Subject: [PATCH 06/38] dt-bindings: display: tegra: Document display-hub
Date: Fri, 12 Jun 2020 16:18:31 +0200 [thread overview]
Message-ID: <20200612141903.2391044-7-thierry.reding@gmail.com> (raw)
In-Reply-To: <20200612141903.2391044-1-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
Tegra186 and later have an additional component in the display pipeline
called the display hub. Document the bindings which were missing.
