From 8b8e2ef328c3378c74fb4347f66df8e58feeaf46 Mon Sep 17 00:00:00 2001 From: David Anders Date: Fri, 18 Mar 2011 16:53:20 -0700 Subject: [PATCH] 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.
