[PATCH v2 04/13] dt-bindings: media: qcom,glymur-iris: Add glymur video codec

Vishnu Reddy
2026-04-23T13:30:34Z

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.
