Subject: [PATCH] arm64: dts: qcom: qcs404-evb: Enable uart3 and add Bluetooth
Date: Mon, 4 Mar 2019 23:08:23 -0800 [thread overview]
Message-ID: <20190305070823.11845-1-bjorn.andersson@linaro.org> (raw)
Enable blsp1_uart3, define its pinconf and add the bluetooth node.
It seems provisioning is lacking a valid BD address, preventing the
interface from initializing, so provide a dummy for now.
Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
