Sylwester Nawrocki	7f05e28f9d	clk: Add of_clk_get_by_clkspec() helper ... This patch adds of_clk_get_by_clkspec() helper function, which does only a struct clk lookup from the clock providers. It is used in the subsequent patch where parsing of a clock from device tree and the lookup from providers needed to be split.

Sylwester Nawrocki	d6782c2636	clk: Provide not locked variant of of_clk_get_from_provider() ... Add helper functions for the of_clk_providers list locking and an unlocked variant of of_clk_get_from_provider(). These functions are intended to be used in the clkdev to avoid race condition in the device tree based clock look up in clk_get().
