1* Xtal Clock bindings for Marvell Armada 37xx SoCs
2
3Marvell Armada 37xx SoCs allow to determine the xtal clock frequencies by
4reading the gpio latch register.
5
6This node must be a subnode of the node exposing the register address
7of the GPIO block where the gpio latch is located.
8
9Required properties:
10- compatible : shall be one of the following:
11	"marvell,armada-3700-xtal-clock"
12- #clock-cells : from common clock binding; shall be set to 0
13
14Optional properties:
15- clock-output-names : from common clock binding; allows overwrite default clock
16	output names ("xtal")
17
18Example:
19gpio1: gpio@13800 {
20	compatible = "marvell,armada-3700-gpio", "syscon", "simple-mfd";
21	reg = <0x13800 0x1000>;
22
23	xtalclk: xtal-clk {
24		compatible = "marvell,armada-3700-xtal-clock";
25		clock-output-names = "xtal";
26		#clock-cells = <0>;
27	};
28};
