• 8c0216f37   pwm: Remove .can_sleep from struct pwm_chip ... Browse Code »

  All PWM devices have been marked as "might sleep" since v4.5, there is
  no longer a need to differentiate on a per-chip basis.

• fe0aea797   pwm: kona: Modify settings application sequence ... Browse Code »

  Update the driver so that settings are applied in accordance with the
  most recent version of the hardware spec. The revised sequence clears
  the trigger bit, waits 400ns, writes settings, sets the trigger bit,
  and waits another 400ns. This corrects an issue where occasionally a
  requested change was not properly reflected in the PWM output.

• 15da7b500   pwm: Make use of pwm_get_xxx() helpers where appropriate ... Browse Code »

  Use the pwm_get_xxx() helpers instead of directly accessing the fields
  in struct pwm_device. This will allow us to smoothly move to the atomic
  update approach.

• 5c31252c4   pwm: Add the pwm_is_enabled() helper ... Browse Code »

  Some PWM drivers are testing the PWMF_ENABLED flag. Create a helper
  function to hide the logic behind enabled test. This will allow us to
  smoothly move from the current approach to an atomic PWM update
  approach.

• e23db65f3   pwm: bcm-kona: Don't set polarity in probe ... Browse Code »

  Omit setting the polarity to normal during probe and instead use the new
  pwmchip_add_with_polarity() function to register a PWM chip with inverse
  polarity by default for all channels to reflect the hardware default.
