From 5de6e94a298576c2774ba43c0c3b0a0410cd100e Mon Sep 17 00:00:00 2001 From: Sudeep KarkadaNagesha Date: Mon, 17 Jun 2013 15:07:28 +0100 Subject: [PATCH] cpufreq: highbank-cpufreq: remove device tree parsing for cpu nodes Now that the cpu device registration initialises the of_node(if available) appropriately for all the cpus, parsing here is redundant. This patch removes all DT parsing and uses cpu->of_node instead.
