Now to find GPIO's for LNB power control and ... watch TV :)
Yep. No succesful tuning at the moment. There might also be an issue
with the reset signal and writing to GPIOCTR, as the module at the
moment loads succesfully only once.
As far as I can make out, the LNB power control is probably GPIO 16
and 17, not sure which is which, and how they work.
GPIO15 is wired to tuner #reset
New patch to test
I think the LNB voltage may be a little to high on my card, 14.5V and
20V. I would be a little more happy if they were 14 and 19, 13 and 18
would be perfect.
Anyways, as Igor pointet out, I don't have any signal from the LNB,
checked with another tuner card. It's a quad LNB, and the other outputs
are fine. Maybe it's' toasted from to high supply voltage! I little word
of warning then.
Anyways, here's my tweaked driver.
Here is reworked patch for clear GPIO's handling.
It allows to support I2C on GPIO's and per board LNB control through
GPIO's. Also incuded support for Hendrik's card.
I think it is clear how to change and test GPIO's for LNB and other stuff
now.
To Hendrik:
Not shure, but there is maybe GPIO for raise/down LNB voltage a little
(~1v). It is used for long coaxial lines to compensate voltage
dropping.

Hi Igor,
I have a brandless DVB-S tv tuner card also, with a dm1105n chip. I was
getting the "DM1105: could not attach frontend 195d:1105" message with
the latest kernel also, but I applied this patch to the dm1105 module
and now the card's being recognised (though is still listed as an
ethernet controller with lspci)
My dmesg output is:
dm1105 0000:01:05.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
DVB: registering new adapter (dm1105)
dm1105 0000:01:05.0: MAC 00:00:00:00:00:00
DVB: registering adapter 0 frontend 0 (SL SI21XX DVB-S)...
Registered IR keymap rc-dm1105-nec
input: DVB on-card IR receiver as
/devices/pci0000:00/0000:00:1e.0/0000:01:05.0/rc/rc0/input6
rc0: DVB on-card IR receiver as
/devices/pci0000:00/0000:00:1e.0/0000:01:05.0/rc/rc0
The card is one of these:

Scanning doesn't appear to give me any results. Should this be working?
Anything I can do to test the card out for you?
Cheers,
Matt.
Hi Matt,
Is there any label on tuner can?
Have you a close look picture of PCB ?
Cheers,
Igor.
Hi Igor,
The label on the tuner can is SP1514LHb S1009, so I'm guessing this is a
near-identical card to the one that Paul was asking you about in January
of last year, e.g:
1: DVB-S
5: 16cc
1: Unsure, but it has an LNB in and an LNB out, so I guess it does have
loop through?
4: Si2109
L: Si labs
H: Horizontal
b: Lead free
Here are two images I took of the card:
A view of the entire board:

And here is a closer view of the board between the tuner and the dm1105n
chip.

With your patch and the card=4 parameter the card is recognised, and the
dvb device created. Scanning will run (I'm attempting to locate channels
on Optus D1, which I can successfully scan using a set top box, so the
dish is correctly aligned), but the card reports tuning failed on all of
the Optus D1 frequencies that I attempt. I also tried running w_scan but
had no success.
Cheers,
Matt.
