V4L/DVB (7786): cx18: new driver for the Conexant CX23418 MPEG encoder chip 

Many thanks to Steve Toth from Hauppauge and Nattu Dakshinamurthy from
Conexant for their support. I am in particular thankful to Hauppauge
since without their help this driver would not exist. It should also
be noted that Steve did the work to get the DVB part up and running.
Thank you!

Some notes regarding the cx18 driver for the Conexant CX23418 MPEG
encoder chip:
1) The only hardware currently supported is the Hauppauge HVR-1600.
2) Some people have problems getting the i2c bus to work. Cause unknown.
The symptom is that the eeprom cannot be read and the card is
unusable.
3) The audio from the analog tuner is mono only. Probably caused by
incorrect audio register information in the datasheet. We are
waiting for updated information from Conexant.
4) VBI (raw or sliced) has not yet been implemented.
5) MPEG indexing is not yet implemented.
6) The driver is still a bit rough around the edges, this should
improve over time.
Firmware:
The firmware needs to be extracted from the Windows Hauppauge HVR-1600
driver, available here:
http://hauppauge.lightpath.net/software/install_cd/hauppauge_cd_3.4d1.zip
Unzip, then copy the following files to the firmware directory
and rename them as follows:
Drivers/Driver18/hcw18apu.rom -> v4l-cx23418-apu.fw
Drivers/Driver18/hcw18enc.rom -> v4l-cx23418-cpu.fw
Drivers/Driver18/hcw18mlC.rom -> v4l-cx23418-dig.fw

This is a video4linux driver for Conexant cx23418 based
PCI combo video recorder devices.
This is used in devices such as the Hauppauge HVR-1600
cards.
To compile this driver as a module, choose M here: the
module will be called cx18.
