The hibernation feature enabled for Xilinx Versal NET SoC in DWC3 IP.
As the DWC3 IP supports the hibernation feature, to handle the wakeup
or hibernation interrupt, add host mode "wakeup" interrupt-names
optional property in the binding schema to capture remote-wakeup and
connect/ disconnect event in the hibernation state.
We have a dedicated IRQ line specifically for the hibernation feature.
When the "wakeup" IRQ line is triggered, it initiates a hibernation
interrupt, causing the system to wake up from the hibernation state.

Change in V2:
- Addressed ROB review comments
- Updated name of interrupt-names property with "wakeup"
- Move interrupt-names property from dwc3-xilinx core to dwc3 core.

doc reference errors (make refcheckdocs):
See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/[email protected]
The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.
If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:
pip3 install dtschema --upgrade
Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
