From d84790afce7f4dbe70954adef8ab12f7b36f125e Mon Sep 17 00:00:00 2001 From: Vishnu Reddy Date: Wed, 10 Jun 2026 11:59:39 +0530 Subject: [PATCH] dt-bindings: media: qcom,glymur-iris: Add glymur video codec Add device tree binding for the Qualcomm Glymur Iris video codec. Glymur is a new generation of video IP that introduces a dual-core architecture. The second core brings its own power domain, clocks, and reset lines, requiring additional power domains and clocks in the power sequence. The current maxItems constraints for clocks and power-domains in the common venus schema were sized for platforms available at the time of authoring. The glymur platform introduces a dual core architecture that requires more clocks and power domains, exceeding these limits. Raise maxItems for clocks, clock-names, power-domains and power-domain-names to accommodate the glymur platform. The glymur platform-specific schema have fixed constraints for these properties, so the common schema only acts as an upper bound.
