Subject: [PATCH v8 6/7] ARM: dts: imx: Add TDA19971 HDMI Receiver to GW54xx
Date:   Tue,  6 Feb 2018 12:27:53 -0800
Message-Id: <1517948874-21681-7-git-send-email-tharvey@gateworks.com>
In-Reply-To: <1517948874-21681-1-git-send-email-tharvey@gateworks.com>
References: <1517948874-21681-1-git-send-email-tharvey@gateworks.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The GW54xx has a front-panel microHDMI connector routed to a TDA19971
which is connected the the IPU CSI when using IMX6Q.

Signed-off-by: Tim Harvey <tharvey@gateworks.com>
