Subject: [PATCH v3 3/3] arm64: allwinner: Enable Bluetooth and WiFi on sopine baseboard
Date:   Sat, 11 Apr 2020 19:06:44 -0700
Message-Id: <20200412020644.355142-3-alistair@alistair23.me>
In-Reply-To: <20200412020644.355142-1-alistair@alistair23.me>
References: <20200412020644.355142-1-alistair@alistair23.me>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-bluetooth-owner@vger.kernel.org
Precedence: bulk

The sopine board has an optional RTL8723BS WiFi + BT module that can be
connected to UART1. Add this to the device tree so that it will work
for users if connected.
