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