As the properties are very general and pertains to all mice I can think of, we use very generic names for the 4-7 GPIO lines, "up", "down" etc. Acked-by: Hans-Christian Noren Egtvedt Cc: devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org Signed-off-by: Linus Walleij --- ChangeLog v1->v2: - Collect Hand-Christian's ACK - Uses 5-7 lines rather than 4-7 lines - Add suffix "-ms" to the scan interval property - Fix compatible string in the example --- .../devicetree/bindings/input/gpio-mouse.txt | 32 ++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 Documentation/devicetree/bindings/input/gpio-mouse.txt diff --git a/Documentation/devicetree/bindings/input/gpio-mouse.txt b/Documentation/devicetree/bindings/input/gpio-mouse.txt new file mode 100644 index 000000000000..519510a11af9 --- /dev/null +++ b/Documentation/devicetree/bindings/input/gpio-mouse.txt @@ -0,0 +1,32 @@ +Device-Tree bindings for GPIO attached mice + +This simply uses standard GPIO handles to define a simple mouse connected +to 5-7 GPIO lines. + +Required properties: + - compatible: must be "gpio-mouse" + - scan-interval-ms: The scanning interval in milliseconds + - up-gpios: GPIO line phandle to the line indicating "up" + - down-gpios: GPIO line phandle to the line indicating "down" + - left-gpios: GPIO line phandle to the line indicating "left" + - right-gpios: GPIO line phandle to the line indicating "right" + +Optional properties: + - button-left-gpios: GPIO line handle to the left mouse button + - button-middle-gpios: GPIO line handle to the middle mouse button + - button-right-gpios: GPIO line handle to the right mouse button +Example: + +#include + +gpio-mouse { + compatible = "gpio-mouse"; + scan-interval-ms = <50>; + up-gpios = <&gpio0 0 GPIO_ACTIVE_LOW>; + down-gpios = <&gpio0 1 GPIO_ACTIVE_LOW>; + left-gpios = <&gpio0 2 GPIO_ACTIVE_LOW>; + right-gpios = <&gpio0 3 GPIO_ACTIVE_LOW>; + button-left-gpios = <&gpio0 4 GPIO_ACTIVE_LOW>; + button-middle-gpios = <&gpio0 5 GPIO_ACTIVE_LOW>; + button-right-gpios = <&gpio0 6 GPIO_ACTIVE_LOW>; +}; -- 2.13.5 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
