The keystone SoC can be rebooted in several ways. By external reset
pin, by soft and by watchdogs. To allow keystone SoC reset if
watchdog is triggered we have to enable it in reset mux configuration
register regarding of watchdog configuration. Also we need to set
soft/hard reset we are going to use.
So add keystone reset driver to handle all this stuff.

This patch add new the clock drvier of Exynos3250 SoC based on Cortex-A7
using common clock framework. The CMU (Clock Management Unit) of Exynos3250
control PLLs(Phase Locked Loops) and generate system clocks for CPU, buses,
and function clocks for individual IPs.
The CMU of Exynos3250 includes following clock doamins:
- CPU block for Cortex-A7 MPCore processor
- LEFTBUS/RIGHTBUS block
- TOP block for G3D/MFC/LCD0/ISP/CAM/FSYS/MFC/PERIL/PERIR

drivers: clk: use COMMON_CLK_SAMSUNG for Samsung clock support
This patch replaces PLAT_SAMSUNG with COMMON_CLK_SAMSUNG for Samsung
common clock support. Any Samsung SoC want to use Samsung common clock
infrastructure can simply select COMMON_CLK_SAMSUNG.

This patch moves S3C24XX specific clock Kconfig options into
"clk/samsung/Kconfig" and also removes COMMON_CLK selection from
"mach-s3c24xx/Kconfig" as S3C24XX_COMMON_CLK is selecting it's dependency.

clk: samsung: exynos5420: update clocks for PERIC block
This patch includes,
1] renaming of the HSI2C clocks
2] renaming of spi clocks according to the datasheet
3] fixes for child-parent relationships
4] adding of more clocks related to PERIC block
5] use GATE_IP_* offsets instead of GATE_BUS_*
This patch renames the mux parent arrays as per the naming
convension followed by the other exynos specific clock drivers.
And it also renames "mout_cpu_kfc" clock to "mout_kfc".
This patch adds the required clocks for ARM Mali IP
in Exynos5250.

clk: samsung: exynos4: Use single clock ID for CLK_MDMA gate clocks
Exynos4210 and Exynos4x12 SoCs have the PL330 MDMA IP block clock
defined exactly in same way in documentation. Using different
names for these clocks is a bit misleading. Since there is no users
of CLK_MDMA2 in existing dts files this patch drops CLK_MDMA2 and
replaces it with CLK_MDMA in the driver. This ensures PL330 MDMA
has correct clock assigned on Exynos4x12 SoCs.
