2011-08-02watchdog: Cleanup WATCHDOG_CORE help textJosh Boyer
The newly added WATCHDOG_CORE option is a bool, but the help text suggests it can be built as a module. Fix it up. Signed-off-by: Josh Boyer <jwboyer@redhat.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
2011-07-28watchdog: WatchDog Timer Driver Core - Add basic frameworkWim Van Sebroeck
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.

2011-07-26watchdog: Add Xilinx watchdog timer driverAlejandro Cabrera
Watchdog timer device driver for Xilinx xps_timebase_wdt compatible ip cores. It takes watchdog timer configuration from device tree and it needs that its parent has defined the property "clock-frecuency". It is compatible with watchdog timer kernel API, so user apps like watchdogd may talk with it. Signed-off-by: Alejandro Cabrera <aldaya@gmail.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

Remove Kconfig regression caused by commit a4616153deae053b29a2b7dd9ec4b2a225accfc5 "watchdog: hpwdt: build hpwdt as module by default with NMI_DECODING enabled" 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 first write, and refresh on subsequent writes. 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.

2010-10-14powerpc/watchdog: Make default timeout for Book-E watchdog a Kconfig optionTimur Tabi
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.
