From 0e4f417857083f399769491f6e7773d111debd0f Mon Sep 17 00:00:00 2001 From: Amit Daniel Kachhap Date: Tue, 15 Jul 2014 16:32:51 +0530 Subject: regulator: s2mpxxx: Move regulator min/step voltages in common place This is a cleanup patch and moves min/step voltages in a common samsung header file so that they can be used by other s2mpxxx PMIC drivers. Only few required macros are added currently and others can be added if needed.
