I am currently working in a custom imx6 sabresd board running on Android Kitkat 4.4.2 with linux kernel 3.0.35. I have interfaced an eGalax USB touchscreen device with my imx6 development kit. The touchscreen works under HID multitouch driver. I would like to configure the Touchscreen to wakeup the imx6 system from the suspend state. Can anyone provide me some information regarding this implementation?
