[ Upstream commit e2b69180431968250bf3c0c581155f1b37d057c1 ]
SolidRun HummingBoard-T has two options for M.2 connector, supporting either PCI-E or USB-3.1 Gen 1 - depending on configuration of a mux on the serdes lane. The required configurations in device-tree were modeled as overlays.
The USB-3.1 overlay uses /delete-property/ to unset a boolean property on the usb controller limiting it to USB-2.0 by default. Overlays can not delete a property from the base dtb, therefore this overlay is at this time useless.
Convert both overlays into full dts by including the base board dts. While the pcie overlay was functional, both are converted for a consistent user experience when selecting between the two mutually exclusive configurations.
