From cdc07e96047a89466c52d723a8b62739ad5604eb Mon Sep 17 00:00:00 2001 From: Mike Leach Date: Wed, 11 Jan 2017 20:44:08 +0000 Subject: [PATCH] arm64: dts: juno: add CoreSight support for Juno r1/r2 variants The CoreSight support added for Juno is valid for only Juno r0. The Juno r1 and r2 variants have additional components and alternative connection routes between trace source and sinks. This patch builds on top of the existing r0 support and extends it to Juno r1/r2 variants.
