APPS SMMU is required for address translation in devices including Ethernet/UFS/USB and so on. Add the SCM node for SMMU probing normally. SMMU driver probe will check qcom_scm ready or not, without SCM node, SMMU driver probe will defer. The dmesg log without SCM node: platform 15000000.iommu: deferred probe pending: arm-smmu: qcom_scm not ready With the SCM node, SMMU can probe normally, but SCM driver still fails to probe because of one SCM bug: qcom_scm firmware:scm: error (____ptrval____): Failed to enable the TrustZone memory allocator qcom_scm firmware:scm: probe with driver qcom_scm failed with error 4 The above SCM bug is fixed by: https://lore.kernel.org/all/20241005140150.4109700-2-quic_kuldsing@quicinc.com/ But above patch doesn't impact building of current patch series, this patch series can build successfully without above patch.
