Subject: [PATCH 01/19] dt-bindings: usb: Add thunderbolt-switch property
Date: Sun, 30 Aug 2026 22:19:19 +0200 [thread overview]
Message-ID: <20260830-b4-apple-soc-tbt-v1-1-44bc9348683c@kernel.org> (raw)
In-Reply-To: <20260830-b4-apple-soc-tbt-v1-0-44bc9348683c@kernel.org>
The USB4/Thunderbolt host routers on Apple Silicon SoCs require cable
and mode details to be provided out-of-band by the Type-C port controller.
Add a thunderbolt-switch property next to the existing orientation and mode
switches which marks a node as handler of these notifications.
