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.
