TBS6985 no frontend on adapter0 and adapter1 #146

Open wociscz opened 7 years ago

wociscz commented 7 years ago

Hi, i have similar issue like https://github.com/ljalves/linux_media/issues/107

Modules built ok (followed local wiki howto), rebooted and there are frontends only at adapter2&3 Actual setup: ubuntu 16.04, kernel 4.4.0-36 (ubuntu), mini-itx ipx7-ion (atom 330 with nvidia chips all around) Tried kernel 4.6 - same behaviour, 4.8 - modules wont build.

Didn't find solution (clean install not tried) One note - before tbs6985, i have tbs6980 in same machine (works fine both tuners)

Adapter2&3 works fine, but 4 adapters will be better :-)

From kern.log i2c errors:

i think need disable using I2C_MUX adapter inside tas2101 driver. 03a5a706b9b938c22e54432d3b530d653a390149

Disabled as in the https://github.com/ljalves/linux_media/commit/03a5a706b9b938c22e54432d3b530d653a390149 but same. Kern log after modprobing is "shorter" :-) but same situation -frontends missing on adapters 0&1

Is there any known solution to this?

Thanks in advance!
