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. 8See Documentation/devicetree/bindings/pinctrl/marvell,armada-37xx-pinctrl.txt 9 10Required properties: 11- compatible : shall be one of the following: 12 "marvell,armada-3700-xtal-clock" 13- #clock-cells : from common clock binding; shall be set to 0 14 15Optional properties: 16- clock-output-names : from common clock binding; allows overwrite default clock 17 output names ("xtal") 18 19Example: 20pinctrl_nb: pinctrl-nb@13800 { 21 compatible = "armada3710-nb-pinctrl", "syscon", "simple-mfd"; 22 reg = <0x13800 0x100>, <0x13C00 0x20>; 23 24 xtalclk: xtal-clk { 25 compatible = "marvell,armada-3700-xtal-clock"; 26 clock-output-names = "xtal"; 27 #clock-cells = <0>; 28 }; 29};
