Patch "[PATCH v7 4/6] ARM: dts: Exynos: add cpu nodes, opp and cpu clock
configuration data" from Thomas needs another revision anyway since it lacks
cluster ID in Exynos4210 CPU node.  It also mixes addition of CPU nodes
with cpufreq specific changes and IMHO addition of CPU nodes should be in
separate patch to ease bisection if any later problems turn up.  Therefore
I think that it would be the best if Thomas would rebase his work on top of
"irqchip: gic: Fix core ID calculation when topology is read from DT" patch
and this one.  Thomas, are you okay with this?

Best regards,
