Which I've forgotten I had already posted as "[PATCH 00/22] SH MTU2 DT 
support" and received a Tested-by for.

I can send a single combined pull request for the driver patches from both 
series (01/22 to 17/22 for MTU2 and 01/52 to 35/52 for CMT/TMU) rebased 
directly on top of v3.15-rc1 when it will be released. Daniel, Thomas, would 
that help, or would you prefer to pick the patches up yourself ?
