It's useful to have tracepoints around operations that change the hardware state so that we can debug clock hardware performance and operations. Four basic types of events are supported: on/off events for enable, disable, prepare, unprepare that only record an event and a clock name, rate changing events for clk_set_{min_,max_}rate{_range}(), phase changing events for clk_set_phase() and parent changing events for clk_set_parent().
