imp 9cc9119916 Start the retirement process for ufm
This driver hasn't been relevant in almost 15 years. It was for a product on the
shelves for about 6 months in 2003/2004. I've not updated the driver since then,
and have had nobody talk to me about it since maybe 2006 or 2007. It doesn't
implement a standard interface, and can be better done with libusb. All the
action has moved to webcamd for newer, more fully featured hardware. It makes no
appearances in the nycbug dmesg archive.

.Sh NAME
.Nm ufm
.Nd USB driver for Cypress Semiconductor FM Radio
.Sh SYNOPSIS
To compile this driver into the kernel,
place the following line in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device ufm"
.Ed
.Pp
Alternatively, to load the driver as a
module at boot time, place the following line in
.Xr loader.conf 5 :
.Bd -literal -offset indent
ufm_load="YES"
.Ed
.Sh DEPRECATION NOTICE
The
.Nm
driver is not present in
.Fx 13.0
and later.
.Sh DESCRIPTION
The
.Nm
driver provides support for the D-Link/GEMTEK FM tuner.
The USB interface chip is the common Cypress 63001, and the tuner is a
Philips TEA5757 radio chip that uses a serial interface to set the
tuner parameters.
This design is used in the D-Link DSB-R100 USB Radio.
.Pp
The
.Nm
device must be configured in the kernel, along with
.Xr usb 4
and one of the
.Xr uhci 4
or
.Xr ohci 4
controllers.
.Pp
Subsequently, the
.Pa /dev/ufm0
device can be used by userland applications.
