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.
