Subject[RFC PATCH 06/11] cpufreq: imx6q-cpufreq: remove device tree parsing for cpu nodes
Date
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 all DT parsing and uses cpu->of_node instead.
