Subject: [PATCH V5 6/9] ARM: mxs: Provide regulator to pwm-backlight
Date: Mon, 25 Mar 2013 18:21:50 -0700 [thread overview]
Message-ID: <1364260913-25490-7-git-send-email-achew@nvidia.com> (raw)
In-Reply-To: <1364260913-25490-1-git-send-email-achew@nvidia.com>
The pwm-backlight driver now takes a mandatory regulator that is gotten
during driver probe. Initialize a dummy regulator to satisfy this
requirement.
Signed-off-by: Andrew Chew <achew@nvidia.com>

Moved backlight power regulator into top-level regulators node.
