From 18be496c921823b435c06c08474e6a259c13822d Mon Sep 17 00:00:00 2001 From: David Anders Date: Tue, 15 Mar 2011 19:10:27 +0000 Subject: OMAP4: PandaBoard: remove unused power regulators the pandaboard does not use the VUSIM or VAUX1 power regulators on the TWL6030 and are left floating. if the VUSIM and VAUX1 power regulators are initilized, noise on the unloaded regulators generates an overcurrent interrupt causing the system to power down. this patch removes the initialization of the unused power regulators of VUSIM and VAUX1.
