-Meson SoCs Watchdog timer
-
-Required properties:
-
-- compatible : depending on the SoC this should be one of:
-	"amlogic,meson6-wdt" on Meson6 SoCs
-	"amlogic,meson8-wdt" and "amlogic,meson6-wdt" on Meson8 SoCs
-	"amlogic,meson8b-wdt" on Meson8b SoCs
-	"amlogic,meson8m2-wdt" and "amlogic,meson8b-wdt" on Meson8m2 SoCs
-- reg : Specifies base physical address and size of the registers.
-
-Optional properties:
-- timeout-sec: contains the watchdog timeout in seconds.
-
-Example:
-
-wdt: watchdog@...09900 {
-	compatible = "amlogic,meson6-wdt";
-	reg = <0xc1109900 0x8>;
-	timeout-sec = <10>;
-};
