Hello Jonathan,

The following changes since commit d242feaf81d63b25d8c1fb1a68738dc33966a376:

  pwm: stm32: Fix a typo (2024-09-16 15:24:59 +0200)

  pwm: stm32: Fix error checking for a regmap_read() call (2024-10-04 19:03:12 +0200)

The base is contained in v6.12-rc1. The head will be part of my pull
request to Linus for the next merge window. If you pull that into your
tree, you can apply Trevor's series for the ad7625.

The tag contains two fixes on top of the original series that cure a few
warnings. The commits were in next a few days now without further
reported fall-outs, so it should be reasonably safe for you to pull it
into your tree.

pwm: Support for duty_offset

Support a new abstraction for pwm configuration that allows to specify
the time between start of period and the raising edge of the signal
("duty offset").

This is used in a patch series by Trevor Gamblin for triggering an ADC
conversion and afterwards read out the result. See
https://lore.kernel.org/linux-iio/[e-mail]/
for more details.
