Subject: [PATCH 1/6] coresight: remove CORESIGHT_LINKS_AND_SINKS dependencies and selections
Date:   Thu, 17 May 2018 20:20:19 -0500
Message-Id: <20180518012024.22645-1-kim.phillips@arm.com>
In-Reply-To: <20180517070643.GC13919@kroah.com>
References: <20180517070643.GC13919@kroah.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

A coresight topology doesn't need to include links, i.e., a source can
be directly connected to a sink.  As such, selecting and/or depending on
LINKS_AND_SINKS is no longer needed.
