Merge tag 'samsung-soc64-4.6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into next/arm64

Samsung Exynos ARM64 improvements for v4.6:
1. Remove separate ARCH_EXYNOS7 symbol and consolidate it into
   one ARCH_EXYNOS.

This depends on clk tree: removal of last presence of ARCH_EXYNOS7.

* tag 'samsung-soc64-4.6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux:
  arm64: EXYNOS: Consolidate ARCH_EXYNOS7 symbol into ARCH_EXYNOS
  clk: samsung: Don't build ARMv8 clock drivers on ARMv7
  clk: samsung: Enable COMPILE_TEST for Samsung clocks
  clk: Move vendor's Kconfig into CCF menu section
  clk: mediatek: Fix memory leak on clock init fail
  clk: move the common clock's to_clk_*(_hw) macros to clk-provider.h
  clk: xgene: Remove return from void function
  clk: xgene: Add SoC and PMD PLL clocks with v2 hardware
  Documentation: Update APM X-Gene clock binding for v2 hardware
  clk: s2mps11: remove redundant code
  clk: s2mps11: remove redundant static variables declaration
  clk: s2mps11: allocate only one structure for clock init
  clk: s2mps11: merge two for loops in one
  clk-divider: make sure read-only dividers do not write to their register
  clk: tango4: rename ARCH_TANGOX to ARCH_TANGO
  clk: scpi: Fix checking return value of platform_device_register_simple()
  clk: mvebu: Mark ioremapped memory as __iomem
