According to usb-connector.yaml, typec connector should always use:
- ports property
- with port@0 (required).
This is also true for a single HS port. This removes dtbs_check warning:
stusb1600@28: connector: Unevaluated properties are not allowed ('port'
was unexpected)
Downside is it introduces another warning when building with W=1:
Warning (graph_child_address): /soc/i2c@5c002000/stusb1600@28/connector/
ports: graph node has single child node 'port@0', #address-cells
/#size-cells are not necessary
By removing #address-cells/#size-cells as suggested, another couple of
W=1 warning shows up:
Warning (avoid_default_addr_size): /soc/i2c@5c002000/stusb1600@28/
connector/ports/port@0: Relying on default #address-cells value
Warning (avoid_default_addr_size): /soc/i2c@5c002000/stusb1600@28/
connector/ports/port@0: Relying on default #size-cells value
Is there a clean way or necessary change to reach a clean build and clean
dtbs_check ?
Maybe this kind of concern has already been addressed ?
As far as I understand, the OF graph allows a single port {} node (e.g.
code being reworked here). Could this be added in relevant dtschema, to
address the single HS port use case (usb-connector.yaml) ?
Rob, Krzysztof, do you an idea to figure out this issue ?
Thanks in advance
Alex
