Subject: [PATCH v5 15/15] coco: host: arm64: Enable PCI TSM connect callbacks
Date: Thu, 10 Sep 2026 19:35:08 +0530 [thread overview]
Message-ID: <20260910140509.868402-16-aneesh.kumar@kernel.org> (raw)
In-Reply-To: <20260910140509.868402-1-aneesh.kumar@kernel.org>
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.
