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@48:audio: Invalid audio_mclk [ 1.564788] twl4030-audio: probe of 48070000.i2c:twl@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, Nikolaus
