Subject: [PATCH v2] ARM: sun8i: h3: bluetooth for Banana Pi M2 Zero board
Date:   Fri,  1 Mar 2019 19:52:12 +0100
Message-Id: <20190301185212.26837-1-andreas@kemnade.info>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The Banana Pi M2 Zero board has an AP6212 BT+Wifi combo chip
with broadcom internals attached to UART1 and some gpios.
This addition is in line with similar boards
