+IWCONFIG COMMANDS
+========================
+power period
+
+        This command is used to configure the station in deep sleep mode /
+        auto deep sleep mode.
+
+        The timer is implemented to monitor the activities (command, event,
+        etc.). When an activity is detected station will exit from deep
+        sleep mode automatically and restart the timer. At timer expiry
+        (no activity for defined time period) the deep sleep mode is entered
+        automatically.
+
+        Note: this command is for SDIO interface only.
+
+        Usage:
+        To enable deep sleep mode do:
+                iwconfig wlan0 power period 0
+        To enable auto deep sleep mode with idle time period 5 seconds do:
+                iwconfig wlan0 power period 5
+        To disable deep sleep/auto deep sleep mode do:
+                iwconfig wlan0 power period -1
