+Description:
+ "tsmN" is a device that represents the generic attributes of a
+ platform TEE Security Manager. It is typically a child of a
+ platform enumerated TSM device. /sys/class/tsm/tsmN/uevent
+ signals when the PCI layer is able to support establishment of
+ link encryption and other device-security features coordinated
+ through a platform tsm.

+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.
