Subject: [PATCH v3 1/3] dt-bindings: display: tegra: document EPP, ISP, MPE and TSEC for Tegra114 and Tegra124
The current EPP, ISP and MPE schemas are largely compatible with Tegra114
and Tegra124, requiring only minor adjustments. Additionally, the TSEC
schema for the Security engine, which is available from Tegra114 onwards,
is included.
