[PATCH v5 15/15] coco: host: arm64: Enable PCI TSM connect callbacks
From: Aneesh Kumar K.V (Arm)
Date: Thu Sep 10 2026 - 10:32:11 EST
The previous patches build up the Arm CCA host device-assignment flow: RMM
pdev creation and teardown, device communication, public-key setup, peer
stream coordination, RMM stream connect/disconnect, and support for both
endpoint and RC endpoint stream types.
Now that the connect and disconnect paths contain the complete setup and
teardown sequence, register them in pci_tsm_ops and drop the __maybe_unused
annotations.
