From 8025395f39c97e332362c24f7c33c86acdd4cd90 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Wed, 10 Jul 2013 15:35:26 +0200 Subject: [PATCH] ARM: ux500: cpuidle: Instantiate the driver from platform device To break the dependency on the "id.h" file we move the cpuidle driver to a platform device. Now we only call the probe() on this driver if we find a corresponding platform device (which is spawned from the PRCMU MFD driver).
