1* Peripheral Clock bindings for Marvell Armada 37xx SoCs
2
3Marvell Armada 37xx SoCs provide peripheral clocks which are
4used as clock source for the peripheral of the SoC.
5
6There are two different blocks associated to north bridge and south
7bridge.
8
9The peripheral clock consumer should specify the desired clock by
10having the clock ID in its "clocks" phandle cell.
11
12The following is a list of provided IDs for Armada 370 North bridge clocks:

50Required properties:
51
52- compatible : shall be "marvell,armada-3700-periph-clock-nb" for the
53  north bridge block, or
54  "marvell,armada-3700-periph-clock-sb" for the south bridge block
55- reg : must be the register address of North/South Bridge Clock register
56- #clock-cells : from common clock binding; shall be set to 1
57
58- clocks : list of the parent clock phandle in the following order:
59  TBG-A P, TBG-B P, TBG-A S, TBG-B S and finally the xtal clock.

62Example:
63
64nb_perih_clk: nb-periph-clk@13000{
65	compatible = "marvell,armada-3700-periph-clock-nb";
66	reg = <0x13000 0x1000>;
67	clocks = <&tbg 0>, <&tbg 1>, <&tbg 2>,
68	<&tbg 3>, <&xtalclk>;
69	#clock-cells = <1>;
70};
