Hi,
This patch series adds generic arm_big_little_dt cpufreq driver support for Exynos5420/5800 (using the new CPU clock type which allows it). It also: - enhances arm_big_little[_dt] driver with CPU cluster regulator support - fixes CPU clock configuration data and CPU operating points setup for Exynos5800 - adds CPU cluster regulator supplies for ODROID-XU3 board
This patch series has been tested on Exynos5800 based ODROID-XU3 board.
Depends on: - next-20150330 branch of linux-next kernel tree - "[PATCH 0/6] cpufreq: use generic cpufreq drivers for Exynos4210 platform" [1] - "[PATCH 0/6] cpufreq: use generic cpufreq drivers for Exynos4x12 platform" [2] - "[PATCH] cpufreq: exynos: remove dead ->need_apll_change method" [3] - "[PATCH 0/4] cpufreq: use generic cpufreq drivers for Exynos5250 platform" [4]

Changes over Thomas' original v12 code: - split Exynos5420 and Exynos5800 support - moved E5420_[EGL,KFC]_DIV0() macros to clk-exynos5420.c - disabled cpufreq if big.LITTLE switcher support is enabled - enhanced arm_big_little[_dt] driver with CPU cluster regulator support - fixed CPU clock configuration data for Exynos5800 - fixed CPU operating points setup for Exynos5800 - added CPU cluster regulator supplies for ODROID-XU3 board
Changes since v1: - added CPU cluster regulator supply properties to exynos5420-arndale-octa.dts, exynos5420-peach-pit.dts, exynos5420-smdk5420.dts and exynos5800-peach-pi.dts
