+.Sh NAME
+.Nm mpl115a
+.Nd Freescale MPL115A2 absolute pressure sensor driver
+.Sh SYNOPSIS
+.Cd "mpl115a* at iic? addr 0x60"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the MPL115A2 pressure sensor.
+It allows reporting absolute pressure through the
+.Xr envsys 4
+API.
+.Sh SEE ALSO
+.Xr envsys 4
+.Sh HISTORY
+The
+.Nm
+device first appeared in
+.Nx 7.0 .
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm
+driver was written by
+.An Radoslaw Kujawa Aq radoslaw.kuj...@gmail.com .
+The fixed-point pressure calculation algorithm was suggested by
+.An Matt Thomas .
+.Sh CAVEATS
+The MPL115A2 chip has an accuracy of +/- 1 kPa, which makes it not very useful
+for weather-related applications.
+.Pp
+The
+.Xr envsys 4
+API does not support pressure reporting yet, so the result is reported just as
+integer number.
