TBS 8920 still fails to initialize - cx24116_readreg error

Greetings:

Using current current v4l-dvb drivers, I get the following in the dmesg:

cx88[1]/2: subsystem: 8920:8888, board: TBS 8920 DVB-S/S2 [card=72] cx88[1]/2: cx2388x based DVB/ATSC card cx8802_alloc_frontends() allocating 1 frontend(s)
cx24116_readreg: reg=0xff (error=-6)
cx24116_readreg: reg=0xfe (error=-6)
Invalid probe, probably not a CX24116 device
cx88[1]/2: frontend initialization failed
cx88[1]/2: dvb_register failed (err = -22)
cx88[1]/2: cx8802 probe failed, err = -22

Does this mean that one of the chips on this card is different than expected? How can I gather useful information about this?

Hi
You can try:
http://www.tbsdtv.com/download/tbs6920_8920_v23_linux_x86_x64.rar

This code did not compile as-is, but after I commented out some things in drivers I do not need, I managed to build something. The TBS card now seems to be initialized, but it also broke support for my DViCO FusionHDTV7 Dual Express card, which also uses a cx23885.

I am going to move this card to another machine that does not have any other capture cards and repeat the process. This should make it easier to know what the TBS card/driver is doing.

I am assuming that you are interested in using me to gather information to update the v4l-dvb drivers so that this card can be supported properly. Is this correct? Please let me know what I can do to assist.

I've changed tbs 8920 initialization in http://mercurial.intuxication.org/hg/s2-liplianin.
I ask you to try it.
If it works, then I will commit it to linuxv.
Also pay attention to remote.

Unfortunately, there appears to be no change:

Just for reference, here is how it looks when using the drivers compiled from the source in tbs6920_8920_v23_linux_x86_x64.rar:

Also, here are the diffs of cx88-dvb.c between your version and the one from the manufacturer. I wonder if the magic number writes at line 1142 could be what makes it work. I can try adding them to your source if you think it is advisable.

It is advisable to try.
I forgot about voltage control. It must preserve that "magic" number.

Please try attached patch against recent v4l-dvb.
It does matter to set explicitly gpio0 value in cx88_board structure for TBS 8920 card.
