Update: GPIO 9 is CE6313 SLEEP signal GPIO 23 is CE5039 SLEEP signal GPIO 25 is CE6313 RESET# signal - this one needs to be set high for CE6313 to appear on I2C bus But there is a problem with CE5039 (zl10039) - the I2C bus breaks during its initialization (SDA stuck low): Here it works (communication with CE6313): [ 921.556682] start xfer [ 921.556684] send address [ 921.556687] saa7133[0]: i2c data => 0x1c [ 921.556690] saa7133[0]: i2c stat <= BUSY [ 921.556725] saa7133[0]: i2c stat <= BUSY [ 921.556759] saa7133[0]: i2c stat <= BUSY [ 921.556794] saa7133[0]: i2c stat <= BUSY [ 921.556828] saa7133[0]: i2c stat <= DONE_WRITE [ 921.556831] saa7133[0]: i2c stat <= DONE_WRITE [ 921.556833] write bytes [ 921.556836] saa7133[0]: i2c data => 0x14 [ 921.556838] saa7133[0]: i2c stat <= BUSY [ 921.556873] saa7133[0]: i2c stat <= BUSY [ 921.556907] saa7133[0]: i2c stat <= BUSY [ 921.556942] saa7133[0]: i2c stat <= DONE_WRITE [ 921.556945] saa7133[0]: i2c stat <= DONE_WRITE [ 921.556948] saa7133[0]: i2c data => 0x40 [ 921.556950] saa7133[0]: i2c stat <= BUSY [ 921.556985] saa7133[0]: i2c stat <= BUSY [ 921.557019] saa7133[0]: i2c stat <= BUSY [ 921.557054] saa7133[0]: i2c stat <= DONE_WRITE [ 921.557057] saa7133[0]: i2c stat <= DONE_WRITE [ 921.557058] xfer done [ 921.557060] saa7133[0]: i2c attr => STOP [ 921.557064] saa7133[0]: i2c stat <= BUSY [ 921.557098] saa7133[0]: i2c stat <= DONE_STOP [ 921.557101] saa7133[0]: i2c stat <= DONE_STOP Here starts CE5039 communication: [ 921.564672] zl10039_read [ 921.564677] saa7133[0]: i2c stat <= DONE_STOP [ 921.564679] start xfer [ 921.564681] send address [ 921.564684] saa7133[0]: i2c data => 0xc0 [ 921.564686] saa7133[0]: i2c stat <= BUSY [ 921.564721] saa7133[0]: i2c stat <= BUSY [ 921.564755] saa7133[0]: i2c stat <= BUSY [ 921.564790] saa7133[0]: i2c stat <= BUSY And here it breaks: [ 921.564824] saa7133[0]: i2c stat <= ARB_LOST [ 921.564827] saa7133[0]: i2c stat <= ARB_LOST [ 921.564829] zl10039_read: i2c read error [ 921.564833] saa7133[0]: i2c stat <= ARB_LOST [ 921.564834] saa7133[0]: i2c reset [ 921.564837] saa7133[0]: i2c stat <= ARB_LOST [ 921.564839] saa7133[0]: i2c stat => ARB_LOST [ 921.564843] saa7133[0]: i2c stat <= ARB_LOST [ 921.564877] saa7133[0]: i2c stat <= IDLE [ 921.564879] saa7133[0]: i2c attr => NOP And everything is broken now (until reloading saa7134 module): [ 921.564882] start xfer [ 921.564883] send address [ 921.564886] saa7133[0]: i2c data => 0x1c [ 921.564889] saa7133[0]: i2c stat <= BUSY [ 921.564923] saa7133[0]: i2c stat <= BUSY [ 921.564958] saa7133[0]: i2c stat <= BUSY [ 921.564992] saa7133[0]: i2c stat <= BUSY [ 921.565026] saa7133[0]: i2c stat <= BUSY [ 921.565061] saa7133[0]: i2c stat <= BUSY [ 921.565095] saa7133[0]: i2c stat <= BUSY [ 921.565130] saa7133[0]: i2c stat <= BUSY [ 921.565164] saa7133[0]: i2c stat <= BUSY [ 921.565199] saa7133[0]: i2c stat <= BUSY [ 921.565233] saa7133[0]: i2c stat <= BUSY [ 921.565268] saa7133[0]: i2c stat <= BUSY [ 921.565302] saa7133[0]: i2c stat <= BUSY [ 921.565336] saa7133[0]: i2c stat <= BUSY [ 921.565371] saa7133[0]: i2c stat <= BUSY [ 921.565405] saa7133[0]: i2c stat <= BUSY [ 921.565440] mt312_read: ret == -5 [ 921.565450] saa7133[0]/dvb: dvb_init: No zl10039 found! -- Ondrej Zary -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
