* watchdog: max77620_wdt: constify platform_device_idArvind Yadav2017-09-091-1/+1
| | | | | | | | | | | | platform_device_id are not supposed to change at runtime. All functions working with platform_device_id provided by <linux/platform_device.h> work with const platform_device_id. So mark the non-const structs as const.

* watchdog: max77620_wdt: fix module autoloadJavier Martinez Canillas2016-12-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ $ modinfo drivers/watchdog/max77620_wdt.ko | grep alias $ After this patch: modinfo drivers/watchdog/max77620_wdt.ko | grep alias alias: platform:max77620-watchdog Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
* watchdog: max77620: Add support for watchdog timerLaxman Dewangan2016-07-171-0/+227
Maxim PMIC MAX77620 is Power management IC which have multiple sub blocks like regulators (DCDC/LDOs), GPIO, RTC, Clock, Watchdog timer etc. Add the driver for watchdog timer under watchdog framework. The driver implements the watchdog callbacks to start, stop, ping and set timeout for watchodg framework.
