* watchdog: add watchdog pollerOleksij Rempel2018-03-261-0/+4
| | | | | | | | | | In some cases it is practical to supervise as much as possible of the barebox execution with a watchdog (or multiple watchdogs). This patch provides an async poller for watchdog core framework which can be enabled by the user and stores this configuration to nv.

* watchdog: provide timeout_cur valueOleksij Rempel2018-03-231-0/+1
| | | | | | | | | | timeout_cur will be used for watchdog poller. Provided values should be good enough for most users and still can be changed for separate projects and fit to needed requirements.

* watchdog: move max timeout test in to wd_coreOleksij Rempel2018-03-231-0/+1
| | | | | | | this also will be needed for watchdog poller as well Signed-off-by: Oleksij Rempel <linux@rempel-privat.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* watchdog: register watchdog virtual device with short name wdogOleksij Rempel2018-03-231-0/+1
| | | | | | | | | | | | the watchdog hwdev is usually named with devicetree schema which is not practical for CLI. On device registration "wdog" will be extended with some index number extracted from devicetree (if awailable) or automatically assigned first available number. End result will be "wdog0" .. etc. Signed-off-by: Oleksij Rempel <o.rempel@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * watchdog: Allow multiple watchdogsSascha Hauer2015-08-271-0/+6
| | | | | | | | | | | | | | | | | | Put watchdogs on a list to allow multiple watchdogs. Add a priority field to be able to pick the highest priority watchdog. This patch also provides a of_get_watchdog_priority() function to allow configuring the watchdog priority from the device tree. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
