Wim Van Sebroeck 43316044d4 watchdog: WatchDog Timer Driver Core - Add basic framework
The WatchDog Timer Driver Core is a framework
that contains the common code for all watchdog-driver's.
It also introduces a watchdog device structure and the
operations that go with it.

This is the introduction of this framework. This part
supports the minimal watchdog userspace API (or with
other words: the functionality to use /dev/watchdog's
open, release and write functionality as defined in
the simplest watchdog API). Extra functionality will
follow in the next set of patches.

With the above change applied, hpwdt will be enabled unconditionally by just
entering the Watchdog subscreen in menuconfig. Since this driver is not
essential to boot any box it should remain disabled until it gets manually
enabled, just like all other drivers.

This submission includes:
  - Fix to intel_scu_write() to start watchdog timer the on the

    This enables Open, write, write, ... usage model.
  - Moves boot parameter checks from intel_scu_open() to
    intel_scu_watchdog_init(), so driver init will fail if these
    parameters are out of bounds.
  - Adds check for whether process waiting in wait_event_interruptible()
    received a signal while it was waiting.
  - Other small error handling changes.

Removed the read() method for now as that wass a non-standard behaviour.

Timur Tabi e0dc09ff9a powerpc/watchdog: Make default timeout for Book-E watchdog a Kconfig option
The PowerPC Book-E watchdog driver (booke_wdt.c) defines a default timeout
value in the code based on whether it's a Freescale Book-E part of not.
Instead of having hard-coded values in the driver, make it a Kconfig
option.

As newer chips gets faster, the current default values become less
appropriate, since the timeout sometimes occurs before the kernel finishes
booting.  Making the value a Kconfig option allows BSPs to configure a new
value without requiring the wdt_period command-line parameter to be set.

Paul Mundt b1fa888e01 watchdog: shwdt: Kill off mmap stub and superfluous comments.
The wdt mmaping thing was a special-cased hack that nothing in the wild
depends on, so just kill it off. While at it, sanitize the superfluous
comments in preparation for a driver rewrite and overhauled interface.

Geert Uytterhoeven aebaec975f [WATCHDOG] max63xx driver depends on ioremap()
Correct fix for the "ioremap() causes build failure on S390" should have been
a dependancy on HAS_IOMEM. So we add this dependancy also (and leave the driver
in the ARM section for now).
