I am working on imx6ul using linux yocto. I want to use imx6 keypad port. I have enabled it in imx6ul.dtsi.
But I just want to use 4x4 keypad instead of 8x8 as defined by kpp.
what changes I would have to make to do it 4x4 in device tree?
I am reading AN5125 -Introduction to device tree but not getting how to change it. Please help.
