From 87b94a43d69ec0760b94f2753b7cafc6cb14b034 Mon Sep 17 00:00:00 2001 From: Lubomir Popov Date: Wed, 20 Nov 2013 15:32:17 +0200 Subject: [PATCH] ARM: OMAP4: Fix bug in omap4470_volts struct The struct incorrectly referenced SMPS1 for all three power domains. Fixed this by using SMPS2 and SMPS5 as appropriate. Add some comments and choose voltage values that correspond to voltage selection codes.
