1* Time Base Generator Clock bindings for Marvell Armada 37xx SoCs
2
3Marvell Armada 37xx SoCs provde Time Base Generator clocks which are
4used as parent clocks for the peripheral clocks.
5
6The TBG clock consumer should specify the desired clock by having the
7clock ID in its "clocks" phandle cell.
8
9The following is a list of provided IDs and clock names on Armada 3700:
10 0 = TBG A P
11 1 = TBG B P
12 2 = TBG A S
13 3 = TBG B S
14
15Required properties:
16- compatible : shall be "marvell,armada-3700-tbg-clock"
17- reg : must be the register address of North Bridge PLL register
18- #clock-cells : from common clock binding; shall be set to 1
19
20Example:
21
22tbg: tbg@13200 {
23	compatible = "marvell,armada-3700-tbg-clock";
24	reg = <0x13200 0x1000>;
25	clocks = <&xtalclk>;
26	#clock-cells = <1>;
27};
