[PATCH v9 2/9] watchdog: rzg2l_wdt: Make the driver depend on PM

From: Claudiu
Date: Fri May 31 2024 - 02:58:29 EST


From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>

The rzg2l_wdt watchdog driver cannot work w/o CONFIG_PM=y (e.g. the
clocks are enabled though pm_runtime_* specific APIs). To avoid building
a driver that doesn't work make explicit the dependency on CONFIG_PM.
