The Thunderbolt controller is integrated into the Ice Lake CPU itself and requires special flows to power it on and off using force power bit in NHI VSEC registers. Runtime PM (RTD3) and Sx flows also differ from the discrete solutions. Now the firmware notifies the driver whether RTD3 entry or exit are possible. The driver is responsible of sending Go2Sx command through link controller mailbox when system enters Sx states (suspend-to-mem/disk). Rest of the ICM firwmare flows follow Titan Ridge.
