Turris Mox Moxtet GPIO expander via Moxtet bus
|
|
|
|
Required properties:
|
|
- compatible : Should be "cznic,moxtet-gpio".
|
|
- gpio-controller : Marks the device node as a GPIO controller.
|
|
- #gpio-cells : Should be two. For consumer use see gpio.txt.
|
|
|
|
Other properties are required for a Moxtet bus device, please refer to
|
|
Documentation/devicetree/bindings/bus/moxtet.txt.
|
|
|
|
Example:
|
|
|
|
moxtet_sfp: gpio@0 {
|
|
compatible = "cznic,moxtet-gpio";
|
|
gpio-controller;
|
|
#gpio-cells = <2>;
|
|
reg = <0>;
|
|
}
