Subject: [PATCH v3 3/3] arm64: dts: juno: add missing CoreSight STM component
Date: Thu, 12 Jan 2017 15:20:10 +0000 [thread overview]
Message-ID: <1484234410-7670-4-git-send-email-sudeep.holla@arm.com> (raw)
In-Reply-To: <1484234410-7670-1-git-send-email-sudeep.holla@arm.com>
From: Mike Leach <mike.leach@linaro.org>
This patch adds the missing CoreSight STM component definition to the
device tree of all the juno variants(r0,r1,r2)
STM component is connected to different funnels depending on Juno
platform variant.
Signed-off-by: Mike Leach <mike.leach@linaro.org>
[sudeep.holla at arm.com: minor changelog update and reorganising the STM
node back into juno-base.dtsi to avoid duplication]
