    Subject[PATCH 0/2] Common struct clk implementation, v14
    Hi all,

    These patches are an attempt to allow platforms to share clock code. At
    present, the definitions of 'struct clk' are local to platform code,
    which makes allocating and initialising cross-platform clock sources
    difficult, and makes it impossible to compile a single image containing
    support for two ARM platforms with different struct clks.

    The three patches are for the architecture-independent kernel code,
    introducing the common clk infrastructure. The changelog for the first
    patch includes details about the new clock definitions.

    Many thanks to the following for their input:

    * make empty clk_prepare & clk_unprepare static inline

    * Don't expose __clk_get and clk_put - prototypes in clkdev.c instead
    * Add might_sleep to clk_set_rate
    * Comment clarifications & fixups
    * Remove zero initialisers
    * Fold warnings into main clk.c change

    * Always refcount, even when enable/prepare ops are NULL
    * Unify prepare & enable count checking
    * Update comments for prepare/unprepare
    * Use spin_{lock,unlock}_irqsave
    * Change clk_put to __clk_put, and use the shared clk_put

    * add prepare/unprepare for non-atomic switching, document atomicity
    * move to drivers/clk/

    * comment fixups, from Uwe's review
    * added DEFINE_CLK_FIXED

    * comment improvements
    * kerneldoc fixups
    * add WARN_ON to clk_disable

    * add atomic clocks, and locking wrappers
    * expand comments on clk and clk_ops

    * change CLK_INIT to initialise clk->mutex statically

    * fixed up references to 'clk_operations' in the changelog

    * uninline main API, and share definitions with !USE_COMMON_STRUCT_CLK
    * add __clk_get
    * delay mutex init
    * kerneldoc for struct clk

    * use mutex for enable/disable locking
    * DEFINE_CLK -> INIT_CLK, and pass the clk name for mutex init
    * struct clk_operations -> struct clk_ops

    * do clock usage refcounting in common code
    * provide sample port

    * no longer ARM-specific
    * use clk_operations
