Subject: [PATCH v3 0/6] Support PWM polarity control
Date: Fri, 7 Oct 2016 20:41:23 +0530 [thread overview]
Message-ID: <20161007151129.6043-1-bhuvanchandra.dv@toradex.com> (raw)
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].

Bhuvanchandra DV (3):
arm: dts: imx7: Update #pwm-cells for PWM polarity control
arm: dts: imx7-colibri: Use pwm polarity control
arm: dts: imx7-colibri: Use enable-gpios for BL_ON
Lothar Wassmann (3):
pwm: print error messages with pr_err() instead of pr_debug()
pwm: core: make the PWM_POLARITY flag in DTB optional
pwm: imx: support output polarity inversion
