Subject: [PATCH v4 2/3] dt-bindings: remoteproc: qcom,shikra-pas: Add iommus constraints
Date: Wed, 04 Nov 2026 19:33:31 +0530 [thread overview]
Message-ID: <20261104-shikra-el2-v4-2-97e7019debff@oss.qualcomm.com> (raw)
In-Reply-To: <20261104-shikra-el2-v4-0-97e7019debff@oss.qualcomm.com>
Add iommus constraints for Shikra PAS compatible:
- qcom,shikra-cdsp-pas: maxItems: 1
- qcom,shikra-lpaicp-pas: minItems: 3, maxItems: 3
CDSP uses single IOMMU stream, while LPAICP firmware uses three.
These are needed to describe the firmware streams when Linux boots
at EL2 without the hypervisor.
