From 810ac2a1102880b6c66dc2f26979a896b2d84009 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 25 Nov 2013 15:17:10 -0800 Subject: [PATCH] ARM: OMAP2+: Make n8x0 behave better with device tree based booting Initialize some devices using a late_initcall and test for the device tree based booting for some devices. This way we can keep things working for legacy platform devices when booted with device tree.
