Subject: Re: [PATCH v5] Bluetooth: hci_qca: Enable power off/on support during
 hci down/up for QCA Rome

Hi Rocky,

> This patch registers hdev->shutdown() callback and also sets
> HCI_QUIRK_NON_PERSISTENT_SETUP for QCA Rome. It will power-off the BT chip
> during hci down and power-on/initialize the chip again during hci up. As
> wcn399x already enabled this, this patch also removed the callback register
> and QUIRK setting in qca_setup() for wcn399x and uniformly do this in the
> probe() routine.
