V4L/DVB (6656): zl10353: store frequencies in 0.1kHz to eliminate rounding errors
[linux-2.6] / drivers / media / dvb / dvb-usb / cxusb.c
1 /* DVB USB compliant linux driver for Conexant USB reference design.
2  *
3  * The Conexant reference design I saw on their website was only for analogue
4  * capturing (using the cx25842). The box I took to write this driver (reverse
5  * engineered) is the one labeled Medion MD95700. In addition to the cx25842
6  * for analogue capturing it also has a cx22702 DVB-T demodulator on the main
7  * board. Besides it has a atiremote (X10) and a USB2.0 hub onboard.
8  *
9  * Maybe it is a little bit premature to call this driver cxusb, but I assume
10  * the USB protocol is identical or at least inherited from the reference
11  * design, so it can be reused for the "analogue-only" device (if it will
12  * appear at all).
13  *
14  * TODO: Use the cx25840-driver for the analogue part
