Hello Linus,

The following changes since commit 517fb4d77c44c7519ae6937329c496894461f416:

  pwm: Assume a disabled PWM to emit a constant inactive output (2024-11-07 12:03:39 +0100)

----------------------------------------------------------------
pwm: Changes for v6.13-rc1

This pull request prominently contains a new abstraction for PWM
waveforms that is more expressive that the legacy one. Compared to the
old abstraction it contains a duty_offset member instead of polarity.
This new abstraction is already used in an ADC driver merged into the
iio tree. So I expect you will get a part of this tree also via the iio
pull request for 6.13-rc1 (tag pwm/duty_offset-for-6.13-rc1).

Otherwise it's the usual collection of fixes, cleanups and dt doc
updates.

This time around thanks go to Andy Shevchenko, Clark Wang, Conor Dooley,
David Lechner, Dimitri Fedrau, Frank Li, Jun Li, Kelvin Zhang, Krzysztof
Kozlowski, Nuno Sa, Shen Lichuan and Trevor Gamblin for code
contributions, testing and review.

----------------------------------------------------------------

The new API requires changes to the lowlevel drivers. For now there are
two drivers that are converted to the new API (axi-pwmgen and stm32).
Converted drivers continue to work with the old API. Drivers not yet
converted only work with the older API.

Please pull these changes for 6.13-rc1.

Thanks
Uwe
