From 7a4f26097d389c16c9956bc03b81532698d97d64 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Wed, 19 Sep 2012 19:31:19 +0200 Subject: ARM: ux500: de-globalize This removes the file from the global kernel include scope, making it a pure mach-ux500 detail. All ASIC specifics needed by drivers shall henceforth be passed from either platform data or the device tree. Cc: Rafael J.
