Detailed Description

struct watchdog_device - The structure that defines a watchdog device

: The watchdog's ID. (Allocated by watchdog_register_device) : The watchdog's Character device. : The device for our watchdog : The parent bus device : Pointer to a watchdog_info structure. : Pointer to the list of watchdog operations. : Status of the watchdog device at boot. : The watchdog devices timeout value. :The watchdog devices minimum timeout value. :The watchdog devices maximum timeout value. -data:Pointer to the drivers private data. : Lock for watchdog core internal use only. : Field that contains the devices internal status bits.

The watchdog_device structure contains all information about a watchdog timer device.

The driver-data field may not be accessed directly. It must be accessed via the watchdog_set_drvdata and watchdog_get_drvdata helpers.

The lock field is for watchdog core internal use only and should not be touched.
