Hello,
I have a LDO1 in dmesg now with the patch from yesterday sent to the
lkml from Mark Brown (thank you, Mark).
("[PATCH] regulator: core: Handle full constraints systems when
resolving supplies").
here is the feedback after applying Mark's patch above.
I got NO loop in arizona_dev_init() anymore -
so far so good. This patch does work at least for me.
The actual dmesg shows me that LDO1 seems to be set right.

the only open issue seems the unkown device id, and this could be
coming from the (wrong) spi initialization I think.
As I have changed to not use the spi_get_device_id() function., and
there still seems to be missing some code (the read back of the device
id fails as another developer mentioned)
The first line "sst-acpi 80860F28:00: No matching ASoC machine driver found"
should be fine with the last patch holding on the local stash.
Also I have some new questions regarding to the firmware I have
to load here.
Currently I have the fw_sst_0f28.bin-48kHz_i2s_master which seems not
correct (i2c)
Do not know yet if I can or should take the default one ( which should
be in this case fw_sst_0f28.bin)
Does somebody of for intel_sst_acpi and the WM5102 codec if a new or
specific firmware must be used to
let this codec work at all.
cheers
chris
