	Currently when performing random CPU hot-plugs and suspend-to-ram(S2R) on systems using arm_big_little cpufreq driver, we get warnings similar to something like below: cpu cpu1: _opp_add: duplicate OPPs detected. Existing: freq: 600000000, volt: 800000, enabled: 1. New: freq: 600000000, volt: 800000, enabled: 1 This is mainly because the OPPs for the shared cpus are not set. We can just use dev_pm_opp_of_cpumask_add_table in case the OPPs are obtained from DT(arm_big_little_dt.c) or use dev_pm_opp_set_sharing_cpus if the OPPs are obtained by other means like firmware(e.g. scpi-cpufreq.c) Also now that the generic dev_pm_opp{,_of}_cpumask_remove_table can handle removal of opp table and entries for all associated CPUs, we can re-use dev_pm_opp{,_of}_cpumask_remove_table as free_opp_table in cpufreq_arm_bL_ops. This patch makes necessary changes to reuse the generic OPP functions for {init,free}_opp_table and thereby eliminating the warnings.

2015-09-28	cpufreq: arm_big_little: add SCPI interface driver	Sudeep Holla
	On some ARM based systems, a separate Cortex-M based System Control Processor(SCP) provides the overall power, clock, reset and system control including CPU DVFS. SCPI Message Protocol is used to communicate with the SCPI. This patch adds a interface driver for adding OPPs and registering the arm_big_little cpufreq driver for such systems.
