This patch serie goes on top of https://lore.kernel.org/linux-arm-msm/20201027170033.8475-1-manivannan.sadhasivam@xxxxxxxxxx/ It fixes SMMU issues observed on the RB5 platform when accessing onboard WiFi module. Unfortunately there are no 'Fixes' tags, since original patch series was (partially) accepted but did not hit linux-next (yet).
