35 * 2430 clock tree.
36 *
37 * NOTE:In many cases here we are assigning a 'default' parent. In
38 * many cases the parent is selectable. The set parent calls will
39 * also switch sources.
40 *
41 * Several sources are given initial rates which may be wrong, this will
42 * be fixed up in the init func.
43 *
44 * Things are broadly separated below by clock domains. It is
45 * noteworthy that most peripherals have dependencies on multiple clock
46 * domains. Many get their interface clocks from the L4 domain, but get
47 * functional clocks from fixed sources or other core domain derived
48 * clocks.
