From 02bbde7849e68e193cefaa1885fe0df0f03c9fcd Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Sun, 17 Feb 2013 20:03:27 +0000 Subject: [PATCH] Revert "of: use platform_device_add" This reverts commit aac73f34542bc7ae4317928d2eabfeb21d247323. That commit causes two kinds of breakage; it breaks registration of AMBA devices when one of the parent nodes already contains overlapping resource regions, and it breaks calls to request_region() by device drivers in certain conditions where there are overlapping memory regions. Both of these problems can probably be fixed, but it is better to back out the commit and get a proper fix designed before trying again.
