Hi, This patch series removes the use of Exynos4x12 specific support from cpufreq-exynos driver and enables the use of cpufreq-dt driver for this platform. In order to preserve support for Exynos4x12 'boost' mode cpufreq-dt driver is made aware of 'boost' mode frequencies and boost-opps binding is provided. boost-opps binding is currently limited to cpufreq-dt but once there is a need for cpufreq wide and/or generic Linux device support for 'boost' mode cpufreq-dt can be updated to handle the new code without changing the binding itself. The decision to make 'boost' mode support limited to cpufreq-dt driver for now was taken because 'boost' mode is currently a niche feature and code needed for parsing boost-opps binding is minimal and simple. More generic (i.e. separate 'boost' OPPs list in struct device and generic cpufreq convertion of them to freq_table format) support would need far more code and effort to make it work. Doing it without a demonstrated real need would be on overengineering IMHO. This patch series has been tested on Exynos4412 based Odroid-U3 and Trats2 boards.
