Subject: Re: [PATCH v9 02/22] dt-bindings: mediatek, dp: Add Display Port binding
Date: Wed, 30 Mar 2022 13:12:02 +0800 [thread overview]

In-Reply-To: <20220327223927.20848-3-granquet@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
