How to enable i2c device of touch screen on channel 0 of LVDS0 in iMX8QM MEK B/D

[hyun-moyang]

Hi All, 

I'd like to enable the I2C device for touch input on Channel 0 of LVDS0 in iMX8QM MEK B/D in android-11.0.0_1.00.

1. How to change the MK file in /device/nxp/imx8q/mek_8q/input-port-association.xml.

    From <port display="1" input="usb-xhci-cdns3-1.2.4/input0" /> to what?

2. For enabling the I2C device for touch input, How I do enable the kernel feature?

Regards

HM
