From ff83cc9f95aaba75991210312061b7fe52aaa400 Mon Sep 17 00:00:00 2001 From: Eugen Hristev Date: Thu, 27 May 2021 13:01:19 +0300 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).
