Subject: [PATCH] bluetooth: Add flag to define wideband speech capability
Date:   Mon, 24 Feb 2020 15:03:29 +0000
Message-Id: <20200224150329.166662-1-alainm@chromium.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-bluetooth-owner@vger.kernel.org
Precedence: bulk

This change adds a new flag to define a controller's wideband speech
capability.  This is required since no reliable over HCI mechanism
exists to query the controller and driver's compatibility with
wideband speech.
