This PMIC is commonly used on boards with an SM6125 SoC and looks very
similar in layout to the PM6150.

Downstream declares more nodes to be available, but these have been
omitted from this patch: the pwm/lpg block is unused on my reference
device making it impossible to test/validate, and the spmi-clkdiv does
not have a single device-tree binding using this driver yet, hence
inclusion is better postponed until ie. audio which uses these clocks is
brought up.

I can respin the series with the suggested changes (and the iio patch
removed as that has now been applied), but note that all other PMIC dtsi
files as of -next today still carry the "wrong" adc-tm or gpios node
names.  Are there plans to patch those up too (if not already in a
series that I missed)?

My comment was here not correct. The schema indeed expects this to be
adc-tm. I did not plan to change it, so let's keep adc-tm also here.

Both are allowed by schema, but convention in all other cases is "gpio",
so let's change it. I'll send a patch for other files.

Best regards,
