Subject: [PATCH v3 1/3] arm64: dts: apq8096-db820c: enable bluetooth node
Date: Tue, 13 Mar 2018 19:38:05 +0100 [thread overview]
Message-ID: <20180313183807.6701-2-thierry.escande@linaro.org> (raw)
In-Reply-To: <20180313183807.6701-1-thierry.escande@linaro.org>
Add a new serial node for the Qualcomm BT controller QCA6174. This
allows automatic probing and hci registration through the serdev
framework instead of relying on the userspace helpers.
