0001 * Xtal Clock bindings for Marvell Armada 37xx SoCs
0002
0003 Marvell Armada 37xx SoCs allow to determine the xtal clock frequencies by
0004 reading the gpio latch register.
0005
0006 This node must be a subnode of the node exposing the register address
0007 of the GPIO block where the gpio latch is located.
0008 See Documentation/devicetree/bindings/pinctrl/marvell,armada-37xx-pinctrl.txt

0010 Required properties:
0011 - compatible : shall be one of the following:
0012         "marvell,armada-3700-xtal-clock"
0013 - #clock-cells : from common clock binding; shall be set to 0
0014
0015 Optional properties:
0016 - clock-output-names : from common clock binding; allows overwrite default clock
0017         output names ("xtal")
0018
0019 Example:
0020 pinctrl_nb: pinctrl-nb@13800 {
0021         compatible = "armada3710-nb-pinctrl", "syscon", "simple-mfd";
0022         reg = <0x13800 0x100>, <0x13C00 0x20>;
0023
0024         xtalclk: xtal-clk {
0025                 compatible = "marvell,armada-3700-xtal-clock";
0026                 clock-output-names = "xtal";
0027                 #clock-cells = <0>;
0028         };
0029 };
