Subject: [PATCH v2 2/4] arm64: dts: mt8195: Add edptx and dptx nodes
Date: Thu, 15 Sep 2022 17:46:38 +0800	[thread overview]
Message-ID: <20220915094640.5571-3-rex-bc.chen@mediatek.com> (raw)
In-Reply-To: <20220915094640.5571-1-rex-bc.chen@mediatek.com>

In MT8195, we use edptx as the internal display interface and use
dptx as the external display interface. Therefore, we need to add
these nodes to support the internal display and the external display.

- Add dp calibration data in the efuse node.
- Add edptx and dptx nodes for MT8195.
