   4 Subject: [PATCH 189/247] watchdog: sama5d4_wdt: add support for sama7g5-wdt
   5
   6 Add support for compatible sama7g5-wdt.
   7 The sama7g5 wdt is the same hardware block as on sam9x60.
   8 Adapt the driver to use the sam9x60/sama7g5 variant if either
   9 of the two compatibles are selected (sam9x60-wdt/sama7g5-wdt).
