[PATCH v2 0/5] PWM i.MX27 fix disabled state for inverted signals

[Marco Felsch]

Hi,

this small series fixes the pwm disabled behaviour in case of an
inverted pwm signal. The current state is that in such a case the pwm
signal goes to 0V which means logical '1' for inverted pwm signals. IMO
this is wrong and should be fixed.

I've tested my patches on a custom imx6 board which uses the pwm as
backlight.

Each patch has a dedicated changelog so I skip it here.

Comments and testers are welcome :)

Regards,
  Marco

  pwm: imx27: reset the PWM if it is not running
  pwm: imx27: fix disable state for inverted PWMs
  pwm: imx27: wait till the duty cycle is applied
