[PATCH 0/2] GPIO WDT "start-at-boot" property

[Francesco Zanella <francesco.zanella@vimar.com>]

I propose to add a new property to GPIO WDT device tree binding
"start-at-boot".
If this property is present, start pinging hw watchdog at probe, in order
to take advantage of kernel configs:
- WATCHDOG_HANDLE_BOOT_ENABLED: Avoid possible reboot if hw watchdog was
  been enabled before the kernel (by uboot for example) and userspace
  doesn't take control of /dev/watchdog in time;
- WATCHDOG_OPEN_TIMEOUT: Reboot if userspace doesn't take control of
  /dev/watchdog within the timeout.

  dt-bindings: watchdog: gpio-wdt: add "start-at-boot"
  watchdog: gpio_wdt: add "start-at-boot" feature
