2019-05-05watchdog: da9062_wdt: Use 'dev' instead of dereferencing it repeatedlyGuenter Roeck1-12/+8
Introduce local variable 'struct device *dev' and use it instead of dereferencing it repeatedly. Also replace 'ret = func(); return ret;' with 'return func();'. The conversion was done automatically with coccinelle using the following semantic patches.

The patch "watchdog: da9062: use protection delay mechanism from core" (fb484262) removed the only user of j_time_stamp. This turned into some leftover functions that are removed with this patch.

2017-12-28watchdog: da9062: Disable and wait before changing timeoutMichael Grzeschik1-0/+7
The DA9062 watchdog occasionally enters error condition and resets the system if the timeout is changed quickly after the timer was enabled. The method of disabling and waiting for > 150 µs before setting the new timeout is taken from the DA9052 driver.

2017-12-28watchdog: da9062: Add restart handler supportMichael Grzeschik1-0/+22
Register a restart handler for the da9062 watchdog. System restart is triggered by sending the shutdown command to the PMIC. As more-suitable restart handlers may exist, the priority of the watchdog restart handler is set to 128.

2016-12-16watchdog: da9062/61: watchdog driverSteve Twiss1-2/+10
The of_device_id match array is added to support "dlg,da9062-watchdog" as a valid .compatible string. A MODULE_DEVICE_TABLE() macro is added. This patch assumes the use of a DA9062 fallback compatible string for the DTS to pick up the DA9062 device driver for use with the DA9061 watchdog hardware Copyright header is updated to add DA9061 in its description and the module description macro is extended to include DA9061. Kconfig is updated to reflect support for DA9061/62.

2015-09-09Watchdog: Fix parent of watchdog_devicesPratyush Anand1-0/+1
/sys/class/watchdog/watchdogn/device/modalias can help to identify the driver/module for a given watchdog node. However, many wdt devices do not set their parent and so, we do not see an entry for device in sysfs for such devices. This patch fixes parent of watchdog_device so that /sys/class/watchdog/watchdogn/device is populated. Exceptions: booke, diag288, octeon, softdog and w83627hf -- They do not have any parent. Not sure, how we can identify driver for these devices.
