From 83a5d6c98af24bb4531dfc05e7c2d3ac2562c6d9 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Thu, 12 Feb 2015 10:25:40 +0200 Subject: ARM: dts: am4372: add minimal l4 bus layout with control module support This patch creates an l4_wkup interconnect for AM43xx, and moves some of the generic peripherals under it. System control module nodes are moved under this new interconnect also, and the SCM clock layout is changed to use the renamed SCM nodea as the clock provider.
