* 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>;
|
||
|
|
};
|
||
|
|
};
