MADC conversion (tps65930)

I set gpbr1 to 0x90, and then read out the value of 0x1f

ret = twl_i2c_read_u8(TWL_MODULE_AUDIO_VOICE, &tmp, 0x0c);

tmp |=0x90;

ret = twl_i2c_write_u8(TWL_MODULE_AUDIO_VOICE, tmp, 0x0c);

ret = twl_i2c_read_u8(TWL_MODULE_AUDIO_VOICE, &tmp, 0x0c);

The MADC can't start conversion .

thanks
