Subject: [PATCH v13 2/6] dt-bindings: display: mediatek: control dpi pins mode to avoid leakage
Date: Wed, 11 Mar 2020 15:18:19 +0800 [thread overview]
Message-ID: <20200311071823.117899-3-jitao.shi@mediatek.com> (raw)
In-Reply-To: <20200311071823.117899-1-jitao.shi@mediatek.com>
Add property "pinctrl-names" to swap pin mode between gpio and dpi mode. Set
the dpi pins to gpio mode and output-low to avoid leakage current when dpi
disabled.
