In summary, there is a common .dtsi file for Daisy based boards (arch/arm/boot/dts/exynos5250-cros-common.dtsi) but it seems it turned out to do more harm than good since having a single .dtsi for all the common DTS chunks is not quite flexible. As more boards gets introduced you have to start moving stuff from the common .dtsi file to the board .dts. The same was tried to do for OMAP2+ boards and it turned out that you need to either a) create a hierarchy of .dtsi files to model all the different board combinations that have similar fragments or b) split out isolated DTS fragments on an .dtsi and include a set of this fragments. For an example of a) you can take a look to arch/arm/boot/dts/omap3-overo* and for b) to arch/arm/boot/dts/omap-gpmc-smsc9*.dtsi. For a Peach Pit/Pi specific example of b) you can look at the recent arch/arm/boot/dts/cros-ec-keyboard.dtsi file that Doug added for Peach Pit/Pi keyboard. Personally I think that b) is a more flexible and reusable approach. So, maybe instead of creating a cros-exynos-peach.dts to contain all the common DT nodes you can add a cros-ec-thermistor.dsti file that only includes the ADC based Thermistor nodes?
