Subject: [PATCH v2 2/6] dt-bindings: mediatek,dp: Add Display Port binding
Date: Mon, 20 Sep 2021 10:44:20 +0200	[thread overview]
Message-ID: <20210920084424.231825-3-msp@baylibre.com> (raw)
In-Reply-To: <20210920084424.231825-1-msp@baylibre.com>

This controller is present on several mediatek hardware. Currently
mt8195 and mt8395 have this controller without a functional difference,
so only one compatible field is added.

The controller can have two forms, as a normal display port and as an
embedded display port.
