14*833e5d42SEmmanuel Vadot  Marvell Dove has a 2GHz PLL, which feeds into a set of dividers to provide
15*833e5d42SEmmanuel Vadot  high speed clocks for a number of peripherals.  These dividers are part of the
16*833e5d42SEmmanuel Vadot  PMU, and thus this node should be a child of the PMU node.
17*833e5d42SEmmanuel Vadot
18*833e5d42SEmmanuel Vadot  The following clocks are provided:
