*	cpufreq: arm_big_little: free OPP table created during ->init()	Viresh Kumar	2014-12-02	1	-1/+4
\| \| \| \| \| \| \| \|	OPP layer now supports freeing of OPPs and we should free them once they aren't useful anymore. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
*	cpufreq: arm_big_little: add in-kernel switching (IKS) support	Viresh Kumar	2013-10-31	1	-5/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch adds IKS (In Kernel Switcher) support to cpufreq driver. This creates a combined freq table for A7-A15 CPU pairs. A7 frequencies are virtualized and scaled down to half the actual frequencies to approximate a linear scale across the combined A7+A15 range. When the requested frequency change crosses the A7-A15 boundary a cluster switch is invoked. Based on earlier work from Sudeep KarkadaNagesha.

*	cpufreq: ARM big LITTLE: Move cpu_to_cluster() to arm_big_little.h	Viresh Kumar	2013-05-12	1	-0/+5
\| \| \| \| \| \| \| \| \|	The cpu_to_cluster() function may be used by glue drivers, so it's better to keep it in arm_big_little.h. [rjw: Changelog] Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
*	cpufreq: ARM big LITTLE: Add generic cpufreq driver and its DT glue	Viresh Kumar	2013-04-02	1	-0/+40
	big LITTLE is ARM's new Architecture focussing power/performance needs of modern world. More information about big LITTLE can be found here: http://www.arm.com/products/processors/technologies/biglittleprocessing.php http://lwn.net/Articles/481055/ In order to keep cpufreq support for all big LITTLE platforms simple/generic, this patch tries to add a generic cpufreq driver layer for all big LITTLE platforms. The driver is divided into two parts: - Core driver: Generic and shared across all big LITTLE SoC's - Glue drivers: Per platform drivers providing ops to the core driver This patch adds in a generic glue driver which would extract information from Device Tree. Future SoC's can either reuse the DT glue or write their own depending on the need.
