I'm not sure I understand your question. The conflicts that Russell
mentioned are with the ux500/timer (in next/soc) and with the
vexpress/dt (in next/dt) branches. There are multiple ways out of
here:

a) take your series first, but merge it into the next/dt and next/soc
   branches, resolving the conflicts in the process. This would be
   fairly easy to do if you can provide the merge resolution as
   a git pull and let Russell still take your series as is.

b) rebase your series on top of vexpress/dt, merge it into the next/soc
   branch.

c) rebase your series on top of ux500/timer, merge it into the next/dt
   branch.

d) create a new next/timer branch in arm-soc that has Pawel's     
   98ed4ceb "ARM: vexpress: Get rid of MMIO_P2V" (the first patch from
   vexpress/dt, your patches and the ux500/timer series. Also put
   98ed4ceb into the next/cleanup branch.

Any of those will work for us, my preference would be on #4. I have
created the next/timer branch in the arm-soc tree, so you can use
that and either rebase your patches on top or merge your tree into
it and fix up the merge conflicts.
