Hi all
I'm trying to run the digital part of the card MyGica X8507 and I need
help on some issues.
Need data sheet of IC MB86A20S and no where to get it. Fujitsu People of
Germany told me: "This is a very old product and not supported any
more". Does anyone know where to get it?
I never found any public datasheet for this device.
Congratulations for driver you have made

In the bus 0 is demodulator mb86a20s 0x20 (0x10) and in the bus 1 the
tuner (xc5000). I understand that would have to be cancel the mb86a20s
i2c_gate_ctrl similarly as in the IC zl10353. If this is possible, is
not yet implemented in the controller of mb86a20s. The IC cx23885 is
always who controls the tuner i2c bus.
Well, if you don't add an i2c_gate_ctrl() callback, the mb86a20s won't
be calling it. So, IMO, the cleanest approach would simply to do:
fe->dvb.frontend->ops.i2c_gate_ctrl = NULL;
after tuner attach, if the tuner or the bridge driver implements an i2c gate.
I don't think xc5000 does. The mb86a20s also has its own i2c gate and gpio
ports that might be used to control an external gate, but support for it is
currently not implemented, as no known device uses it.
If in this way, it does not work:
case CX23885_BOARD_MYGICA_X8507:
i2c_bus = &dev->i2c_bus[0];
i2c_bus2 = &dev->i2c_bus[1];
fe0->dvb.frontend = dvb_attach(mb86a20s_attach,
&mygica_x8507_mb86a20s_config,
&i2c_bus->i2c_adap);
if (fe0->dvb.frontend != NULL) {
dvb_attach(xc5000_attach,
fe0->dvb.frontend,
&i2c_bus2->i2c_adap,
&mygica_x8507_xc5000_config);
fe0->dvb.frontend->ops.i2c_gate_ctrl = NULL;
fe0->dvb.frontend->ops.tuner_ops.init(fe0->dvb.frontend);
I get:
...dmesg
...
[ 964.105688] mb86a20s: mb86a20s_read_status: val = 2, status = 0x01
[ 964.105696] mb86a20s: mb86a20s_set_frontend:
[ 964.105700] mb86a20s: mb86a20s_set_frontend: Calling tuner set parameters
So, all you need is to attach both mb86a20s and xc5000 on it, and set the
proper GPIO's.
I think I'm doing well
case CX23885_BOARD_MYGICA_X8506:
case CX23885_BOARD_MYGICA_X8507:
case CX23885_BOARD_MAGICPRO_PROHDTVE2:
/* Select Digital TV */
cx23885_gpio_set(dev, GPIO_0);
break;
X8508 and X8507 is the same card, just change the digital part.
The driver for windows says:
X8507 means X8502

It will call fe->ops.tuner_ops.set_params(fe) inside the set_frontend() fops
logic, in order to tune the device, but this is the same thing as
zl10353_set_parameters does.
I expected something like this:
From zl10353, page 12:
3.1.2
Tuner
The ZL10353 has a General Purpose Port that can be configured to provide
a secondary 2-wire bus. See register
GPP_CTL address 0x8C.
Master control mode is selected by setting register SCAN_CTL (0x62) [b3]
= 1.
From V4L driver, zl10353.c
static int zl10353_i2c_gate_ctrl(struct dvb_frontend* fe, int enable)
{
struct zl10353_state *state = fe->demodulator_priv;
u8 val = 0x0a;
if (state->config.disable_i2c_gate_ctrl) {
/* No tuner attached to the internal I2C bus */
/* If set enable I2C bridge, the main I2C bus stopped hardly */
return 0;
}
if (enable)
val |= 0x10;
return zl10353_single_write(fe, 0x62, val);
Maybe I'm misunderstanding the code.
When I do notknow the pins of integrated circuits I can not measure the
state of the GPIO.
Please, could you tell me if I'm reasoning correctly?
Using RegSpy I see the bus 0 alternately accesses to addresses 0x20 and
0x66under Windows 7. In Windows XP only accessed to 0x20 and when the pc
starts to 0xa0.
Bus 2 (internal) always accesse to 0x88
The bus 0 and 2 (internal) access to the address 0x66 (according
modprobe cx23885 i2c_scan), What's there?
Maybe a remote controller? Do you have a high-resolution picture of the
board?
Do not know if I can be the remote, but only does so under windows7 bus
0 accesses the address 0x66.
Under Windows XP does not access the bus 0 to address 0x66.
I have no photos in high resolution, but I can get a camera if it helps
you to help me.
Here are photos in low resolution:
