 * 2430 clock tree.
 *
 * NOTE:In many cases here we are assigning a 'default' parent. In
 *	many cases the parent is selectable. The set parent calls will
 *	also switch sources.
 *
 *	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 peripherals 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.
