Subject: [PATCH v1 1/4] Bluetooth: hci_qca: Add QCA Rome power off support to the qca_power_off()
Date: Wed, 25 Dec 2019 14:03:14 +0800
Message-ID: <20191225060317.5258-1-rjliao@codeaurora.org> (raw)

We will need to call the qca_power_off() API to power off Rome, add the
support into it. QCA Rome is using bt_en GPIO for power off, so we just
need to pull down this bt_en GPIO to power off it.
