Subject: [PATCH v2 3/4] dt-bindings: usb: microchip,usb2514: add support for port vbus-supply
Date: Thu, 27 Mar 2025 18:28:02 +0100 [thread overview]
Message-ID: <20250327172803.3404615-4-m.felsch@pengutronix.de> (raw)
In-Reply-To: <20250327172803.3404615-1-m.felsch@pengutronix.de>
Some PCB designs don't connect the USB hub port power control GPIO and
instead make use of a host controllable regulator. Add support for this
use-case by introducing portX-vbus-supply property.
