The + * return value is a u8 which specifies the index corresponding to + * the parent clock. This index can be applied to either the + * .parent_names or .parents arrays. In short, this function + * translates the parent value read from hardware into an array + * index. Currently only called when the clock is initialized by + * __clk_init. This callback is mandatory for clocks with + * multiple parents. It is optional (and unnecessary) for clocks + * with 0 or 1 parents. + * + * @set_parent: Change the input source of this clock; for clocks with multiple + * possible parents specify a new parent by passing in the index + * as a u8 corresponding to the parent in either the .parent_names + * or .parents arrays.
