From ca7255614e0861e36480103f4a402a115803d7b5 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 16 Mar 2009 19:36:34 +0000 Subject: regulator: Support disabling of unused regulators by machines At present it is not possible for machine constraints to disable regulators which have been left on when the system starts, for example as a result of fixed default configurations in hardware. This means that power may be wasted by these regulators if they are not in use. Provide intial support for this with a late_initcall which will disable any unused regulators if the machine has enabled this feature by calling regulator_has_full_constraints(). If this has not been called then print a warning to encourage users to fully specify their constraints so that we can change this to be the default behaviour in future.
