[PATCH v5 0/7] ARM: Exynos: Enable device tree support for MCT controller

Changes since v4: - Rebased to 3.8-rc7 - Updated the MCT controller device nodes to list all the four global timer interrupts generated by the MCT controller. Changes since v3: - Based on Stephen Warren's CONFIG_CLKSRC_OF patches (merged from arm-soc 'timer/cleanup' branch). - Moved the mct

[PATCH 1/7] ARM: Exynos: add a register base address variable in mct controller driver

All the MCT register read/writes use a fixed remapped address S5P_VA_SYSTIMER. With device tree support for MCT controller, it is possible to remove the static remap of the MCT controller address space and do the remap during the initialization of the MCT controller with the physical address

[PATCH 2/7] ARM: Exynos: prepare an array of MCT interrupt numbers and use it

Instead of using soc_is_xxx macro at more than one place in the MCT controller driver to decide the MCT interrpt number to be setup, populate a table of known MCT global and local timer interrupts and use the values in table to setup the MCT interrupts. This also helps in adding device tree

[PATCH 3/7] ARM: Exynos: add device tree support for MCT controller driver

Allow the MCT controller base address and interrupts to be obtained from device tree and remove unused static definitions of these. The non-dt support for Exynos5250 is removed but retained for Exynos4210 based platforms. Cc: Changhwan Youn chaos.y...@samsung.com Signed-off-by: Thomas Abraham

[PATCH 4/7] ARM: Exynos: allow dt based discovery of mct controller using clocksource_of_init

Add entries to __clksrc_of_table so that Exynos MCT controller is discoverable using call to clocksource_of_init. With this change, it would be appropriate to rename the function 'exynos4_timer_init' as 'mct_init' since it aptly describes this function. Additionally, the 'init_time' callback of

[PATCH 6/7] ARM: Exynos: remove static io-remapping of mct registers for Exynos5

[PATCH v6 07/16] ARM: Exynos: Initialize the clocks prior to timer initialization

Since the clock initialization should be completed prior to the mct timer initialization, create a new function 'exynos_init_time' that first sets up the clock and then invokes the timer initialization function. The 'init_time' callback in the board files are updated to invoke this new wrapper
