Subject: [PATCH RESEND] ARM: tegra: set regulator full constraints
Date: Thu, 31 Oct 2013 15:05:26 +0800	[thread overview]
Message-ID: <1383203126-3243-1-git-send-email-wni@nvidia.com> (raw)

Set full constraints during machine initialisation, so that the
regulator_get() can get the dummy regulator if the regulator is
physically present and enabled.
Discussed this in the link:
