v2: Use the existing config callback with duty_ns and period_ns(Thierry)
v3: Correct the subject line (Lee jones)
v4: Address comment by Thierry & Paul
- Commit message update and fixes for few syntax errors
- Add PWM_CRC in Kconfig and Makefile sorted alphabetically
- Use the PWM_BASE_CLK as 6000000 for better code readability
- Remove the redundant rule of three while calculating pwm level
- Use the platform_device in pwm_chip
- Use builin_platform_driver
v5: Address comments by Varka
- Make the bit definition using BIT macro
- reorder probe and remove code to directly return from pwmchip_add/remove
