Subject: [PATCH v1 1/6] dt-bindings: mediatek,dpi: Add mt8195 dpintf
Date: Mon, 6 Sep 2021 21:35:24 +0200 [thread overview]
Message-ID: <20210906193529.718845-2-msp@baylibre.com> (raw)
In-Reply-To: <20210906193529.718845-1-msp@baylibre.com>
DP_INTF is similar to the actual dpi. They differ in some points
regarding registers and what needs to be set but the function blocks
itself are similar in design.
