+.Sh NAME
+.Nm mpfgpio
+.Nd Microchip PolarFire SoC MSS GPIO controller
+.Sh SYNOPSIS
+.Cd "mpfgpio* at fdt?"
+.Cd "gpio* at mpfgpio?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the Microchip PolarFire SoC MSS GPIO controller.
+.Pp
+The PolarFire SoC MSS has three GPIO units:
+.Dv GPIO_0 ,
+.Dv GPIO_1
+and
+.Dv GPIO_2 .
+.Dv GPIO_0
+and
+.Dv GPIO_1
+control up to 14 and 24 IOs, respectively.
+These IOs are routed through IOMUXes.
+.Dv GPIO_2
+controls up to 32 IOs through the FPGA fabric.
+.Pp
+The IOs can be configured as either inputs or outputs,
+and accessed using
+.Xr gpioctl 8 .
+.Sh SEE ALSO
+.Xr gpio 4 ,
+.Xr intro 4 ,
+.Xr gpioctl 8
+.Sh HISTORY
+The
+.Nm
+driver first appeared in
+.Ox 7.1 .
