Subject: [PATCH 2/3] watchdog: sama5d4_wdt: add support for sama7g5-wdt
Date: Thu, 27 May 2021 13:01:19 +0300 [thread overview]
Message-ID: <20210527100120.266796-2-eugen.hristev@microchip.com> (raw)
In-Reply-To: <20210527100120.266796-1-eugen.hristev@microchip.com>
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).
