I think the Windows guys specify very little through ACPI and hard-code most of it into the driver, so you are probably going to need to find a way to define some pdata for the CODEC to get things going here. Also not finding DCVDD is a bit odd make sure you have the arizona-ldo1 driver built into your system. > [ 6.194727] sst-acpi 80860F28:00: No matching ASoC machine driver found > > Note : most of the messages here are by local dev_err() added into > some functions used to see whats going > on there... > > It seems that I have to patch arizona_core again: the function > arizona_dev_init() to, so it will find and use the correct device > ID... > So going on and will report soon again > > That all but not trivial... > > > cheers > Christian H.
