Subject: [PATCH v1 1/6] dt-bindings: usb: ci-hdrc-usb2: Document nvidia,external-control property
Date: Mon, 11 May 2026 16:56:56 +0300 [thread overview]
Message-ID: <20260511135703.62470-2-clamor95@gmail.com> (raw)
In-Reply-To: <20260511135703.62470-1-clamor95@gmail.com>
Document the nvidia,external-control property required, for example, for
USB lines in HSIC mode connected to a modem, where the modem requires
precise control over the USB bus to properly enumerate all its stages and
intermediate devices.
