40 * NOTE:In many cases here we are assigning a 'default' parent. In
41 * many cases the parent is selectable. The set parent calls will
42 * also switch sources.
43 *
44 * Several sources are given initial rates which may be wrong, this will
45 * be fixed up in the init func.
46 *
47 * Things are broadly separated below by clock domains. It is
48 * noteworthy that most peripherals have dependencies on multiple clock
49 * domains. Many get their interface clocks from the L4 domain, but get
50 * functional clocks from fixed sources or other core domain derived
