Subject: Re: [PATCH v5] Bluetooth: hci_qca: Add qca_power_on() API to support
 both wcn399x and Rome power up

Hi Rocky,

> 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.
> It also moves all the power up operation from hdev->open() to
> hdev->setup().
