[PATCH v4 0/7] ARM: Exynos: Enable device tree support for MCT controller

[Thomas Abraham]

Changes since v3:
- Based on Stephen Warren's CONFIG_CLKSRC_OF patches (merged from arm-soc
  'timer/cleanup' branch).
- Moved the mct driver from mach-exynos to drivers/clocksource

Changes since v2:
- Rebased to linux 3.8-rc1

Changes since v1:
- Includes changes suggested by Sylwester Nawrocki <sylvester.nawrocki at gmail.com>

This patch series adds device tree support for Exynos4/5 MCT controller and
moves the MCT driver from mach-exynos to drivers/clocksource. These patches
are based on Stephen Warren's CONFIG_CLKSRC_OF patches which were merged from
the 'timer/cleanup' branch of the arm-soc tree. It also depends on the
following two patches.

- http://lists.infradead.org/pipermail/linux-arm-kernel/2013-January/143119.html

This patch series has been tested on Exynos4210 based Origen board, Exynos4412
based Origen board and Exynos5250 based SMDK board.

Thomas Abraham (7):
  ARM: Exynos: add a register base address variable in mct controller driver
  ARM: Exynos: prepare an array of MCT interrupt numbers and use it
  ARM: Exynos: add device tree support for MCT controller driver
  ARM: Exynos: allow dt based discovery of mct controller using clocksource_of_init
  ARM: dts: add mct device tree node for all supported Exynos SoC's
  ARM: Exynos: remove static io-remapping of mct registers for Exynos5
  ARM: Exynos: move mct driver to drivers/clocksource
