I've a plan to create a common file (cros-exynos-peach.dts) for
exynos5420-peach-pit.dts and exynos5800-peach-pi.dts
And add the ADC nodes directly into that.
In favor of the above, can you abandon the following patches
1. [PATCH 3/4 v2] ARM: DTS: use new compatible string for thermistors in trats2
http://www.spinics.net/lists/linux-samsung-soc/msg33037.html
2. [PATCH 4/4 v2] ARM: DTS: Add NTC thermistor nodes to Exynos5420
based Peach_PIT
