  • 498b5fdd4   PM / clk: Add support for adding a specific clock from device-tree ... Browse Code »

    Some drivers using the PM clocks framework need to add specific clocks
    from device-tree using a name by calling the functions
    of_clk_get_by_name() and then pm_clk_add_clk(). Rather than having
    drivers call both functions, add a helper function of_pm_clk_add_clk()
    that will call these functions so drivers can call a single function
    to add a specific clock from device-tree.

  • 02113ba93   PM / clk: Add support for obtaining clocks from device-tree ... Browse Code »

    The PM clocks framework requires clients to pass either a con-id or a
    valid clk pointer in order to add a clock to a device. Add a new
    function of_pm_clk_add_clks() to allows device clocks to be retrieved
    from device-tree and populated for a given device. Note that it is
    not necessary to make the compilation of this new function dependent
    upon CONFIG_OF because there are stubs functions for the device-tree
    APIs used.

    In order to handle errors encountered when adding clocks from
    device-tree, add a function pm_clk_remove_clk() to remove any clocks
    (using a pointer to the clk structure) that have been added
    successfully before the error occurred.

    Most users of PM clocks do the extact same things in the runtime
    suspend/resume callbacks. Provide them USE_PM_CLK_RUNTIME_OPS so
    as to avoid/remove boilerplate code.

    The existing pm_clk_add() allows to pass a clock by con_id. However,
    when referring to a specific clock from DT, no con_id is available.

    Add pm_clk_add_clk(), which allows to specify the struct clk * directly.
    The will will increment refcount on clock pointer, so the caller has
    to use clk_put() on clock pointer when done.
