+* Time Base Generator Clock bindings for Marvell Armada 37xx SoCs
+
+Marvell Armada 37xx SoCs provde Time Base Generator clocks which are
+used as parent clocks for the peripheral clocks.
+
+The TBG clock consumer should specify the desired clock by having the
+clock ID in its "clocks" phandle cell.
+
+The following is a list of provided IDs and clock names on Armada 3700:
+ 0 = TBG A P
+ 1 = TBG B P
+ 2 = TBG A S
+ 3 = TBG B S
+
+Required properties:
+- compatible : shall be "marvell,armada-3700-tbg-clock"
+- reg : must be the register address of North Bridge PLL register
+- #clock-cells : from common clock binding; shall be set to 1
+
+Example:
+
+tbg: tbg@13200 {
+       compatible = "marvell,armada-3700-tbg-clock";
+       reg = <0x13200 0x1000>;
+       clocks = <&xtalclk>;
+       #clock-cells = <1>;
+};
