+.Sh NAME
+.Nm gdiumiic
+.Nd Gdium specific GPIO I2C controller
+.Sh SYNOPSIS
+.Cd "gdiumiic0 at gpio0 offset 6 mask 0x81"
+.Cd "gdiumiic0 at gpio0 offset 46 mask 0x03"
+.Cd "iic0 at gdiumiic0"
+.Sh DESCRIPTION
+The
+.Nm
+driver allows bit-banging an I2C bus as a master using two GPIO pins.
+The first pin is used as a serial clock (SCL) signal and the second as
+a serial data (SDA).
+Both GPIO pins must be able to drive an output and the SDA pin must be
+also able to read an input.
+.Pp
+The
+.Nm
+driver is derived from the
+.Nm gpioiic
+driver, using a different pin ordering, and knowledge of the Gdium I2C bus
+configuration.
