From d919501feffa8715147582c3ffce96fad0c7016f Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Thu, 12 Feb 2015 11:37:13 +0200 Subject: [PATCH] ARM: dts: dra7: add minimal l4 bus layout with control module support This patch creates the l4_cfg and l4_wkup interconnects for DRA7, and moves some of the generic peripherals under it. System control module support is added to the device tree also, and the existing SCM related functionality is moved under it.
