Nicolas Pitre 3b937a7dbd [ARM] Orion/Kirkwood: rename orion5x_wdt to orion_wdt
The Orion watchdog driver is also used on Kirkwood.

Convention is to use orion5x for stuff specific to 88F5xxx Orion chips
and simply "orion" for shared stuff across SoCs including Kirkwood.

Thomas Reitmayr 6462c6160a [ARM] orion5x: Change names of defines for Reset-Out-Mask register
The name of the define for the Reset-Out-Mask register as well as its
bit for the watchdog reset are changed to match the names used for
Kirkwood (which in turn match the processor specification more
closely). There is no functional change.

This patch prepares for adding orion5x_wdt as a platform device to
Kirkwood.

Nicolas Pitre fdd8b079e3 [ARM] 5460/1: Orion: reduce namespace pollution
Symbols like SOFT_RESET are way too generic to be exported at large.
To avoid this, let's move the mbus bridge register defines into a
separate file and include it where needed.  This affects mach-kirkwood,
mach-loki, mach-mv78xx0 and mach-orion5x simultaneously as they all
share code in plat-orion which relies on those defines.

Some other defines have been moved to narrower scopes, or simply deleted
when they had no user.

This fixes compilation problem with mpt2sas on the above listed
platforms.

Uwe Kleine-König 0e3912c75f [WATCHDOG] omap_wdt.c: move probe function to .devinit.text
A pointer to omap_wdt_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

just make it static because this can be compiled in as a module.

Julia Lawall 2855d28a35 [PATCH 13/13] drivers/watchdog: use USB API functions rather than constants
This set of patches introduces calls to the following set of functions:

usb_endpoint_dir_in(epd)
usb_endpoint_dir_out(epd)
usb_endpoint_is_bulk_in(epd)
usb_endpoint_is_bulk_out(epd)
usb_endpoint_is_int_in(epd)
usb_endpoint_is_int_out(epd)
usb_endpoint_num(epd)
usb_endpoint_type(epd)
usb_endpoint_xfer_bulk(epd)
usb_endpoint_xfer_control(epd)
usb_endpoint_xfer_int(epd)
usb_endpoint_xfer_isoc(epd)

In some cases, introducing one of these functions is not possible, and it
just replaces an explicit integer value by one of the following constants:

USB_ENDPOINT_XFER_BULK
USB_ENDPOINT_XFER_CONTROL
USB_ENDPOINT_XFER_INT
USB_ENDPOINT_XFER_ISOC

An extract of the semantic patch that makes these changes is as follows:

The WDT timer ticks quite fast (half of the CPU clock speed, which may

size of 32Bit, the maximum timeout value ranges from about 21s to 43s,
depending on the configured CPU clock speed.

This patch add's the timeout module parameter and checks that it's not
bigger then the maximum timeout for the given clock speed.

Ming Lei 7a192ec334 platform driver: fix incorrect use of 'platform_bus_type' with 'struct device_driver'
This patch fixes the bug reported in
	http://bugzilla.kernel.org/show_bug.cgi?id=11681.

"Lots of device drivers register a 'struct device_driver' with
the '.bus' member set to '&platform_bus_type'. This is wrong,
since the platform_bus functions expect the 'struct device_driver'
to be wrapped up in a 'struct platform_driver' which provides
some additional callbacks (like suspend_late, resume_early).
The effect may be that platform_suspend_late() uses bogus data
outside the device_driver struct as a pointer pointer to the
device driver's suspend_late() function or other hard to
reproduce failures."(Lothar Wassmann)

Eric Miao 5bf3df3f00 [ARM] pxa: separate definitions from pxa-regs.h and remove it finally
The remaining registers are separated into:

   - <mach/regs-ost.h>
   - <mach/regs-rtc.h>
   - <mach/regs-intc.h>

and then we can remove pxa-regs.h completely. Instead of #include this
file, let's:

1. include the specific <mach/regs-*.h> with care (if that's absolutely
   necessary)

2. define the registers in the driver, make cleanly defined API to expose
   the register access to external with sufficient reason

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.

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.

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.

Wim Van Sebroeck c6904ddb97 [WATCHDOG] iTCO_wdt : correct status clearing
The iTCO_wdt code was not clearing the correct bits.
It now clears the timeout status bit and then the
SECOND_TO_STS bit and then the BOOT_STS bit.
Note: we should first clear the SECOND_TO_STS bit
before clearing the BOOT_STS bit.

Wim Van Sebroeck 7cd5b08be3 [WATCHDOG] iTCO_wdt : problem with rebooting on new ICH9 based motherboards
Bugzilla #9868: On Intel motherboards with the ICH9 based I/O controllers
(Like DP35DP and DG33FB) the iTCO timer counts but it doesn't reboot the
system after the counter expires.

This patch fixes this by moving the enabling & disabling of the TCO_EN bit
in the SMI_EN register into the start and stop code.

Matthias Fuchs 0a0e9e0cb9 powerpc: Fix Book-E watchdog timer interval setting
This patch fixes the setting of the Book-E watchdog timer interval setup
on initialization and by ioctl().

On initialization the period bits have to be masked before setting
a new period.

In WDIOC_SETTIMEOUT ioctl we have to use the correct mask.

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.
