I just noticed a problem in v4.16 kernels with twl4030 audio and vibra driver no longer working.
Tracing it back shows that it already did appear in v4.16-rc1 and wasn't fixed up to v4.16.0.
Kernel v4.15.9 (the latest one where I have a binary) works.
The symptoms are:
[ 1.557342] twl4030-audio 48070000.i2c:twl at 48:audio: Invalid audio_mclk
[ 1.564788] twl4030-audio: probe of 48070000.i2c:twl at 48:audio failed with error -22
[ 1.839141] TWL4030: HFCLK is not configured
Those are not visible in v4.15.9. And I am not aware of any changes to the gta04 device tree.
Do you know about this issue and a fix, before I start to bisect?
BR and thanks,
