IMX8QM SMMU Stream IDs

[josemartins90]

I'm trying to program the SMMU on an imx8qm. However, I can't find in the documentation the list of the stream peripherals for the various DMA devices. Where can I find this information?

Hi josemartins90

all progarmming interfaces are provided with SCU, so one can look

at documentation included in SCFW Porting Kit

Best regards

Thank you. I already found out the call that has to be made to setup the SIDs, howver I am not sure if I need to do something else so that the access doesn't bypass the SMMU.
