[linux-dvb] Remote on Lifeview Trio: anyone got it working?

[linux-dvb] Remote on Lifeview Trio: anyone got it working?

[Nico Sabbi]

Hi,
did anyone get the remote controller on the Trio working?
I found a patch from which it seems that it talks via i2c either
at 0x0b or at 0x0e address and someone reported success,
but it seems that no patch was applied to linuxtv's HG repository.

Can anyone who has it working post the correct patch(-es), please?

Thanks,
	Nico

you find the patch from Eddi based on the Henry Wong MSI TV@nywhere
patch here.

http://tux.dpeddi.com/lr319sta

You might have to apply it manually, since quite old.
If so, please post an updated patch after that for others.
It is known to work.

Doing the probing of the IR chip in ir-kbd-i2c to make it responsive is
the main reason for not have been included, since it is expected not to
be accepted at mainline. 

According to Eddi and Peter on the video4linux-list on May 28 2007, the
driver has a flaw in implementing i2c remotes card specific.
Dwaine Garden with the same problem on the Kworld ATSC110 also confirmed
that it is not possible to initialize the similar behaving KS chips from
saa7134-cards.c currently. His patch version is also only off tree
available.

Sampling from gpio IRQ, what we do on recent Asus PC39 remotes, is also
not implemented yet for i2c remotes and the lack is visible in
saa7134-core.c.

Cheers,
Hermann

Hi Hermann,

With regards this patch, the i2c stuff has changed in ir-kbd-i2c.c.
I have previously successfully modified Henry's patch for various i2c 
remotes.

However it no longer works, because of this change where the probing was 
done:

Part of Henry's patch:
<snip>
c.adapter = adap;
for (i = 0; -1 != probe[i]; i++) {
c.addr = probe[i];
+
+ if (c.adapter->id == I2C_HW_SAA7134 && probe[i] == 0x0b) {
+ /* enable ir receiver */
+ buf = 0;
+ if (1 != i2c_master_send(&c,&buf,1))
+ dprintk(1,"Unable to enable ir receiver.\n");
+ }
rc = i2c_master_recv(&c,&buf,0);
dprintk(1,"probe 0x%02x @ %s: %s\n",
probe[i], adap->name,
<snip>

The new i2c setup:
<snip>
for (i = 0; -1 != probe[i]; i++) {
msg.addr = probe[i];
rc = i2c_transfer(adap, &msg, 1);
dprintk(1,"probe 0x%02x @ %s: %s\n",
probe[i], adap->name,
(1 == rc) ? "yes" : "no");
if (1 == rc) {
ir_attach(adap, probe[i], 0, 0);
break;
}
}
<snip>
I have a few saa7134 cards with i2c remotes - all of these remotes are 
completely dead.

Does anybody have a suggestion how to make this work, now?

Regards,
Timf
