- 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.
