Subject: [PATCH v3 2/3] dt-bindings: msm: dsi: document phy-type property for 7nm dsi phy
Date: Tue,  8 Jun 2021 15:53:28 -0400	[thread overview]
Message-ID: <20210608195342.18269-3-jonathan@marek.ca> (raw)
In-Reply-To: <20210608195342.18269-1-jonathan@marek.ca>

Document a new phy-type property which will be used to determine whether
the phy should operate in D-PHY or C-PHY mode.
