Subject: [PATCH v4 2/7] dt-bindings: mediatek,dp: Add Display Port binding
Date: Mon, 11 Oct 2021 11:46:19 +0200 [thread overview]
Message-ID: <20211011094624.3416029-3-msp@baylibre.com> (raw)
In-Reply-To: <20211011094624.3416029-1-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.
