Hello,
I don't get a rhyme out of it, what should have caused on 2.6.15-rc3 and
rc5 that port2=0 should have been set? We never did this by intention
and still don't do it, AFAIK.
That the error in the attempted fix causes the trouble now is obvious,
but it should currently not be needed at all. But since as far as I can
see it also should not create trouble in digital mode, the fix of the
fix is attached that it does what the plan was.
There is one more thing to investigate for the 300i. The digital tuning
is reportedly broken since about after 20050627.
A little bit hidden in mt20xx it was found now that the change to
digital tuner mode fails and digital works if the digital if2 is forced
with if (1) { instead. (the needed warm-up time was often reported)
static void mt2050_set_tv_freq(struct i2c_client *c, unsigned int freq)
{
struct tuner *t = i2c_get_clientdata(c);
unsigned int if2;
if (t->std & V4L2_STD_525_60) {
// NTSC
if2 = 45750*1000;
} else {
// PAL
if2 = 38900*1000;
}
if (V4L2_TUNER_DIGITAL_TV == t->mode) {
// DVB (pinnacle 300i)
if2 = 36150*1000;
}
mt2050_set_if_freq(c, freq*62500, if2);
mt2050_set_antenna(c, tv_antenna);
}
Does somebody know if it most likely needs more than only to setup
case SAA7134_BOARD_PINNACLE_300I_DVBT_PAL:
{
struct tuner_setup tun_setup;
tun_setup.mode_mask = T_ANALOG_TV | T_DIGITAL_TV;
tun_setup.type = dev->tuner_type;
tun_setup.addr = ADDR_UNSET;
saa7134_i2c_call_clients (dev, TUNER_SET_TYPE_ADDR,&tun_setup);
}
break;
in saa7134-cards.c saa7134_board_init2, or would this be already worth a
try?
Cheers,
Hermann
- Fix an error in the previously attempted fixes of saa7134 Pinnacle
cards with microtune mt2050 and tda9886 to keep the tuner responsive.
