Subject: [PATCH v4 0/3] Fix bugs in kona pwm driver and pwm core

This patchset fixes a number of bugs in the Broadcom Kona pwm driver. It also 
fixes a bug in the pwm core where the state was incorrect on failed calls to
enable.

Changes from v3:
- Removed setting the pwm set to disabled if enable fails. This is now
  done in the pwm core.
- Removed previous change in kona_pwmc_config() that returned right away if
  the state was disabled. The loop needs to execute to ensure that the period
  and duty cycle are valid. Delaying this check to when the pwm is enabled is 
  incorrect.
- Added comments to clarify code.
- Changed commit messages to more accurately reflect the code changes.

Jonathan Richardson (3):
  pwm: kona: Fix incorrect config, disable, and polarity procedures
  pwm: kona: Remove setting default smooth type and polarity for all
    channels
  pwm: core: Set enable state properly on failed call to enable
