+PLL divider based Dove clocks
+
+Marvell Dove has a 2GHz PLL, which feeds into a set of dividers to provide
+high speed clocks for a number of peripherals. These dividers are part of
+the PMU, and thus this node should be a child of the PMU node.
+
+The following clocks are provided:
+
+ID Clock
+-------------
+0 AXI bus clock
+1 GPU clock
+2 VMeta clock
+3 LCD clock
+
+Required properties:
+- compatible : shall be "marvell,dove-divider-clock"
+- reg : shall be the register address of the Core PLL and Clock Divider
+ Control 0 register. This will cover that register, as well as the
+ Core PLL and Clock Divider Control 1 register. Thus, it will have
+ a size of 8.
+- #clock-cells : from common clock binding; shall be set to 1
+
+divider_clk: core-clock@64 {
+ compatible = "marvell,dove-divider-clock";
+ reg = <0x0064 0x8>;
+ #clock-cells = <1>;
+};
