From f6575c90f6fc637697f130ea4a05892296c9a473 Mon Sep 17 00:00:00 2001 From: Vaibhav Bedia Date: Tue, 29 Jan 2013 16:45:07 +0530 Subject: [PATCH] ARM: DTS: AM33XX: Add nodes for OCMC RAM and WKUP-M3 Since AM33XX supports only DT-boot, this is needed for the appropriate device nodes to be created. Note: OCMC RAM is part of the PER power domain and supports retention. The assembly code for low power entry/exit will run from OCMC RAM. To ensure that the OMAP PM code does not attempt to disable the clock to OCMC RAM as part of the suspend process add the no_idle_on_suspend flag.
