From 0f01565a353e06f1f1d7757b212c51e61c6fea58 Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Thu, 14 Jul 2011 11:12:32 -0700 Subject: [PATCH] OMAP3+: VP: move voltage scale function pointer into struct voltagedomain Function pointer used for actual voltage scaling (e.g. VP force update or VC bypass) is moved from omap_vdd_info into struct voltagedomain, resulting in renames s/vdd->volt_scale/voltdm->scale/ No functional changes.
