+Device Tree Clock bindings for Marvell Berlin
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Clock related registers are spread among the chip control registers. Berlin
+clock node should be a sub-node of the chip controller node. Marvell Berlin2
+(BG2, BG2CD, BG2Q) SoCs share the same IP for PLLs and clocks, with some
+minor differences in features and register layout.
+
+Required properties:
+- compatible: must be "marvell,berlin2-clk" or "marvell,berlin2q-clk"
+- #clock-cells: must be 1
+- clocks: must be the input parent clock phandle
+- clock-names: name of the input parent clock
+ Allowed clock-names for the reference clocks are
+ "refclk" for the SoCs oscillator input on all SoCs,
+ and SoC-specific input clocks for
+ BG2/BG2CD: "video_ext0" for the external video clock input
+
+
+Example:
+
+chip_clk: clock {
+ compatible = "marvell,berlin2q-clk";
+
+ #clock-cells = <1>;
+ clocks = <&refclk>;
+ clock-names = "refclk";
+};
