Hi, Changed in v2: The quirk is now wrapped inside an ugly ifdef CONFIG_ACPI :( I don't have better ideas better ideas for this I'm afraid. Side note! I will be away for the next three weeks (plus a few days) starting from Friday (Feb 16). The original message: In order to use xHCI DbC we need to allow the USB to be muxed to xHCI even when the connector is in device role. That's because in DbC mode the xHCI is the USB device controller. In the first patch I'm just adding symlinks between the USB role switches and their USB Type-C connectors. That way the user space can find the correct role switch simply by following the symlink. The second patch modifies cros_ec_typec.c. I'm assigning the PLD (Physical Location of Device) hash of the port to the USB role switch when it's missing from the ACPI tables. That should make sure the first patch always works.
