[PATCH 0/4] Add framework to support clkout

[Tushar Behera <tushar.behera-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>]

The MUX/GATE register for XCLKOUT doesn't resides within PMU domain,
this can be accessed through a regmap provided by syscon driver. Adding
another clock provider to handle regmap based handing of XCLKOUT.

Dependency:
1. [PATCH v3] mfd: syscon: Support early initialization
http://article.gmane.org/gmane.linux.kernel/1679446

Also we need to find a suitable place to call early_syscon_init(), after
the device tree has been unflattened and before clock initialization.

While testing, I called this before of_clk_init() in arch/arm/kernel/time.c,
but that place is too generic. Calling anywhere from exynos.c is not
working ATM.
