| 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. |
