Subject: [PATCH v4 19/19] cpufreq: pmac32-cpufreq: remove device tree parsing for cpu nodes
Date: Tue, 20 Aug 2013 10:30:21 +0100 [thread overview]
Message-ID: <1376991021-12160-20-git-send-email-Sudeep.KarkadaNagesha@arm.com> (raw)
In-Reply-To: <1376991021-12160-1-git-send-email-Sudeep.KarkadaNagesha@arm.com>
From: Sudeep KarkadaNagesha <sudeep.karkadanagesha@arm.com>
Now that the cpu device registration initialises the of_node(if available)
appropriately for all the cpus, parsing here is redundant.
This patch removes DT parsing and uses cpu->of_node instead.
