Hi Linus,

In the follow up the complete patch series without the device tree
modifications. I'll check their upstream separately with Vineet (ARC
platform maintainer) when everything else is applied. Tell me if you
would like to apply the device tree changes yourself nevertheless and
I'll send a patch.

Greetings,
  Christian
