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.

This patch series has been tested on Exynos4412 based Odroid-U3 and
Trats2 boards.

Depends on:
- next-20150806 branch of linux-next kernel tree
- "[PATCH V3 00/16] OPP: Add code to support operating-points-v2 bindings"
  (http://www.spinics.net/lists/arm-kernel/msg435408.html)

Changes since v3
(http://thread.gmane.org/gmane.linux.power-management.general/63464):
- rebased on top of next-20150806 branch of linux-next kernel tree
- made ARCH_EXYNOS config option select thermal support
- made scaling_boost_freqs sysfs attribute available only when boost
  support is enabled
- added Acked-by tag from Viresh to patches #3, #4 and #5
- added Tested-by tag from Tobias to patches #2-5
- added Reviewed-by tag from Krzysztof to patch #4

Changes since v2
(http://thread.gmane.org/gmane.linux.kernel.samsung-soc/46653):
- rebased on top of next-20150730 branch of linux-next kernel tree
- ported over V3 of opp-v2 bindings support patch series
- put cpu0 nodes in alphabetical order in dts files
- added Reviewed-by tags from Javier and Krzysztof
- added Acked-by tag from Sylwester

Changes since v1
(http://thread.gmane.org/gmane.linux.kernel.samsung-soc/44361):
- rebased on top of next-20150629 branch of linux-next kernel tree
- rebased on top of Exynos5250 cpufreq-dt support patch series
- fixed if-statement in exynos4_clk_init() (noticed by Tobias Jakobi)
- ported over opp-v2 bindings (requested by Viresh Kumar)

Best regards,
