On most Qualcomm platforms, the Qualcomm Hypervisor Execution Environment (QHEE) is either used as a standalone hypervisor or co-exists as a module with the Gunyah hypervisor. When QHEE is present, it configures firmware streams for remote processors. If QHEE is not available, the operating system must perform these configurations instead and for that remote processor firmware stream should be presented to the operating system. To support this, add the iommus property as an optional property for PAS-supported devices.
