From b8845074cfbbd1d1b46720a1b563d7b4240dac21 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Tue, 24 Feb 2015 16:22:45 +0200 Subject: [PATCH] ARM: dts: omap3: add minimal l4 bus layout with control module support This patch creates an l4_core interconnect for OMAP3, 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 node as the clock provider.
