[PATCH 0/8] cpufreq: add generic cpufreq driver support for Exynos5250/5800 platforms

[Bartlomiej Zolnierkiewicz]

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
