Adds PMU DT node for exynos7 SoC.
Signed-off-by: NAbhilash Kesavan <a.kesavan@samsung.com>
Signed-off-by: NKukjin Kim <kgene@kernel.org>

The ADC on exynos7 is quite similar to ADCv2. The differences are as
follows:
	- exynos7-adc has 8 input channels (as against 10 in ADCv2).
	- exynos7 does not include an ADC PHY control register.
	- Some ADC_CON2 register bits being used in ADCv2 are listed as
	  reserved in exynos7-adc. This results in a different init_hw
	  function for exynos7.

This patch add support for s3c2410/s3c2416/s3c2440/s3c2443 ADC. The s3c24xx
is alomost same as ADCv1. But, There are a little difference as following:
- ADCMUX register address
- ADCDAT mask (10 bit or 12 bit ADC resolution according to SoC version)
- s3c24xx/s3c64xx has not included ADC_PHY enable register

The ADC in s3c64xx is almost the same as exynosv1, but

But, the driver extensively uses "NTC" as the vendor name.

This patch corrects the vendor name also updates the

Note: Drivers continue to support the previous compatible strings
but further addition of these compatible strings in device tree
is deprecated.

This patch adds device tree node for the SYSREG registers block
found in Samsung S5P/Exynos SoC series. The SYSREG module
generates control signals for the ARM CPU and various IP blocks
and buses. SYSREG block registers are exposed through APB bus
interface. A sysreg device tree node is to be associated with
mfd syscon driver and all SYSREG clients should use regmap
interface it provides. It allows to eliminate any possible races
and conflicts should different drivers attempt to concurrently
access same register.
