* watchdog: wm831x: Convert to gpio_request_one()Mark Brown2012-05-231-10/+3
| | | | | | | Use the more modern API. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* watchdog: fix set_timeout operationsWim Van Sebroeck2012-03-271-0/+2
| | | | | | | | | Since we changed the behaviour of the set_timeout operation in the watchdog API, we need to change the allready converted drivers so that they update the timeout field at the end of the set_timeout operation. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* watchdog: nowayout is boolWim Van Sebroeck2012-03-271-2/+2
| | | | | | | nowayout is actually a boolean value. So make it bool for all watchdog device drivers. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* watchdog: Convert wm831x driver to devm_kzalloc()Mark Brown2012-01-061-4/+3
| | | | | | | Saves a small amount of code and systematically eliminates leaks. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* watchdog: add nowayout helpers to Watchdog Timer Driver Kernel APIWim Van Sebroeck2012-01-061-3/+1
| | | | | | | | | | Add two nowayout helpers for the Watchdog Timer Driver Kernel API. And apply this to the already converted drivers. Note: s3c2410_wdt lost the nowayout feature during the conversion.

* watchdog: Convert Wolfson drivers to module_platform_driverMark Brown2012-01-061-11/+1

* watchdog: Convert wm831x driver to watchdog coreMark Brown2011-11-051-213/+105
| | | | | | | | Fairly large code churn but not much doing with that and the overall result is a definite win. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* watchdog: Handle multiple wm831x watchdogs being registeredMark Brown2011-06-281-0/+5
| | | | | | | | | | | | Due to the whole single instance based watchdog API we use static data for the wm831x watchdog which means that if the system tries to register a second one we end up trying to register the same miscdevice again, corrupting the miscdevice list. Work around this by checking for duplicate registrations until we get a watchdog core. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* [WATCHDOG] watchdog_info constifyWim Van Sebroeck2010-03-071-1/+1

* [WATCHDOG] Add support for WM831x watchdogMark Brown2009-09-181-0/+441
The WM831x series of devices provide a watchdog with configurable behaviour on timer expiry. Currently this driver support refreshes via a register or GPIO line and autonomous refreshes from a hardware source (eg, a clock).
