Exynos5420 based Peach PIT board has 4 NTC thermistors to measure
temperatures at various points on the board.

IIO based ADC becomes the parent and NTC thermistors are the childs,
via the HWMON interface.

Changes since v1:
1. Arranged the ADC node alphabetical
2. Added "status = "okay"" to the ADC node

This patch needs
1. MAX77802 PMIC device tree nodes (for ldo9)
   https://www.mail-archive.com/devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org/msg31430.html
2. Uses the DT documentation for NTC thermistors updated with vendor-prefix

This patch set is tested
1. On Peach PIT board via sysfs entry exposed by hwmon
localhost ~ # cat /sys/class/hwmon/hwmon*/device/temp1_input
37436
36449
38560
38059

2. Backward compatibility is tested by replacing "murata" with "ntc"
   in the dts nodes and running the above test.

Now that Javier has spun his patch, perhaps you can fold the "pi"
version in here too?
