This patch adds the different touchscreens that can be connected using the displays available for this board. http://boundarydevices.com/product-category/displays/ Signed-off-by: Gary Bisson <redacted> --- arch/arm/boot/dts/imx6qdl-nitrogen6x.dtsi | 16 ++++++++++++++++ 1 file changed, 16 insertions(+)diff --git a/arch/arm/boot/dts/imx6qdl-nitrogen6x.dtsi b/arch/arm/boot/dts/imx6qdl-nitrogen6x.dtsi index ad16dce..ec9da5e 100644 --- a/arch/arm/boot/dts/imx6qdl-nitrogen6x.dtsi +++ b/arch/arm/boot/dts/imx6qdl-nitrogen6x.dtsi@@ -284,6 +284,22 @@ pinctrl-names = "default"; pinctrl-0 = <&pinctrl_i2c3>; status = "okay"; + + egalax_ts at 04 { + compatible = "eeti,egalax_ts"; + reg = <0x04>; + interrupt-parent = <&gpio1>; + interrupts = <9 2>;
Please use IRQ_TYPE_EDGE_FALLING here.

And that would be GPIO_ACTIVE_HIGH. Should this be changed to GPIO_ACTIVE_LOW instead? From other device tree files and from what the driver does, it looks as if a wakeup is issued by forcing a falling edge on the IRQ pin.
