clk_get_by_indexed_prop() retrieves a clock with dev member being set with the pointer to the udevice for the clock controller driver. But in case of CCF each clock driver has set in dev member the reference to its parent (the root of the clock tree is a fixed clock, every node in clock tree is a clock registered with clk_register()). In this case the subsequent operations like dev_get_clk_ptr() on clocks retrieved by clk_get_by_indexed_prop() will fail. For this, get the pointer to the proper clock registered (with clk_register()) using clk_get_by_id() before proceeding.
