Subject: [PATCH v7 31/36] drm/rockchip: inno_hdmi: Switch to HDMI connector
Date: Thu, 22 Feb 2024 19:14:17 +0100 [thread overview]
Message-ID: <20240222-kms-hdmi-connector-state-v7-31-8f4af575fce2@kernel.org> (raw)
In-Reply-To: <20240222-kms-hdmi-connector-state-v7-0-8f4af575fce2@kernel.org>
The new HDMI connector infrastructure allows to remove some boilerplate,
especially to generate infoframes. Let's switch to it.
