Update 2: all I2C breakage is caused by i2c gates in CE6313 and TDA8290 so I just commented-out the calls in tuner drivers for now. Tuner detection in tda8290 breaks because it finds CE5039 at 0x60. Disabling CE5039 using GPIO in board_init1() and enabling it in dvb_init() allows all chips to initialize properly: [ 130.658813] saa7130/34: v4l2 driver version 0, 2, 17 loaded [ 130.662715] saa7133[0]: found at 0000:02:01.0, rev: 209, irq: 9, latency: 32, mmio: 0xf4000000 [ 130.665879] saa7133[0]: subsystem: 1461:2055, board: AverMedia AverTV Satellite Hybrid+FM A706 [card=191,autodetected] [ 130.669347] saa7133[0]: board init: gpio is 3500 [ 130.822347] saa7133[0]: i2c eeprom 00: 61 14 55 20 00 00 00 00 00 00 00 00 00 00 00 00 [ 130.825689] saa7133[0]: i2c eeprom 10: ff ff ff ff ff 20 ff ff ff ff ff ff ff ff ff ff [ 130.829008] saa7133[0]: i2c eeprom 20: 02 40 01 02 02 01 01 04 06 ff 00 57 ff ff ff ff [ 130.832317] saa7133[0]: i2c eeprom 30: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 130.835627] saa7133[0]: i2c eeprom 40: 60 a0 00 c6 96 ff 05 30 8b 05 ff 40 ff ff ff ff [ 130.838932] saa7133[0]: i2c eeprom 50: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 130.842222] saa7133[0]: i2c eeprom 60: ff 89 00 c0 ff 1c 08 19 97 89 ff ff 80 15 0a ff [ 130.845525] saa7133[0]: i2c eeprom 70: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 130.848833] saa7133[0]: i2c eeprom 80: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 130.852109] saa7133[0]: i2c eeprom 90: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 130.855351] saa7133[0]: i2c eeprom a0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 130.858565] saa7133[0]: i2c eeprom b0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 130.861736] saa7133[0]: i2c eeprom c0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 130.864894] saa7133[0]: i2c eeprom d0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 130.868021] saa7133[0]: i2c eeprom e0: 00 01 81 b0 65 07 ff ff ff ff ff ff ff ff ff ff [ 130.871133] saa7133[0]: i2c eeprom f0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 130.930349] tuner 2-004b: Tuner -1 found with type(s) Radio TV.
