Signed-off-by: Vivek Gautam Reviewed-by: Rob Herring Cc: Will Deacon Acked-by: Will Deacon --- Hi Joerg, I am picking this out separately from the sdm845 smmu support series [1], so that this can go through iommu tree. The dt patch from the series [1] can be taken through arm-soc tree. Hi Will, As asked [2], here's the resend version of dt binding patch for sdm845. Kindly ack this so that Joerg can pull this in.
