Paul Bolle cb7063f453 PM / devfreq: remove checks for CONFIG_EXYNOS_ASV
Checks for CONFIG_EXYNOS_ASV were added in v3.3. But the related Kconfig
symbol has never been added to the tree. Remove these checks, as they
always evaluate to false.

Chanwoo Choi ba778b374d PM / devfreq: exynos4: use common PPMU code
This patch converts exynos4_bus driver to use common PPMU code
(exynos_ppmu.c) instead of individual functions related to PPC
because PPMU is integrated module with both PPC and Bus event
generator.  When using PPMU to get bus performance read/write
event exynos4_bus driver deson't need to consider memory type.

Linus Torvalds f2c73464d7 ARM: SoC cleanups for 3.14
This is the branch where we usually queue up cleanup efforts, moving
 drivers out of the architecture directory, header file restructuring,
 etc. Sometimes they tangle with new development so it's hard to keep it
 strictly to cleanups.
 
 Some of the things included in this branch are:
 
 * Atmel SAMA5 conversion to common clock
 * Reset framework conversion for tegra platforms
  - Some of this depends on tegra clock driver reworks that are shared with Mike
    Turquette's clk tree.
 * Tegra DMA refactoring, which are shared branches with the DMA tree.
 * Removal of some header files on exynos to prepare for multiplatform
