cpufreq: highbank-cpufreq: remove device tree parsing for cpu nodes (5de6e94a) · Commits · 戴 / test

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. Cc: Mark Langsdorf <mark.langsdorf@calxeda.com> Acked-by:
