Subject: [PATCH 09/14] regulator: pwm: Adjust PWM config at probe time
Date: Fri,  3 Jun 2016 10:23:07 +0200	[thread overview]
Message-ID: <1464942192-25967-10-git-send-email-boris.brezillon@free-electrons.com> (raw)
In-Reply-To: <1464942192-25967-1-git-send-email-boris.brezillon@free-electrons.com>

The PWM attached to a PWM regulator device might have been previously
configured by the bootloader.
Make sure the bootloader and linux config are in sync, and adjust the PWM
config if that's not the case.
