Currently, this "arm-scmi" platform device is added to the root of the platform bus since no parent is assigned. However, the transport platform device, created from the "firmware:scmi" node in the device tree, should be considered its parent. Ensure that the parent device is correctly set for the "arm-scmi" platform device, aligning it with the correct transport hierarchy. This will be more useful on systems with multiple transport and/or SCMI firmware instances as the hierarchy is maintained correctly.
