• 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.

• cc51846ba   pwm: atmel-hlcdc: Fix default PWM polarity ... Browse Code »

  The PWM device exposed by the HLCDC IP is configured with an inverted
  polarity by default. Registering the PWM chip with the normal polarity
  was not a problem before commit 42e8992c58d4 ("pwm: Add core
  infrastructure to allow atomic updates") because the ->set_polarity()
  hook was called no matter the current polarity state, but this is no longer
  the case.

• 2b8b0ef35   pwm: atmel-hlcdc: add sama5d2 SoC support. ... Browse Code »

  Add sama5d2 hlcdc backlight PWM support. This chip doesn't have to deal with an
  errata, so it's a simple addition of the mfd compatible string.

• a83a6a822   pwm: atmel-hlcdc: Fix module autoload for OF platform driver ... Browse Code »

  This platform driver has a OF device ID table but the OF module alias
  information is not created so module autoloading won't work.

  This patch adds the missing MODULE_DEVICE_TABLE() for OF to export that
  information so modules have the correct aliases built-in and autoloading
  works correctly.

  sama5d4 SoC also has an errata on the HLCDC PWM. It is the same as the
  sama5d3 that is forbidding the use of div1 prescaler.

• df6922ade   pwm: atmel-hlcdc: Prevent division by zero ... Browse Code »

  The slow and system clock should never return a rate of zero, but this
  might happen if the clocks property defined in the DT is referencing the
  wrong clocks.

  Prevent any division by zero from happening by testing the clk_freq
  value before calling do_div().

  at91sam9x5 has an errata forbidding the use of slow clk as a clk source and
  sama5d3 SoCs has another errata forbidding the use of div1 prescaler.

  Take both of these erratas into account.

• 2b4984bef   pwm: add support for atmel-hlcdc-pwm device ... Browse Code »

  The HLCDC IP available in some Atmel SoCs (i.e. at91sam9x5, at91sam9n12
  or sama5d3 families for instance) provides a PWM device.

  This driver add support for a PWM chip exposing a single PWM device (which
  will most likely be used to drive a backlight device).
