Say Y here to enable the Power Sequencing subsystem.
This subsystem is designed to control power to devices that share
complex resources and/or require specific power sequences to be run
during power-up.
If unsure, say no.

help
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.
