If this does depend on patch 1/3 or 2/3... this patch feels a bit big to apply to the MFD tree. Perhaps patch 1/3 and 2/3 could be applied alone to a topic branch in the MFD tree so I can merge that into the Tegra tree in order to apply this?

This patch is independent from 1/3 and 2/3, so you can apply it to the Tegra tree. The relevant DT change for 2/3 is included in 2/3...

Set the parent of the regulators LDO2 to LDO9 according to the schematic. Set the base voltage to 3.3V, there is only 3.3V on the module itself. Set the Core and CPU voltage to the specified voltages of 1.2V and 1.0V respectivly. LDO6 should deliver 2.85V. The attached peripherals were not in use so far.
