The MC33XS2410 is a four channel high-side switch. Featuring advanced
monitoring and control function, the device is operational from 3.0 V to
60 V. The device is controlled by SPI port for configuration.

Changes in V2:
  - fix title in devicetree binding
  - fix commit message in devicetree binding patch
  - remove external clock from pwms and create clocks property
  - switch to unevaluatedProperties: false
  - add missing properties for complete example:
    - pwm-names
    - pwms
    - interrupts
    - clocks

Changes in V3:
  - Add description of the general behaviour of the device (limitations)
  - Drop unused defines
  - Add ranges comments for defines with parameters
  - Drop MC33XS2410_PERIOD_MAX, MC33XS2410_PERIOD_MIN defines
  - Drop mc33xs2410_period variable
  - Round down when calculating period and duty cycle
  - Use switch instead of loop when calculating frequency
  - Removed ret variable in mc33xs2410_pwm_get_freq
  - Handle all accesses in a single call to spi_sync_transfer
  - Fix comments in function mc33xs2410_pwm_get_period
  - Fix call pwm_set_relative_duty_cycle(state, ret, 255), instead
    pwm_set_relative_duty_cycle(state, val[1] + 1, 256);
  - Use devm_pwmchip_alloc
  - Fix typo s/Transitition/Transition/
  - Drop driver_data
  - Removed patch for direct inputs from series
  - Tested with PWM_DEBUG enabled, didn't before !

Changes in V4:
  - removed include of math.h, already included in math64.h
  - removed include of mutex.h, no mutexes are used
  - added include of bitfield.h(FIELD_GET, FIELD_PREP), fixes errors
    discovered by kernel test robot
  - cast parameters in DIV_ROUND_UP to u32, fixes errors discovered by
    kernel test robot
