This series does a refactoring by creating dtsi files for the tps65090 PMU that can be included by DT board files that have this component. This not only allow to remove duplicated code but also makes it easier to maintain the tps65090 information.
So the series also improve the tps65090 description by adding regulator constraints information and also the power scheme for some boards that are using a simplistic model for the connection between the regulators in the tps65090. The refactoring was made after Doug Anderson suggestion on a previous patch that just attempted to add the constraints to the Peach machines DTS [0]. Patch 01/06 creates a .dtsi fragment for the tps65090 and patch 02/06 removes the duplicated definitions from the Exynos Snow board. Patch 03/06 creates a fragment that is more specific for the tps65090 usage in Chrome OS machines and patch 04/06 uses it for Peach boards. Patch 05/06 model the real regulators relation instead of the simplistic model that was used before and finally patch 06/06 adds the tps65090 regulators constraints according to the data manual. NOTES: The NVIDIA Tegra114 Dalmore evaluation board also uses this PMU and can be converted to use the .dtsi but I didn't include in this series to avoid unnecessary cross subsystem churn. Once this is included I can post as a follow-up patch. Maybe the Snow can also use the cros-tps65090.dtsi instead of just the tps65090.dtsi but someone with the schematics for this board has to double check and can be done in a follow-up patch as well.
