Subject: [PATCH 01/12] coresight replicator: Cleanup programmable replicator naming
Date: Mon, 12 Jun 2017 15:36:40 +0100 [thread overview]
Message-ID: <1497278211-5001-2-git-send-email-suzuki.poulose@arm.com> (raw)
In-Reply-To: <1497278211-5001-1-git-send-email-suzuki.poulose@arm.com>
The Linux coresight drivers define the programmable ATB replicator as
Qualcom replicator, while this is designed by ARM. This can cause confusion
to a user selecting the driver. Cleanup all references to make it
explicitly clear. This patch :
1) Adds a new compatible string for the same, retaining the old one for
compatibility.
2) Changes the Kconfig symbol (since this is not part of any defconfigs)
CORESIGHT_QCOM_REPLICATOR => CORESIGHT_DYNAMIC_REPLICATOR
3) Improves the help message in the Kconfig.
4) Changes the name of the driver :
coresight-replicator-qcom => coresight-dynamic-replicator
