/*
 * 2420 clock tree.
 *
 * NOTE:In many cases here we are assigning a 'default' parent.   In many
 *    cases the parent is selectable.     The get/set parent calls will also
 *    switch sources.
 *
 *    Many some clocks say always_enabled, but they can be auto idled for
 *    power savings. They will always be available upon clock request.
 *
 *    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 periferals 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.

/*
 * This clock is a composite clock which does entire set changes then
 * forces a rebalance. It keys on the MPU speed, but it really could
 * be any key speed part of a set in the rate table.
 *
 * to really change a set, you need memory table sets which get changed
 * in sram, pre-notifiers & post notifiers, changing the top set, without
 * having low level display recalc's won't work... this is why dpm notifiers
 * work, isr's off, walk a list of clocks already _off_ and not messing with
 * the bus.
 *
 * This clock should have no parent. It embodies the entire upper level
 * active set. A parent will mess up some of the init also.
