  35  * 2420 clock tree.

  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.
