From 19ac17c031ce37c697966b6513d611f9e322a290 Mon Sep 17 00:00:00 2001 From: Sudeep Holla Date: Thu, 12 Jan 2017 11:53:35 +0000 Subject: [PATCH] arm64: dts: juno: refactor CoreSight support on Juno r0 Currently the Coresight components are supported only on Juno r0 variant. In preparation to add support to Juno r1/r2 variants, this patch refactors the existing coresight device nodes so that r1/r2 support can be added easily. It also cleans up some of the device node names which were previously named so as they were confused as the labels rather than the node names.
