I patched them all and changes are queued through arm-soc, according to the
latest bindings that should get merged this cycle and are available here:

git://linux-arm.org/linux-2.6-lp.git dt-cpus-bindings

If you are queuing dts updates please follow rules in there, waiting for
that document to get merged.
