From 4ddfebd3b0d5b65c69492408bb67fd1202104643 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 13 Sep 2013 19:50:37 +0100 Subject: [PATCH] regulator: core: Provide a dummy regulator with full constraints When a system has said that it has fully specified constraints for its regulators it is still possible that some supplies may be missing, especially if regulator support has been added to a driver after the board was integrated. We can handle such situations more gracefully by providing a dummy regulator. Unless the caller has specifically indicated that the system design may not include a given regulator by using regulator_get_optional() or that it needs its interactions to have an effect using regulator_get_exclusive() provide a dummy regulator if we can't locate a real one. The kconfig option REGULATOR_DUMMY that provided similar behaviour for all regulators has been removed, systems that need it should flag that they have full constraints instead.
