[PATCH 2/4] dt-bindings: display: tegra: Add channel/syncpoint range properties
From: Mikko Perttunen
Date: Mon Jun 22 2026 - 04:28:34 EST
Channels and syncpoints available may be limited when other system
components are using them. Add properties nvidia,channels and
nvidia,syncpoints to limit the range of usable channels and/or
syncpoints.
