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. This function in affect translates an + * array index into the value programmed into the hardware. + * Returns 0 on success, -EERROR otherwise. + * + * @set_rate: Change the rate of this clock. The requested rate is specified + * by the second argument, which should typically be the return + * of .round_rate call. The third argument gives the parent rate + * which is likely helpful for most .set_rate implementation. + * Returns 0 on success, -EERROR otherwise. + * + * The clk_enable/clk_disable and clk_prepare/clk_unprepare pairs allow + * implementations to split any work between atomic (enable) and sleepable + * (prepare) contexts. If enabling a clock requires code that might sleep, + * this must be done in clk_prepare. Clock enable code that will never be + * called in a sleepable context may be implement in clk_enable. + * + * Typically, drivers will call clk_prepare when a clock may be needed later + * (eg. when a device is opened), and clk_enable when the clock is actually + * required (eg. from an interrupt).
