• 5bd0b9011   pwm: clps711x: Use 64-bit division macro ... Browse Code »

  Since the PWM framework is switching struct pwm_args.period's datatype
  to u64, prepare for this transition by using DIV64_U64_ROUND_CLOSEST to
  handle a 64-bit divisor.

  Commit e39c0df1be5a ("pwm: Introduce the pwm_args concept") has
  changed the variable for the period for clps711x-pwm driver, so now
  pwm_get/set_period() works with pwm->state.period variable instead
  of pwm->args.period.
  This patch changes the period variable in other places where it is used.

• ba60ae1dc   pwm: clps711x: Changing the compatibility string to match with the smallest supported chip ... Browse Code »

  This patch changes the compatibility string to match with the smallest
  supported chip (EP7209). Since the DT-support for this CPU is not yet
  announced, this change is safe.

• e39c0df1b   pwm: Introduce the pwm_args concept ... Browse Code »

  Currently the PWM core mixes the current PWM state with the per-platform
  reference config (specified through the PWM lookup table, DT definition
  or directly hardcoded in PWM drivers).

  Create a struct pwm_args to store this reference configuration, so that
  PWM users can differentiate between the current and reference
  configurations.

  Patch all places where pwm->args should be initialized. We keep the
  pwm_set_polarity/period() calls until all PWM users are patched to use
  pwm_args instead of pwm_get_period/polarity().

  A platform_driver does not need to set an owner, it will be populated by the
  driver core.

  Add a new driver for the ARM CLPS711X Pulse Width Modulator (PWM) interface.
  This CPU contain two 4-bit PWM outputs with constant period, based on CPU
  PLL frequency. PWM polarity is determined by hardware by power on reset.
