Hi,

This patchset adds initial rudimentary support for the StarFive
Pulse Width Modulation controller driver. And this driver will
be used in StarFive's VisionFive 2 board.The first patch add
Documentations for the device and Patch 2 adds device probe for
the module.

Changes v3->v4:
- Rebased to v6.5rc7.
- Sorted the header files in alphabetic order.
- Changed iowrite32() to writel().
- Added a way to turn off.
- Moified polarity inversion implementation.
- Added 7100 support.
- Added dts patches.
- Used the various helpers in linux/math.h.
- Corrected formatting problems.
- Renamed dtbinding  to 'starfive,jh7100-pwm.yaml'.
- Dropped the redundant code.

Changes v2->v3:
- Fixed some formatting issues.

Changes v1->v2:
- Renamed the dt-binding 'pwm-starfive.yaml' to 'starfive,jh7110-pwm.yaml'.
- Dropped the compatible's Items.
- Dropped the unuse defines.
- Modified the code to follow the Linux coding style.
- Changed return value to dev_err_probe.
- Dropped the unnecessary local variable.

The patch series is based on v6.5rc7.

Out of curiosity, why is this series still an RFC?

There was no comments received in v4. So William resend it and
request for comments.

The question was: why he requests for comments?

RFC means *it should not be merged, it is not ready*.

Oh, it was misunderstood by William and me.
So this series is not a RFC.
