From 36aa893775b809ea3b508a225992311582f6379a Mon Sep 17 00:00:00 2001 From: Thomas Abraham Date: Sat, 23 Apr 2016 22:18:12 +0530 Subject: arm: exynos: realign the code to allow support for newer 64-bit platforms The existing Exynos 32-bit platform support needs to be realigned in order to support newer 64-bit Exynos platforms. The driver model will be utlized for drivers on the 64-bit Exynos platforms and so some of the older platform support code would not be required for the newer 64-bit Exynos platforms.
