FROMLIST: media: iris: Enable Secure PAS support with IOMMU managed b…

[gouravk-qualcomm]

Most Qualcomm platforms feature a inhouse hypervisor (such as Gunyah or QHEE), which typically handles IOMMU configuration. This includes mapping memory regions and device memory resources for remote processors by intercepting qcom_scm_pas_auth_and_reset() calls. These mappings are later removed during teardown. Additionally, SHM bridge setup is required to enable memory protection for both remoteproc metadata and its memory regions.

When the hypervisor is absent, the operating system must perform these configurations instead.

Support for handling IOMMU and SHM setup in the absence of a hypervisor is now in place. Extend the Iris driver to enable this functionality on platforms where IOMMU is managed by Linux (i.e., non-Gunyah, non-QHEE).

Additionally, the Iris driver must map the firmware and its required resources to the firmware SID, which is now specified via the device tree.
