+description: >
+ 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
+
+properties:
+ compatible:
+ const: marvell,dove-divider-clock
+
+ reg:
+ maxItems: 1
+
+ '#clock-cells':
+ const: 1
+
+required:
+ - compatible
+ - reg
+ - '#clock-cells'

+additionalProperties: false

+ reg = <0x0064 0x8>;
