[PATCH v5] arm64: dts: qcom: shikra: Add ICE, TRNG and QCE nodes
From: Kuldeep Singh
Date: Thu Aug 20 2026 - 06:54:01 EST
Add device tree nodes describing the crypto hardware blocks present
on the Qualcomm Shikra platform:
- BAM DMA controller used by the Qualcomm crypto engine
- QCE (crypto) engine with DMA support
- TRNG hardware random number generator
- Inline crypto engine (ICE)
Also connect the SDHC controller to ICE via "qcom,ice" property to
support inline encryption.
On Shikra, different BAM pipe pairs (for example 0x84/0x94 and
0x86/0x96) may still resolve to the same resulting SID due SMMU-side
optimization. They are still distinct pipe pairs and therefore require
separate DT IOMMU entries.

This patch series enables SDHC ICE, RNG and QCE support on Shikra,
aligned with how similar support is modeled on other Qualcomm platforms.
Keeping just dts patch as rest all patches got merged.
