Help text

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

Typically, a package from the Qualcomm WCN family contains the BT and WLAN modules whose power is controlled by the PMU module. As the former two share the power-up sequence which is executed by the PMU, this driver is needed for correct power control or else we'd risk not respecting the required delays between enabling Bluetooth and WLAN.
