Subject: [PATCH v10 02/21] dt-bindings: mediatek,dp: Add Display Port binding
Date: Mon, 23 May 2022 12:47:35 +0200 [thread overview]
Message-ID: <20220523104758.29531-3-granquet@baylibre.com> (raw)
In-Reply-To: <20220523104758.29531-1-granquet@baylibre.com>
From: Markus Schneider-Pargmann <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.
