Kernel-4.18.0-80.el8_armada3700-xtal-clock

  • Xtal Clock bindings for Marvell Armada 37xx SoCs

Marvell Armada 37xx SoCs allow to determine the xtal clock frequencies by
reading the gpio latch register.

This node must be a subnode of the node exposing the register address
of the GPIO block where the gpio latch is located.
See Documentation/devicetree/bindings/pinctrl/marvell,armada-37xx-pinctrl.txt

Required properties:

  • compatible : shall be one of the following:
    “marvell,armada-3700-xtal-clock”
  • #clock-cells : from common clock binding; shall be set to 0

Optional properties:

  • clock-output-names : from common clock binding; allows overwrite default clock
    output names (“xtal”)

Example:
pinctrl_nb: pinctrl-nb@13800 {
compatible = “armada3710-nb-pinctrl”, “syscon”, “simple-mfd”;
reg = <0x13800 0x100>, <0x13C00 0x20>;

xtalclk: xtal-clk {
    compatible = "marvell,armada-3700-xtal-clock";
    clock-output-names = "xtal";
    #clock-cells = <0>;
};

};
