I want to use matrix-keypad with beaglebone black.I completed these steps:
1.Modprobe matrix_keypad
*output of zcat /proc/config.gz | grep MATRIX*
CONFIG_INPUT_MATRIXKMAP=m
CONFIG_KEYBOARD_MATRIX=m
I am looking into am335x-evm.dts
It has pin settings as:
matrix_keypad@0 {
compatible = "gpio-matrix-keypad";
debounce-delay-ms = <0x5>;
col-scan-delay-us = <0x2>;
row-gpios = <0x5a 0x19 0x0 0x5a 0x1a 0x0 0x5a 0x1b 0x0>;
col-gpios = <0x5a 0x15 0x0 0x5a 0x16 0x0>;
linux,keymap = <0x8b 0x100009e 0x2000069 0x1006a 0x101001c 0x201006c>;
linux,phandle = <0xdd>;
phandle = <0xdd>;
};
How can I use this information in *am335x-boneblack-emmc-overlay.dts *
Please guide me:
