• 0b60111aa   power: regulator: pwm: support pwm polarity setting ... Browse Code »

  The latest kernel PWM drivers enable the polarity settings. When system
  run from U-Boot to kerenl, if there are differences in polarity set or
  duty cycle, the PMW will re-init:
  close -> set polarity and duty cycle -> enable the PWM.
  The power supply controled by pwm regulator may have voltage shaking,
  which lead to the system not stable.
