You need at least these five commits: thunderbolt: Move struct tb_cm to tb.h thunderbolt: Obtain PCIe Device/Function number from DROM thunderbolt: Obtain PCIe Device/Function number via Router Operation thunderbolt: Associate PCI devices with PCIe Adapters thunderbolt: Mark PCIe Adapters on root switch as non-removable on this branch: https://github.com/l1k/linux/commits/thunderbolt_associate_v1 Thanks, Lukas
