watchdog: Intel SCU Watchdog Timer Driver for Moorestown and Medfield platforms.
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.
