21	  Say Y here to enable the power sequencing driver for Qualcomm
22	  WCN Bluetooth/WLAN chipsets.
23
24	  Typically, a package from the Qualcomm WCN family contains the BT
25	  and WLAN modules whose power is controlled by the PMU module. As the
26	  former two share the power-up sequence which is executed by the PMU,
27	  this driver is needed for correct power control or else we'd risk not
28	  respecting the required delays between enabling Bluetooth and WLAN.
