[PATCH 0/2] Add support for downstream port reset(DPR)

[Sanath S]

Tunnels created by boot firmware results in incorrect PCI resource
allocation, which results in failure of extending daisy chain.

This series aligns with windows behaviour of performing a teardown of
tunnels and resetting the downstream ports using DPR during the init
sequence.

Sanath S (2):
  thunderbolt: Introduce tb_switch_reset_ports(), tb_port_reset() and
    usb4_port_reset()
  thunderbolt: Teardown tunnels and reset downstream ports created by
    boot firmware
