29.Os
30.Sh NAME
31.Nm rccgpio
32.Nd ADI Engineering RCC-VE and RCC-DFF/DFFv2 GPIO controller
33.Sh SYNOPSIS
34.Cd "device rccgpio"
35.Cd "device gpio"
36.Cd "device gpioled"
37.Sh DESCRIPTION
38The
39.Nm
40provides a simple interface to read the reset switch state and control the
41status LEDs.
42.Pp
43The software controlled reset switch is known to be available on boards from
44Netgate.
45Most people get a button that is a hardware reset.
46.Pp
47All the GPIO pins are locked in their intended setup to disallow any harmful
48settings (the ones that can cause short circuits).
