I have successfully compiled .dts file into .dtb file including these

matrix_keypad = "/matrix_keypad@0";
*But I am unable to understand these lines:*
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>;
I want to use pins P8_39 - P8_46 as matrix keypad, How can I map these pins
to above hex values.
