With the early_enable module parameter the watchdog can be started during driver probe time. If this is requested the bets are good that the timer is already running, so to narrow the gap where the timer is disabled only call the disable function when the timer shouldn't be started. Signed-off-by:

omap_wdt_start calls pm_runtime_get_sync so dropping a reference just before calling omap_wdt_start doesn't make much sense. Moreover there is no point to use the synchronous variant of pm_runtime_put because the driver doesn't care if the clock is disabled before or after omap_wdt_probe returns. Signed-off-by:

On 64bit platforms, "(1 << (16 + top)) / clk_get_rate(dw_wdt.clk)" is sign-extended to 64bit then converted to unsigned 64bit, finally divide the clk rate. If the top is the maximum TOP i.e 15, "(1 << (16 +15))" will be sign-extended to 0xffffffff80000000, then converted to unsigned 0xffffffff80000000, which is a huge number, thus the final result is wrong. We fix this issue by giving usigned value(1U in this case) at first. Let's assume clk rate is 25MHZ, Before the patch: dw_wdt_top_in_seconds(15) = -864612050 After the patch: dw_wdt_top_in_seconds(15) = 85 Signed-off-by:

This allows the system to actually halt even if userspace forgot to disable the watchdog first. Old behaviour was that the watchdog forced the system to boot again. Signed-off-by:

This patch adds following attributes to watchdog device's sysfs interface to read its different status. * state - reads whether device is active or not * identity - reads Watchdog device's identity string. * timeout - reads current timeout. * timeleft - reads timeleft before watchdog generates a reset * bootstatus - reads status of the watchdog device at boot * status - reads watchdog device's internal status bits * nowayout - reads whether nowayout feature was set or not Testing with iTCO_wdt: # cd /sys/class/watchdog/watchdog1/ # ls bootstatus dev device identity nowayout power state subsystem timeleft timeout uevent # cat identity iTCO_wdt # cat timeout 30 # cat state inactive # echo > /dev/watchdog1 # cat timeleft 26 # cat state active # cat bootstatus 0 # cat nowayout 0 Signed-off-by:

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. Signed-off-by:

Get rid of the custom reboot notifier block registration and use the one provided by the watchdog core. Note that this watchdog used to stop unconditionnaly on SYS_HALT and SYS_POWER_OFF. The core function now calls ops->stop on SYS_HALT and SYS_DOWN. To prevent the watchdog from being stopped on reboot, the "always-running" property must be set, otherwise it will now be stopped.

Damien Riegel authored
Many watchdog drivers register a reboot notifier in order to stop the watchdog on system reboot. Thus we can factorize this code in the watchdog core. For that purpose, a new notifier block is added in watchdog_device for internal use only, as well as a new watchdog_stop_on_reboot helper function. If this helper is called, watchdog core registers the related notifier block and will stop the watchdog when SYS_HALT or SYS_DOWN is received. Since this operation can be critical on some platforms, abort the device registration if the reboot notifier registration fails. Suggested-by:

Damien Riegel authored
Many watchdog drivers implement the same code to register a restart handler. This patch provides a generic way to set such a function. The patch adds a new restart watchdog operation. If a restart priority greater than 0 is needed, the driver can call watchdog_set_restart_priority to set it. Suggested-by:
