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