Subject: [PATCH 3/3] ARM: DTS: Add common dts file for Peach PIT and PI along
with ADC nodes
DTS files exynos5420-peach-pit.dts and exynos5800-peach-pi.dts
have lots of device tree nodes in common.
This patch creates a cros-exynos-peach.dts file, which can carry the
device tree nodes common across exynos5420-peach-pit.dts and
exynos5800-peach-pi.dts. Starting with ADC based Thermistor nodes.
Also, enables ADC based thermistors for peach_pi and peach_pit.

This patchset needs
"[PATCH v4 00/14] Add Maxim 77802 PMIC support" by "Javier Martinez Canillas"
Posted https://lkml.org/lkml/2014/6/25/668
Intention is to slowly move the common DT nodes across exynos5420-peach-pit.dts
and exynos5800-peach-pi.dts into cros-exynos-peach.dts
I'm unsure of the naming conventions for dts files
Named it "cros-exynos-peach.dts" as below.
used for "cros" + based on "exynos" + boards named "peach" in common.
cat sysfs entries exported by hwmon for 4 thermistors
and verified the values on peach pit.
