From ff83cc9f95aaba75991210312061b7fe52aaa400 Mon Sep 17 00:00:00 2001

Subject: [PATCH 189/247] watchdog: sama5d4_wdt: add support for sama7g5-wdt
Add support for compatible sama7g5-wdt.
The sama7g5 wdt is the same hardware block as on sam9x60.
Adapt the driver to use the sam9x60/sama7g5 variant if either
of the two compatibles are selected (sam9x60-wdt/sama7g5-wdt).
