  34  * 2420 clock tree.
  35  *
  36  * NOTE:In many cases here we are assigning a 'default' parent. In many
  37  *      cases the parent is selectable. The get/set parent calls will also
  38  *      switch sources.
  39  *
  40  *      Many some clocks say always_enabled, but they can be auto idled for
  41  *      power savings. They will always be available upon clock request.
  42  *
  43  *      Several sources are given initial rates which may be wrong, this will
  44  *      be fixed up in the init func.
  45  *
  46  *      Things are broadly separated below by clock domains. It is
  47  *      noteworthy that most periferals have dependencies on multiple clock
  48  *      domains. Many get their interface clocks from the L4 domain, but get
  49  *      functional clocks from fixed sources or other core domain derived
  50  *      clocks.
