Re: DTV2000 H Plus issues

["istvan_v@mailbox.hu" <istvan_v@mailbox.hu>]

I have an updated version now, with these changes:
  - the firmware file name can be specified with the "firmware_name"
    module parameter; it defaults to "xc4000.fw"
  - there is another new module parameter ("audio_std") for configuring
    the audio standard (NICAM, A2, etc.), and switching FM radio to
    using input 1 (i.e. cable TV instead of FM antenna). This is an
    integer value which can be the sum of:
      1: use NICAM/B or A2/B instead of NICAM/A or A2/A
      2: use A2 instead of NICAM or BTSC
      4: use SECAM K3 instead of K1
      8: in SECAM D/K mode, set the IF frequency and audio mode as for
         SECAM-L (this hack fixed the one SECAM channel I can receive)
     16: use FM radio input 1 instead of input 2
     32: mono TV audio (does not seem to work, so it is useless)
  - "struct xc4000_config" has a new member ("card_type") for specifying
    the card type
  - some code changes to allow for loading the new firmware files below
In addition to analog TV and FM radio, I have tested the IR as well, and
it apparently works. DVB-T is still untested, however.

There are two separate patches for v4l-dvb revision 28f5eca12bb0: the
first one adds the XC4000 driver, while the second one adds support for
the Leadtek WinFast DTV2000H Plus card in the CX88 driver.

These new firmware files are more complete than the previous ones, but
are not compatible with the original driver. Both version 1.2 and 1.4
are available:

http://www.sharemation.com/IstvanV/v4l/xc4000-1.2.fw
http://www.sharemation.com/IstvanV/v4l/xc4000-1.4.fw

Note that the 1.4 firmware could have two different versions of DTV6,
which only differ in the audio mode register: 0x8002 (as in v1.2) vs.
0x8003. However, the above file includes only the latter one.

The following simple utility was used for creating the firmware files.
It can extract the firmware data from a Windows driver file (e.g.
hcw85bda.sys from Hauppauge, wfeaglxt.sys from Leadtek, etc.;
dvb7700all.sys from Pinnacle will not work, however), and supports both
v1.2 and v1.4 firmware. The tables at the beginning of the code are not
necessarily fully correct, though, and may need some fixing.
