Subject: [PATCH 2/2] arm64: dts: mba93xxca: Add USB support
Date: Tue, 23 Apr 2024 11:33:41 +0200 [thread overview]
Message-ID: <20240423093341.1927592-2-alexander.stein@ew.tq-group.com> (raw)
In-Reply-To: <20240423093341.1927592-1-alexander.stein@ew.tq-group.com>
This adds support for both USB host and USB Type-C ports. This includes
the on-board USB hub. Remove the gpio-hog for USB_RESET# as well.
