Subject: [PATCH v10 03/27] drm/connector: hdmi: Create an HDMI sub-state
Date: Thu, 21 Mar 2024 16:28:59 +0100 [thread overview]
Message-ID: <20240321-kms-hdmi-connector-state-v10-3-e6c178361898@kernel.org> (raw)
In-Reply-To: <20240321-kms-hdmi-connector-state-v10-0-e6c178361898@kernel.org>
The next features we will need to share across drivers will need to
store some parameters for drivers to use, such as the selected output
format.
Let's create a new connector sub-state dedicated to HDMI controllers,
that will eventually store everything we need.
