2013-03-04	cpufreq: highbank: do not initialize array with a loop	Emilio López	1	-7/+1
	As uninitialized array members will be initialized to zero, we can avoid using a for loop by setting a value to it.

2013-02-02	cpufreq: instantiate cpufreq-cpu0 as a platform_driver	Shawn Guo	1	-0/+5
	As multiplatform build is being adopted by more and more ARM platforms, initcall function should be used very carefully. For example, when GENERIC_CPUFREQ_CPU0 is built in the kernel, cpu0_cpufreq_driver_init() will be called on all the platforms to initialize cpufreq-cpu0 driver. To eliminate this undesired the effect, the patch changes cpufreq-cpu0 driver to have it instantiated as a platform_driver. Then it will only run on platforms that create the platform_device "cpufreq-cpu0". Along with the change, it also changes cpu_dev to be &pdev->dev, so that managed functions can start working, and module build gets supported too. The highbank-cpufreq driver is also updated accordingly to adapt the changes on cpufreq-cpu0.

2013-02-02	cpufreq / highbank: add support for highbank cpufreq	Mark Langsdorf	1	-0/+115
	Highbank processors depend on the external ECME to perform voltage management based on a requested frequency. Communication between the A9 cores and the ECME happens over the pl320 IPC channel.
