Hi all,
After using Mauro's patch, I try to set the gpio pin in function
"saa7134_xc2028_callback".
Now, I can watch analog TV.
The GPIO pin 21 seems the reset pin for tuner.
The mt352 demod is still no response....
===========================================================
static int saa7134_xc2028_callback(struct saa7134_dev *dev,
int command, int arg)
{
switch (command) {
case XC2028_TUNER_RESET:
saa_andorl(SAA7134_GPIO_GPMODE0 >> 2, 0x06e20000, 0x06e20000);
saa_andorl(SAA7134_GPIO_GPSTATUS0 >> 2, 0x06a20000, 0x06a20000);
saa_andorl(SAA7133_ANALOG_IO_SELECT >> 2, 0x02, 0x02);
saa_andorl(SAA7134_ANALOG_IN_CTRL1 >> 2, 0x81, 0x81);
saa_andorl(SAA7134_AUDIO_CLOCK0 >> 2, 0x03187de7, 0x03187de7);
saa_andorl(SAA7134_AUDIO_PLL_CTRL >> 2, 0x03, 0x03);
saa_andorl(SAA7134_AUDIO_CLOCKS_PER_FIELD0 >> 2,
0x0001e000, 0x0001e000);
#if 1
saa7134_set_gpio(dev, 21, 0);
msleep(20);
saa7134_set_gpio(dev, 21, 1);
#endif
return 0;
}
return -EINVAL;
}
