Hello Robert,
I am not an expert on this, but I have been modifying a watchdog driver lately. Please check my comments below, although they may need a review from the corresponding maintainer:
-----Original Message----- From: U-Boot u-boot-bounces@lists.denx.de On Behalf Of Robert Hancock Sent: Wednesday, June 19, 2019 12:53 AM To: u-boot@lists.denx.de Subject: [U-Boot] [PATCH] driver: watchdog: Add new iMX/LSCH2 WDT driver
This is a new watchdog timer driver for iMX and LSCH2 using the WDT framework and driver model. This allows ensuring that U-Boot uses the same watchdog timer instance and same settings (ex: internal or external reset) specified in the device tree.
This driver can be used in preference to the old imx_watchdog driver for boards which have been converted to use the driver model.

Why don't you overwrite drivers/watchdog/imx_watchdog.c?
Because there are still non-DM systems using it. However, I posted patches to add DM and DT probing support for imx_watchdog, so use that.
