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].
