Subject[PATCH v2 1/3] Bluetooth: hci_qca: Add qca_power_on() API to support both wcn399x and Rome power up
Date
This patch adds a unified API qca_power_on() to support both wcn399x and
Rome power on. For wcn399x it calls the qca_wcn3990_init() to init the
regulators, and for Rome it pulls up the bt_en GPIO to power up the btsoc.
