Subject: [PATCH RFC 11/11] ARM: dts: qcom: msm8974-hammerhead: add support for external display
Date: Wed, 14 Aug 2019 20:48:54 -0400 [thread overview]
Message-ID: <20190815004854.19860-12-masneyb@onstation.org> (raw)
In-Reply-To: <20190815004854.19860-1-masneyb@onstation.org>
Add HDMI nodes and other supporting infrastructure in order to support
the external display. This is based on work from Jonathan Marek.
Signed-off-by: Brian Masney <masneyb@onstation.org>
