- Add compilation flag to treat warning as error - Handle error of unused variable - Handle error of uninitialised variable bug 949219 Change-Id: I07437be5eaa7bf7abe5494c828690b6be3b98178 Signed-off-by: schowdary <schowdary@nvidia.com> Reviewed-on: http://git-master/r/118039 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Sachin Nikam <snikam@nvidia.com>

These changes have no effect if CONFIG_GCOV_KERNEL is not set in defconfig. It is easier to trigger GCOV for kernel if this patch is in by only setting the before mentioned flag.

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>

2011-03-15watchdog: Intel SCU Watchdog Timer Driver for Moorestown and Medfield platforms.Donald Johnson
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. Removed the read() method for now as that wass a non-standard behaviour.
