Hi all,
The goal of this series is to provide a cross-platform clock framework that platforms can use to model their clock trees and perform common operations on them. Currently everyone re-invents their own clock tree inside platform code which makes it impossible for drivers to use the clock APIs safely across many platforms and for distro's to compile multi-platform kernels which all redefine struct clk and its operations.
This is the second version of the common clock patches which were originally posted by Jeremy Kerr and then re-posted with some additional patches by Mark Brown. Mark's re-post didn't have any changes done to the original four patches from Jeremy which is why this series is "v2".
The changes in this series are minimal: I've folded in some of Mark's fixes and most of the comments posted to his series as well as rebasing on top of v3.1-rc7. The design and functionality hasn't changed much since Jeremy posted v1 of this series. Propagating the rate change up to the parent has been removed from clk_set_rate since that needs some more thought. I also dropped Mark's change to append a device's name to a clk name since device tree might solve this neatly. Again more discussion around that would be good.
v1 of the series can be found at, http://article.gmane.org/gmane.linux.kernel/1143182
Mark's re-post (v1+) can be found at, http://article.gmane.org/gmane.linux.ports.arm.kernel/129889
Looks good at first review to me. I had a few comments, but nothing major. It really needs some documentation though.
