e062b57177 clk: exynos4: register clocks using common clock framework
The Exynos4 clocks are statically listed and registered using the
Samsung specific common clock helper functions. Both device tree
based clock lookup and clkdev based clock lookups are supported.

1c4c5fe0b7 clk: samsung: add pll clock registration helper functions
There are several types of pll clocks used in Samsung SoC's and these
pll clocks can be represented as Samsung specific pll clock types and
registered with the common clock framework. Add support for pll35xx,
pll36xx, pll45xx, pll46xx and pll2550x clock types and helper functions
to register them.

721c42a351 clk: samsung: add common clock framework helper functions for Samsung platforms
All Samsung platforms include different types of clock including
fixed-rate, mux, divider and gate clock types. There are typically
hundreds of such clocks on each of the Samsung platforms. To enable
Samsung platforms to register these clocks using the common clock
framework, a bunch of utility functions are introduced here which
simplify the clock registration process. The clocks are usually
statically instantiated and registered with common clock framework.

9fbf0c85a1 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 all machine descriptors for exynos
platforms that were previously set to 'exynos4_timer_init' are now
set to either 'mct_init' or 'clocksource_of_init'.

c371dc60ae 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 support for MCT controller
driver by allowing the driver to retrieve interrupt numbers from
device tree and populating them into this table, thereby supporting
both legacy and dt functionality to co-exist.

a1ba7a7a92 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 obtained from the device
tree.

So in preparation of adding device tree support for MCT controller,
add a new register base address variable that will hold the remapped
MCT controller base address and convert all MCT register read/writes
to use this new variable as the base address instead of the fixed
S5P_VA_SYSTIMER.

While at it, the MCT register offset and bit mask definitions are
moved into the MCT controller driver file since there are no other
consumers of these definitions.
