Subject: [RFC v2 10/13] arm64: dts: qcom: qrb5165-rb5: add bluetooth support
Date: Sun, 29 Aug 2021 16:13:02 +0300	[thread overview]
Message-ID: <20210829131305.534417-11-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20210829131305.534417-1-dmitry.baryshkov@linaro.org>

Add support for the bluetooth part of the QCA6391 BT+WiFi chip present
on the RB5 board. WiFi is not supported yet, as it requires separate
handling of the PCIe device power.
