Hello.
I try to implement touchscreen driver. I have resistive touchscreen and this touchscreen used GPIO pin for interrupt on tap. I try to extend my GPIO driver for this. I know how to handle IRQ in driver but I need to send this IRQ event from GPIO driver to touchscreen driver. How to do it? I see only polling from touchscreen driver. Or can I use other solution?
