I already sent out this patch a couple of months ago, though I realize
that it still hasn't been applied:
http://patchwork.ozlabs.org/project/linux-tegra/list/?series=276030
Joerg, any chance we can still get that series into v5.18? 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?
Thanks,
Thierry
