Subject: [PATCH 07/21] c6x: use for_each_of_cpu_node iterator
Date: Wed,  5 Sep 2018 14:37:24 -0500	[thread overview]
Message-ID: <20180905193738.19325-8-robh@kernel.org> (raw)
In-Reply-To: <20180905193738.19325-1-robh@kernel.org>

Use the for_each_of_cpu_node iterator to iterate over cpu nodes. This
has the side effect of defaulting to iterating using "cpu" node names
in preference to the deprecated (for FDT) device_type == "cpu".

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