The TI DA8xx USB0 clk48 clocks implements a mux with a set_parent hook, but doesn't provide a determine_rate implementation.
This is a bit odd, since set_parent() is there to, as its name implies, change the parent of a clock. However, the most likely candidate to trigger that parent change is a call to clk_set_rate(), with determine_rate() figuring out which parent is the best suited for a given rate.
As mentioned in my previous review, parent is selected by device tree and should never be changed after init.
