Basically provided for commenting purposes. The patches provide a way to configure clock parents / rates during boot through DT. "default-rate" : sets rate of a clock during boot, supported for any DT clock type (through generic clock driver) "ti,default-parent" : selects a default parent for a multiplexer clock, only supported for TI specific mux clock for now, as generic mux clock does not support DT clocks Patch #4 provided as a reference how to move the default rates / parents from kernel code to DT. Default-rate logic in patch #2 looks somewhat complicated, as the clocks need to be sorted based on their parents to avoid cases where a child clock would set its rate first, just to be overridden by its parent changing rate later and resulting in incorrect rate for the child clock. If the default-rate generic property is not going to fly, it can be moved to TI only drivers also. -Tero
