Subject: [PATCH 07/25] coresight: replicator: Cleanup device tracking
Date: Wed, 20 Mar 2019 18:49:24 +0000 [thread overview]
Message-ID: <1553107783-3340-8-git-send-email-suzuki.poulose@arm.com> (raw)
In-Reply-To: <1553107783-3340-1-git-send-email-suzuki.poulose@arm.com>
In preparation to use a consistent device naming scheme,
clean up the device link tracking in replicator driver.
Use the "coresight" device instead of the "real" parent device
for all internal purposes. All other requests (e.g, power management,
DMA operations) must use the "real" device which is the parent device.
