Subject: [PATCH v4 0/4] StarFive's Pulse Width Modulation driver support
Date: Thu, 1 Jun 2023 16:51:50 +0800 [thread overview]
Message-ID: <20230601085154.36938-1-william.qiu@starfivetech.com> (raw)
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 v2->v3:
- Rebased to v6.4rc3.
- 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 v6.4rc3.
