From 1d597b07b65523fcdb3901fe7a2ab145371ce21b Mon Sep 17 00:00:00 2001 From: Rajendra Nayak Date: Tue, 9 Jul 2013 13:02:15 +0530 Subject: [PATCH] ARM: OMAP: DRA7: Reuse the omap44xx_restart and fix the device instance The omap44xx_restart used on omap4 and omap5 devices can be reused on dra7 devices as well. The device instance however is different across omap5 and dra7 as compared to omap4. So fix this for omap5 as well as dra7.
