13Description:
14		(RO) When a host bridge has established a secure connection via
15		the platform TSM, symlink appears. The primary function of this
16		is have a system global review of TSM resource consumption
17		across host bridges. The link points to the endpoint PCI device
18		and matches the same link published by the host bridge. See
19		Documentation/ABI/testing/sysfs-devices-pci-host-bridge.
