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.

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.
