* 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.
Required properties:
- compatible : shall be one of the following:
- #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")
gpio1: gpio@13800 {
compatible = "marvell,armada-3700-gpio", "syscon", "simple-mfd";
reg = <0x13800 0x1000>;
xtalclk: xtal-clk {
compatible = "marvell,armada-3700-xtal-clock";
clock-output-names = "xtal";
#clock-cells = <0>;
