21 Say Y here to enable the power sequencing driver for Qualcomm
22 WCN Bluetooth/WLAN chipsets.
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.
