+ * @user_claim_unsupported: Whether the hardware supports exclusive
+ *	RF-kill control by userspace. Set this before registering.
+ * @user_claim: Set when the switch is controlled exlusively by userspace.
+ * @mutex: Guards switch state transitions.  It serializes callbacks
+ *	and also protects the state.
+ * @data: Pointer to the RF button drivers private data which will be
+ *	passed along when toggling radio state.
+ * @toggle_radio(): Mandatory handler to control state of the radio.
+ *	only RFKILL_STATE_SOFT_BLOCKED and RFKILL_STATE_UNBLOCKED are
+ *	valid parameters.
+ * @get_state(): handler to read current radio state from hardware,
+ *      may be called from atomic context, should return 0 on success.
+ *      Either this handler OR judicious use of rfkill_force_state() is
+ *      MANDATORY for any driver capable of RFKILL_STATE_HARD_BLOCKED.
+ * @led_trigger: A LED trigger for this button's LED.
+ * @dev: Device structure integrating the switch into device tree.
+ * @node: Used to place switch into list of all switches known to the
+ *	the system.
+ *
+ * This structure represents a RF switch located on a network device.
