Subject: [PATCH 08/21] microblaze: get cpu node with of_get_cpu_node
Date:   Wed,  5 Sep 2018 14:37:25 -0500
Message-Id: <20180905193738.19325-9-robh@kernel.org>
In-Reply-To: <20180905193738.19325-1-robh@kernel.org>

Precedence: bulk

"device_type" use is deprecated for FDT though it has continued to be used
for nodes like cpu nodes. Use of_get_cpu_node() instead which works using
node names by default. This will allow the eventually removal of cpu
device_type properties.

Also, fix a leaked reference by adding a missing of_node_put.

Please ack and I will take via the DT tree. This is dependent on the
first 2 patches.
