I've already applied patch 4 given that Rob had acked the DT bindings changes. I know it's a bit late, but this has been on the list for a couple of months and has Rob's Reviewed-by on the bindings and Will's Acked-by on the ARM SMMU driver patches. If it's too late for v5.18, is there anything else you're waiting for so that this can go into v5.19?
