Document the optional reserved memory pool used by platforms where q6apm PCM buffers must be allocated from a predefined carveout instead of from an IOMMU-mapped DMA window. Also document qcom,src-vmid so platforms can describe the VMID that TrustZone tracks as the current owner before qcom_scm_assign_mem() is called. This is needed for S2-only memory that is not initially owned by HLOS. Signed-off-by: Pratyush Meduri <mpratyus@qti.qualcomm.com>
Split the existing audio reserved memory into a shared DMA pool for q6apm and a separate mDSP carveout. Point the q6apm DAI node at the mDSP carveout and share it with the MSS MSA and LPASS VMIDs so the audio path can use the reserved buffer without an IOMMU mapping.
