Hi Guennadi, Hi all,
I apologise for not replying earlier.
I am happy to take these changes through my renesas tree and request they be pulled into the arm-soc tree provided that there are acks from Vinod and Chris on the relevant patches.
I am also happy for either Chris or Vinod to take the patches.
To that end, for the two smhobile patches below:
