Then some day maybe we can have common slot handling code. With that, here you just need: vpcie3v3-supply: true > + > + vpcie1v8-supply: > + description: 1.8v regulator phandle for the endpoint device > + > + vpcie0v9-supply: > + description: 0.9v regulator phandle for the endpoint device These are not standard. They go to a soldered down device or non-standard connector? For the former, the device should really be described in DT and the supplies added there. Mini PCIe connector also has 1.5V supply.
