Subject: [PATCH RFC v2 5/5] ARM: dts: qcom: msm8974-hammerhead: add support for external display
Date: Sun, 6 Oct 2019 21:45:09 -0400 [thread overview]
Message-ID: <20191007014509.25180-6-masneyb@onstation.org> (raw)
In-Reply-To: <20191007014509.25180-1-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>
Reviewed-by: Linus Walleij <linus.walleij@linaro.org>

Changes since v1:
- Regulators always on as a temporary haack.
- Hot plug detect pin for the HDMI bridge needs to be low.
