Thanks for the patches. ¿Is your lastest unified diff on your page
(a700_full_20080412.diff) equivalent to these patches or must they be
applied separately?

I'll try to some tests tonight, if you have made some progress. By the way,
¿could you tell me if it's better to use use_frontend=0 or 1 for saa7134-dvb
module? I think that this changes the driver used for frontend, but I'm not
sure.

Regards,
  Eduard

Another 2 weeks later. These patches already have been applied at hg level. So 
now the new remaining full patch (a700_full_20080427.diff) is to be applied 
on top.

It contains a zl10036 driver and the changes to the glue code in saa7134-dvb.
zl10036 works most of the time here, but I am not fully happy with its current 
design.

Open issues:
* Should set_params routine be kept spiltted as it is?
* Is bandwidth handling sane?
Now calc the needed bw by symbolrate and add 3MHz.
Datasheet suggests to start at max setting and decrease as possible after the 
lock is established (using freq. offset info from demod).
* The used gain values are found by try and error and do not work for all 
transponders here.
The most difficult transponder here was RTL - and that now works for me with 
exactly these gain settings (rfg=0, ba=1, bg=1).

use_frontend is intended to be used for choosing between dvb-s and dvb-t or 
similar if the frontend offers both exclusively. I abused this parameter to 
choose between the two driver for zl10313 demod. This is no longer used, so 
forget about this parameter.

Re: [linux-dvb] a700 support (was: [patch 5/5] mt312: add attach-time setting to invert lnb-voltage (Matthias Schwarzott))

[Eduard Huguet]

[-- Attachment #1.1: Type: text/plain, Size: 5164 bytes --]

Thank you very much, Matthias. I was going to try the patch right now,
however I'm finding that it doesn't apply clean to the current HG tree. This
is what I'm getting:

patching file linux/drivers/media/dvb/frontends/Kconfig
Hunk #1 FAILED at 368.
1 out of 1 hunk FAILED -- saving rejects to file

Hunk #3 succeeded at 5716 (offset 42 lines).
patching file linux/drivers/media/video/saa7134/saa7134-dvb.c

I've tried to manually patch Kconfig by adding the rejected lines, but I
suppose there must something I'm doing wrong: apparently it compiles fine,
but saa7134-dvb is not loaded and the frontend is not being created for the
card (although the card is detected and the video0 device for analog is
there).

I'll apreciate any hints you could give me, I'm impatient to test this.
Plus, I'm seing lately some cross posted messages regarding the chips on
this cards, so maybe there's some hope for it :D

Best regards,
  Eduard

This reject is caused by the massive movement of the hybrid tuner drivers to 
another directory.
I solved the reject, and re-uploaded the patch.
Here it does still work.

Well, still no luck. I'm unable to discover any channel from Astra 19.2
neither from dvbscan nor Kaffeine. For the sake of any possible diagnostics,
here you have the dmesg output for the "modprobe saa7134 i2c_scan=1"

I have also "debug=1" for mt312 module, as you might see. I don't know if
this can be also helpful, but this is the dmesg output when scanning
channels from within Kaffeine:

The output was indeed longer, I've shortened it a bit because it's the same
