I am trying to interface 4X4 keypad with i-MX6 solo , but I don;t have much idea on it. I am using linux 3.14.28 kernel.
Do I need to modify the driver matrix_keypad.c in linux kernel ?
Do I need to modify the Device Tree File?
If any one has already done this then please guide me or share your suggestions to interface 4x4 keypad with i-MX6 solo
