The first name is taken from command name that's why shouldn't be listed in help. And commands shouldn't be listed with <> which means value but value itself is command name. Also add description for commands to make it clear what it does.
Before pwm pwm <invert> <pwm_dev_num> <channel> <polarity> pwm <config> <pwm_dev_num> <channel> <period_ns> <duty_ns> ...
After: pwm invert <pwm_dev_num> <channel> <polarity> - invert polarity pwm config <pwm_dev_num> <channel> <period_ns> <duty_ns> - config PWM pwm enable <pwm_dev_num> <channel> - enable PWM output pwm disable <pwm_dev_num> <channel> - disable PWM output
