[PATCH v2 0/3] arm64: dts: qcom: enable audio ML offload

[Pratyush Meduri]

The audio ML offload use case on Lemans requires a dedicated contiguous
memory region shared with the audio DSP/SPF as well as corresponding
SMMU stream ID mappings under the EL2 configuration.

This series adds a dedicated CMA pool for audio ML buffers and
associates it with the q6apm audio subsystem. It also updates the ADSP
SMMU configuration in the EL2 overlay to include the ML-related stream
IDs required for DMA transactions during model offload.

Without these changes, audio ML workloads may fail due to unavailable
contiguous memory or SMMU faults caused by unmapped stream IDs.

changes in v2:
 - fixed dt binding issue for iommu.
