From e1d6f4729e9fd46efa1029b6e806bb8b6c24e776 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Fri, 25 Feb 2011 15:54:33 -0700 Subject: OMAP: voltage: move plat/voltage.h to mach-omap2/voltage.h At this point in time, there's no reason for this header file to be in plat-omap/include/plat/voltage.h. It should not be included by device drivers, and the code that uses it is currently all under mach-omap2/.
