Subject: [PATCH v3 3/4] Bluetooth: hci_qca: Enable power off/on support during hci down/up for QCA Rome
Date: Fri, 27 Dec 2019 15:21:29 +0800 [thread overview]
Message-ID: <20191227072130.29431-3-rjliao@codeaurora.org> (raw)
In-Reply-To: <20191227072130.29431-1-rjliao@codeaurora.org>
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.
Signed-off-by: Rocky Liao <rjliao@codeaurora.org>

Changes in v2: None
