3 Describes a simple watchdog timer which is reset by toggling a gpio.
7 - compatible: Must be "linux,wdt-gpio".
8 - gpios: From common gpio binding; gpio connection to WDT reset pin.
9 - hw_algo: The algorithm used by the driver. Should be one of the
11 - toggle: Toggle from high-to-low or low-to-high when resetting the watchdog.
12 - level: Maintain a constant high/low level, and trigger a short pulse when
13 resetting the watchdog. Active level is determined by the GPIO flags.
14 - always-running: Boolean property indicating that the watchdog cannot
15 be disabled. At present, U-Boot only supports this kind of GPIO
