cd5b08be3), but the bogus code existed
before that too (in the "supermicro_old_pre_stop()" function), it just
apparently never showed up due to different logic.

In that commit the broken code got moved around and now gets executed
much more.

Bernhard Walle 290172e790 [WATCHDOG] hpwdt: Fix kdump when using hpwdt
When the "hpwdt" module is loaded (even if the /dev/watchdog device is not
opened), then kdump does not work. The panic kernel either does not start at
all or crash in various places.

The problem is that hpwdt_pretimeout is registered with register_die_notifier()
with the highest possible priority. Because it returns NOTIFY_STOP, the
crash_nmi_callback which is also registered with register_die_notifier()
is never executed. This causes the shutdown of other CPUs to fail.

Reverting the order is no option: The crash_nmi_callback executes HLT
and so never returns normally. Because of that, it must be executed as
last notifier, which currently is done.

So, that patch returns NOTIFY_OK to keep the crash_nmi_callback executed.

Arjan van de Ven af4c293ffc [WATCHDOG] pci: use pci_ioremap_bar() in drivers/watchdog
Use the newly introduced pci_ioremap_bar() function in drivers/watchdog.
pci_ioremap_bar() just takes a pci device and a bar number, with the goal
of making it really hard to get wrong, while also having a central place
to stick sanity checks.

Wim Van Sebroeck 7c2500f17d [WATCHDOG] ib700wdt.c - fix buffer_underflow bug
This fixes Bug 11399:
if ibwdt_set_heartbeat(int t) is called with value 30 then
the check "if ((t < 0) || (t > 30))" in ibwdt_set_heartbeat
is not going to fail because t == 30, but in the loop, the
check wd_times[i] > t is never going to be true because
none of the wd_times are greater than the value of t (i.e. 30).
So we are exiting the loop with i == -1 and therefore setting
wd_margin to -1 which is wrong.

Flemming Frandsen 7d8b090661 [WATCHDOG] Add driver for winbond w83697ug/uf watchdog feature
Adapted the w83627hf_wdt.c driver to work with the w83697ug/uf chip, 
found on MSI Fuzzy CX700 boards.

The method used is taken directly from the winbond datasheet and 
surprisingly it differs slightly from all the other winbond watchdogs.

So far it has only been tested on the CX700 board that I have, but it 
seems to work nicely.
