[PATCH 4/9] iommu/arm-smmu-qcom: Request direct mapping for modem device

From: Sibi Sankar <hidden>
Date: 2021-06-24 19:48:48
Also in: linux-arm-msm, linux-remoteproc, lkml
Subsystem: arm smmu drivers, iommu subsystem, qualcomm iommu, the rest · Maintainers: Will Deacon, Joerg Roedel, Rob Clark, Linus Torvalds

The SID configuration requirement for Modem on SC7280 is similar to the
ones found on SC7180/SDM845 SoCs. So, add the SC7280 modem compatible to
the list to defer the programming of the modem SIDs to the kernel.
