TBS 8920 still fails to initialize - cx24116_readreg error

TBS 8920 still fails to initialize - cx24116_readreg error

[Mark Zimmerman]

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?

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.

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.

This was successful.  So that there is no miscommunication, let me
specify exactly what I tested:

I started with

hg clone http://mercurial.intuxication.org/hg/s2-liplianin/rev/b1ca288a0600

and then changed cx88-dvb.c as follows:

which added this to dmesg:

I think that this is all that I can test without a satellite dish;
please let me know if there is anything else I can do.

Thanks for looking at this.

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