-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";
-};
