tristate "Power Sequencing support"
help
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.

help
Say Y here to enable the power sequencing driver for the TH1520 SoC
GPU. This driver handles the complex clock and reset sequence
required to power on the Imagination BXM GPU on this platform.
