commit c4d1ca05b8e68a4b5a3c4455cb6ec25b3df6d9dd upstream.
The xHCI controller on Alpine Ridge LP keeps the whole Thunderbolt controller awake if the host controller is not allowed to sleep. This is the case even if no USB devices are connected to the host.
Add the Intel Alpine Ridge LP product-id to the list of product-ids for which we allow runtime PM by default.
