Subject: [PATCH v3 01/12] dt-bindings: remoteproc: qcom,pas: Add iommus property
Date: Sun, 21 Sep 2025 01:10:59 +0530 [thread overview]
Message-ID: <20250921-kvm_rproc_pas-v3-1-458f09647920@oss.qualcomm.com> (raw)
In-Reply-To: <20250921-kvm_rproc_pas-v3-0-458f09647920@oss.qualcomm.com>
Most Qualcomm platforms feature Gunyah hypervisor which handles IOMMU
configuration for remote processor and when it is not present, the
operating system must perform these configurations instead and for that
firmware stream should be presented to the operating system. Hence, add
iommus property as optional property for PAS supported devices.
