[PATCH 6.1 211/224] arm64: dts: qcom: sm8150: Fix the iommu mask used for PCIe controllers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


From: Manivannan Sadhasivam <manivannan.sadhasivam@xxxxxxxxxx>

commit 672a58fc7c477e59981653a11241566870fff852 upstream.

The iommu mask should be 0x3f as per Qualcomm internal documentation.
Without the correct mask, the PCIe transactions from the endpoint will
result in SMMU faults. Hence, fix it!
