Subject: [PATCH v3 4/4] arm64: dts: mediatek: cherry: Add edptx and dptx support
Date: Fri, 16 Sep 2022 10:50:59 +0800 [thread overview]
Message-ID: <20220916025059.16673-5-rex-bc.chen@mediatek.com> (raw)
In-Reply-To: <20220916025059.16673-1-rex-bc.chen@mediatek.com>
In cherry projects, we use edptx as the internal display interface
and use dptx as the external display interface. To support this, we
need to add more properties.
- Add pinctrls for edptx and dptx.
- Add ports for edptx and dptx.
The port connections for the internal and external display:
dp-intf0 -> edptx -> panel
dp-intf1 -> dptx
The edptx endpoint is kept empty for now, as the panel addition will
come in a later commit.
