Subject: [PATCH v1] arm64: dts: ti: verdin-am62: add support for Verdin USB1 interface
Date: Fri,  9 Feb 2024 12:05:00 +0100	[thread overview]
Message-ID: <20240209110500.22193-1-andrejs.cainikovs@gmail.com> (raw)

From: Andrejs Cainikovs <andrejs.cainikovs@toradex.com>

Add support for Verdin USB1 interface, implements role switch
functionality using "gpio-usb-b-connector", VBUS is also now
controlled with "regulator-fixed" using a standard GPIO.
