Patch 1 holds the driver and Patch 2 holds the Device Tree binding documentation. This driver was tested on the Keem Bay evaluation module board. Thank you, Vijay Changes since v1: - Fix indentation error in the dt-bindings file. - Use true/false in the second arg of keembay_wdt_set_timeout_reg(). - Fix the watchdog start sequence. - Avoid reduntant timeout register setting. - Remove min usage to find actual time at keembay_wdt_set_timeout(). - Remove timeout configuration boundary check at keembay_wdt_set_pretimeout(). - Use devm_watchdog_register_device() for wdt registration, which eventually supports driver unload functionality as well.
