Currently there is a mismatch b/w the ICID (Isolation Context ID) used for DMA mapping keys and ICID used for accessing them. -keys are DMA mapped using a job ring device, thus a job ring ICID -keys are accessed from descriptors enqueued via Queue Interface, thus using QI ICID [Note: ICIDs of JRs, QI are configured by U-boot / other entity by: -fixing up the corresponding job ring and controller DT nodes -setting up corresponding caam ICID registers] In order to avoid IOMMU faults, DMA map the key using the controller device instead of a job ring device.
