[PATCH v3 0/6] Support PWM polarity control

[Bhuvanchandra DV]

Changes since v3:

- Set pwm->args.polarity, before using pwm_set_polarity() function as suggested
  by Lukasz.
- Squash Lukasz patch( https://lkml.org/lkml/2016/10/6/32 )

Tested on Toradex Colibri iMX6S module.

Changes since v2:

- Picked the stalled patchset[1] from Lothar Wassmann which adds the basic
  support for polarity control on imx-pwm driver and adds backward compatibility
  support for devices which does not have polarity control feature.

Changes since Lothars v6:

- Squash Lukasz patch[2].
