 * 2420 clock tree.
 *
 * NOTE:In many cases here we are assigning a 'default' parent.	In many
 *	cases the parent is selectable.	The get/set parent calls will also
 *	switch sources.
 *
 *	Many some clocks say always_enabled, but they can be auto idled for
 *	power savings. They will always be available upon clock request.
 *
 *	Several sources are given initial rates which may be wrong, this will
 *	be fixed up in the init func.
 *
 *	Things are broadly separated below by clock domains. It is
 *	noteworthy that most periferals have dependencies on multiple clock
 *	domains. Many get their interface clocks from the L4 domain, but get
 *	functional clocks from fixed sources or other core domain derived
 *	clocks.
