+Regulator consumer for rfkill devices
+
+Required properties:
+- compatible : Must be "rfkill-regulator".
+- label : Name of rfkill device.
+- type : Type of rfkill device.
+
+Possible values (defined in include/dt-bindings/net/rfkill-regulator.h):
+ RFKILL_TYPE_ALL
+ RFKILL_TYPE_WLAN
+ RFKILL_TYPE_BLUETOOTH
+ RFKILL_TYPE_UWB
+ RFKILL_TYPE_WIMAX
+ RFKILL_TYPE_WWAN
+ RFKILL_TYPE_GPS
+ RFKILL_TYPE_FM
+ RFKILL_TYPE_NFC
+
+- vrfkill-supply - regulator device.
+
+Example:
+ gps-rfkill {
+ compatible = "rfkill-regulator";
+ label = "GPS";
+ type = <RFKILL_TYPE_GPS>;
+ vrfkill-supply = <®>;
+ };
