-* Dialog Semiconductor DA9062/61 Watchdog Timer
-
-Required properties:
-
-- compatible: should be one of the following valid compatible string lines:
-	"dlg,da9061-watchdog", "dlg,da9062-watchdog"
-	"dlg,da9062-watchdog"
-
-Optional properties:
-- dlg,use-sw-pm: Add this property to disable the watchdog during suspend.
-	Only use this option if you can't use the watchdog automatic suspend
-	function during a suspend (see register CONTROL_B).
-- dlg,wdt-sd: Set what happens on watchdog timeout. If this bit is set the
-	watchdog timeout triggers SHUTDOWN, if cleared the watchdog triggers
-	POWERDOWN. Can be 0 or 1. Only use this option if you want to change the
-	default chip's OTP setting for WATCHDOG_SD bit. If this property is NOT
-	set the WATCHDOG_SD bit and on timeout watchdog behavior will match the
-	chip's OTP settings.
-
-Example: DA9062
-
-	pmic0: da9062@58 {
-		watchdog {
-			compatible = "dlg,da9062-watchdog";
-		};
-	};
-
-Example: DA9061 using a fall-back compatible for the DA9062 watchdog driver
-
-	pmic0: da9061@58 {
-		watchdog {
-			compatible = "dlg,da9061-watchdog", "dlg,da9062-watchdog";
-		};
-	};
