The ADSP PAS on several Qualcomm SoCs (e.g. SA8775P/lemans, QCS8300, Monaco) needs more than a single SMMU stream ID for the audio ML (machine-learning) offload use case. In addition to the primary ADSP stream ID, the DSP/SPF issues DMA transactions through extra stream IDs that are not covered by the existing single-entry mapping.
Relax the iommus constraint to allow between 1 and 3 entries so the additional ML offload stream IDs can be described, fixing dtb_check schema violations on device trees that add them.
