+.Nd Global Mixed-mode Technology Inc. G760a fan speed controller driver
+.Sh SYNOPSIS
+.Cd g760a0 at iic? addr 0x3e
+.Pp
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the
+.Tn Global Mixed-mode Technology Inc
+G760a on iicbus fan speed controller to be used with the
+.Xr envsys 4
+API. This chip could be found in
+.Tn D-Link's DNS-323 NAS box.
+.Pp
+The following
+.Xr sysctl 8
+variable control the fan's speed:
+.Bl -tag
+.It Dv machdep.g760a0.rpm
+This value specifies the desired speed for the fan.
+Valid range is 2000..20000 or 0 (the fan is turned off).
+The default value is 0.
+.Pp
+When setting the desired speed the RPM number will be converted
+to the internal represenation and truncated. For example when you
+are setting 2000 it will be truncated to 2006, and 8000 will be
+changed to 8057.
