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. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEP4GsaTp6HlmJrf7Tj4D7WH0S/k4FAmc7DoAACgkQj4D7WH0S /k5tEgf/QJY8mAPPZR45dDo+GdUnZAaV85sseOezeApjB6kMYXKsKWoDC0uQ9m40 t7zkR8rXCk84rYSg4fGpcWL12v03n8cXmABkJUsqkUkLCcU/pifKzxanC25IWMH1 DGCW8tev4/NSe2ud9kLmFR/p85aioIW47Az3QH096Wv+Y5ij3v5e8PHBIaSiWHlb gfQI1XWerHSbAZexF132zGZOD/TBWb6djAQKACh5KWBPWB54zK3n3ngxoOCSMKSh Li8nfVyy32mPurLfTqaTaAHg7uGrcCGOVhqnXSQiuUayMlV/T7FX/uwfF/X/YKFm iqIPoYeUhLHmHJkHLACtPzUajkTJbg== =3d9l -----END PGP SIGNATURE----- Merge tag 'pwm/for-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux Pull pwm updates from Uwe Kleine-König: "This 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. 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. Otherwise it's the usual collection of fixes, cleanups and dt doc updates.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
