+description: |
+  When the power-off handler is called, one more regulators are disabled
+  by calling regulator_force_disable(). If the power is still on and the
+  CPU still running after a 3000ms delay, a WARN_ON(1) is emitted.

+  compatible:
+    const: "regulator-poweroff"

+  regulator-names:
+    description:
+      Array of regulator names
+    $ref: /schemas/types.yaml#/definitions/string-array
+
+  REGULATOR-supply:
+    description:
+      For any REGULATOR listed in regulator-names, a phandle
+      to the corresponding regulator node
+    $ref: /schemas/types.yaml#/definitions/phandle
+
+  timeout-ms:
+    description:
+      Time to wait before asserting a WARN_ON(1). If nothing is
+      specified, 3000 ms is used.
