Linux uses the properties 'assigned-clocks', 'assigned-clock-parents' and 'assigned-clock-rates' to configure the clock subsystem for use with various peripheral nodes.
This implements clk_set_defaults() and hooks it up with the general device probibin in drivers/core/device.c: when a new device is probed, clk_set_defaults() will be called for it and will process the properties mentioned above.
Note that this functionality is designed to fail gracefully (i.e. if a clock-driver does not implement set_parent(), we simply accept this and ignore the error) as not to break existing board-support.

Applied to u-boot-rockchip, thanks!
Is the right thing to do to apply a general change without more review?
