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:

Acked-by: Simon Horman <horms+renesas@verge.net.au>
