    PM / clk: Add support for obtaining clocks from device-tree · 02113ba9
    Jon Hunter authored
    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.
