[DRIVER][WDT] add SECO GPIO watchdog driver (!28) · Merge requests · edgehog / bsp / rockchip / linux-seco-rk

Yuri Mazzuoli requested to merge seco_5.10.110_develop_ym_wdt_gpio into seco_5.10.110 Oct 23, 2023

This is a generic driver for GPIO-based WDTs that use two GPIOs: enable and trigger. It is based on the linux GPIO-controlled watchdog driver.

There exists another SECO driver that can be used for similar hardware, having the compatible name "seco,apx-wdog": that one initializes the watchdog earlier in the boot process, and so is used if that more complex use case is necessary.
