2015-12-29watchdog: Create watchdog device in watchdog_dev.cGuenter Roeck1-2/+2
The watchdog character device is currently created in watchdog_dev.c, and the watchdog device in watchdog_core.c. This results in cross-dependencies, since device creation needs to know the watchdog character device number as well as the watchdog class, both of which reside in watchdog_dev.c. Create the watchdog device in watchdog_dev.c to simplify the code. Inspired by earlier patch set from Damien Riegel.

2015-12-27watchdog: Use static struct class watchdog_class in stead of pointerPratyush Anand1-1/+1
We need few sysfs attributes to know different status of a watchdog device. To do that, we need to associate .dev_groups with watchdog_class. So convert it from pointer to static. Putting this static struct in watchdog_dev.c, so that static device attributes defined in that file can be attached to it.

2012-05-30watchdog: Add multiple device supportAlan Cox1-0/+4
We keep the old /dev/watchdog interface file for the first watchdog via miscdev. This is basically a cut and paste of the relevant interface code from the rtc driver layer tweaked for watchdog.
