How do goodix.c change touch driver to polling touch detection?

Hi @YKL 

I hope you are doing well.

linux-imx/drivers/input/touchscreen/goodix.c driver only supports interrupt mode. the probe will fail if the irq device tree property is not specified.

It is recommended to use interrupt mode on the touchscreen whenever possible.

However, One can try integrating below mentioned driver(out-of kernel tree). which has support for polling mode.

https://github.com/goodix/gt9xx_driver_android/blob/master/gt9xx.c#L1504C6-L1504C6

It will use polling mode if no irq property is specified,
