All DTS patches shall be merged through ARM SoC so the conflict should
be resolved by whoever sends the pull requests to ARM SoC before
sending the pull request.

I think these patches will be for the next kernel anyways, unless Torvalds
think we should have an -rc9 this time (because of all the meltdowns and
spectres etc you know).
