    Subject[PATCH v2 0/7] Add a generic struct clk
    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,

    Mark's re-post (v1+) can be found at,

    Todo in follow-up patches:
    Implement a *safe* upstream propagation for parent rate changes
    Track tree topology and export to userspace (sysfs or debugfs)
    Manage root clocks globally
    Device tree support
    Per-tree locking instead of framework-wide locking
    Device driver rate-change notifiers

    Jeremy Kerr (4):
    clk: Add a generic clock infrastructure
    clk: Implement clk_set_rate
    clk: Add fixed-rate clock
    clk: Add simple gated clock

    Mark Brown (3):
    clk: Add Kconfig option to build all generic clk drivers
    clk: Add initial WM831x clock driver
    x86: Enable generic clk API on x86
