I've setup my device tree, done all the mappings, i have a 5x8 matrix keyboard i have connected to the kpp, configured for letters a-z and 0-9 plus up down esc enter, but when the OS is running and i have the terminal on my lcd, pressing keys does nothing. I looked in /dev and /proc but i don't see anything anywhere that indicates the keypad is actively being scanned and no letters show up when i press a key. if i run evtest it only shows the power button (tied to the onoff input, not a kpp button) and my touchscreen controller. when the os is starting it does hang for a bit on the message "LSB: preliminary key mapping" but other than that i don't see any indication that the keypad port is setup as a keyboard device in linux.
My device tree dts file is attached, as well as the console output during bootup.
