[GitBox <gi...@apache.org>]

daniel-p-carvalho opened a new pull request #4284:
URL: https://github.com/apache/incubator-nuttx/pull/4284


   ## Summary
   
   Fix a problem that happens when we try to stop and restart a PWM signal. The problem seems to be related with pwm_stop() function. This function set PWM frequency to zero and reset TIMER peripheral to it's default state. From my understanding the pwm_start() funtion is not able to reconfigure the timer to a functional state. So I change this function to disable the timer and timer outputs.
   
   ## Impact
   
   This change may break stm32_pwm driver.
   
   ## Testing
   
   Tested on:
   
    - nucleo-g431:pwm
    - stm32f334-disco:powerled
