+title: Force-disable power regulator to turn the power off.
+
+maintainers:
+  - Michael Klein <michael@...sekall.de>
+
+description: |
+  When the power-off handler is called, a power regulator is disabled by
+  calling regulator_force_disable(). If the power is still on and the
+  CPU still running after a 3000ms delay, a warning is emitted.
+
+properties:
+  compatible:
+    const: "regulator-poweroff"
+
+  power-supply:
+    description:
+      regulator to disable on power-down
+
+required:
+  - compatible
+  - power-supply
+
+additionalProperties: false
+
+examples:
+  - |
+    regulator-poweroff {
+        compatible = "regulator-poweroff";
+        power-supply = <&reg_vcc1v2>;
