Mike Turquette picked up the work several months ago, and has posted
4 versions since then.  The following branch has the latest version.

http://git.linaro.org/gitweb?p=people/mturquette/linux.git;a=shortlog;h=refs/heads/v3.2-rc5-clkv4

Richard Zhao has been closely tracking the work to have imx5 clock
migrated to it.  And the latest code can be found on the branch below.
