In this series of patches we add support for link low power states (CLx).
Low Power states are used to reduce transmitter and receiver power
when a Lane is idle. First we enable it for USB4 devices, then for Titan Ridge
device. No other thunderbolt devices support CLx.

Gil Fine (7):
  thunderbolt: Add TMU unidirectional mode
  thunderbolt: Add CL0s support for USB4
  thunderbolt: Move usb4_switch_wait_for_bit() to switch.c
  thunderbolt: Enable TMU for Titan Ridge device
  thunderbolt: Rename Intel VSC capability
  thunderbolt: Enable CLx for Titan Ridge device
  thunderbolt: Add kernel param for CLx disabling
