* watchdog: ebc-c384_wdt: Utilize devm_ functions in driver probe callbackWilliam Breathitt Gray2017-02-241-13/+1
| | | | | | | | | | | | The devm_ resource manager functions allow memory to be automatically released when a device is unbound. This patch takes advantage of the resource manager functions and replaces the watchdog_register_device call with the devm_watchdog_register_device call. In addition, the ebc_c384_wdt_remove function has been removed as no longer necessary due to the use of the relevant devm_ resource manager functions.

* watchdog: ebc-c384_wdt: Utilize the ISA bus driverWilliam Breathitt Gray2016-05-021-33/+10
| | | | | | | | | | | The WinSystems EBC-C384 watchdog timer is controlled via ISA bus communication. As such, the ISA bus driver is more appropriate than the platform driver for the WinSystems EBC-C384 watchdog timer driver.

* watchdog: Add watchdog timer support for the WinSystems EBC-C384William Breathitt Gray2016-03-011-0/+188
The WinSystems EBC-C384 has an onboard watchdog timer. The timeout range supported by the watchdog timer is 1 second to 255 minutes. Timeouts under 256 seconds have a 1 second granularity, while the rest have a 1 minute granularity. This driver adds watchdog timer support for this onboard watchdog timer. The timeout may be configured via the timeout module parameter.
