Subject: [PATCH] ARM: ux300: Fix unimplementable regulation constraints
Date: Sat, 31 Mar 2012 17:44:53 +0100	[thread overview]
Message-ID: <1333212293-6287-1-git-send-email-broonie@opensource.wolfsonmicro.com> (raw)

It doesn't make sense to grant permission to change the status of a
regulator that is also set as always on and similarly it doesn't make
sense to allow a driver to change the voltage of a regulator which can
only be set to a single voltage.
