2018-03-24watchdog: Add Nuvoton NPCM watchdog driverJoel Stanley1-0/+254
The Nuvoton NPCM750 has a watchdog implemented as a single register inside the timer peripheral. This driver exposes that watchdog as a standard watchdog device with coarse timeout intervals, limited by the combination of prescaler and counter that is provided by the hardware. The calculation is taken from the Nuvoton vendor tree. The watchdog is left running if a bootloader had it going. The rate is the one specified in the device tree, or the default value (obtained from the datasheet). There is a pre-timeout IRQ that is wired up. This timeout always occurs 1024 clocks before the timeout.
