[PATCH 1/4] dt-bindings: dma: Update ADMA bindings for tegra264

From: Sheetal . <hidden>
Date: 2025-09-18 10:20:54
Also in: dmaengine, linux-devicetree, linux-sound, linux-tegra, lkml
Subsystem: dma generic offload engine subsystem, open firmware and flattened device tree bindings, the rest · Maintainers: Vinod Koul, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

From: sheetal <redacted>

- Update ADMA device tree bindings for tegra264 to support up to 64
  interrupt channels by setting 'interrupts' property maxItems to 64.
- Also, update the 'allOf' conditional schema to ensure correct maxItems
  for 'interrupts' based on compatible string, including tegra210 (22)
  and tegra186 (32) ADMA controllers.
