[1/2] arm64: dts: qcom: sm6115: add iommu for sdhc_1 commit: 94ea124aeefe1ef271263f176634034e22c49311 Best regards,
Add the missing iommus property on the first sdhc, and set a default mode for USB role switch. The iommus property in particular is necessary when running U-Boot as a first-stage bootloader, since it can't rely on EDK2 to configure the SMMU and crashes with: [020b9ed0d]TLB Dump Message:Not a valid memory address to dump TLBs for device APPS_TCU or no memory available.
