This patch adds the RTC (Real Time Clock) and ADC (Analog Digital Converter)
Device Tree node for exynos3250-artik5 module. The RTC is used for wakeup
source and the ADC is used to read the analog data such as battery temperature.

ADC need to connect the some H/W device such as battery. So, this patch just
adds the default setting (clock, regulator).

No thermistors, status non-okay. What is provided here?

Same comment as for previous patch - just squash it. Splitting brings no
benefits and makes it more difficult to see bigger picture.

BR,

The some device are not connected for ADC line on artik5-eval board.
This dt node just initialize the basic setting (clock,regulator) ADC of exynos3250 SoC.
(I'll change the board name from artik5-devel to artik5-eval on v2 patchset)

The vdd-supply for ADC is already fixed on artik5 module.

Okay. I'll merge it with 5/10 patch.
