Subject: [PATCH v4 3/3] Bluetooth: hci_qca: Enable power off/on support during hci down/up for QCA Rome
Date: Wed, 15 Jan 2020 16:55:52 +0800 [thread overview]
Message-ID: <20200115085552.11483-3-rjliao@codeaurora.org> (raw)
In-Reply-To: <20200115085552.11483-1-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. 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.
Signed-off-by: Rocky Liao <rjliao@codeaurora.org>

Changes in v2: None
Changes in v3:
-moved the quirk and callback register to probe()
Changes in v4:
-rebased the patch with latest code
-moved the quirk and callback register to probe() for wcn399x
-updated commit message
