[PATCH v2 0/2] riscv: pwm: sophgo: add pwm support for CV1800

[Jingbao Qiu]

The Sophgo CV1800 chip provides a set of four independent
PWM channel outputs.
This series adds PWM controller support for Sophgo cv1800.

Changes since v1:
- drop full stop from subject
- re-order maintainers and description
- pass checkpatch.pl --strict
- fix naming errors
- add "Limitations" section
- use a driver specific prefix for all defines
- using bool instead u32 in cv1800_pwm_enable
- check and set state->polarity
- use mul_u64_u64_div_u64
- use clk_rate_exclusive_get(), balance with clk_rate_exclusive_put()
- using macro definitions instead of shift operations
- remove shift operation on 0
- use priv replace cv_pwm 
- hardcode npwm
- set atomic to true
- remove MODULE_ALIAS
