Subject: [PATCH 0/4] Add CIX Sky1 Cadence USB3 support
Date: Mon, 11 May 2026 10:42:40 +0800 [thread overview]
Message-ID: <20260511024244.981941-1-peter.chen@cixtech.com> (raw)
This series adds library support for cdns3 platform driver as well as the
first user CIX Sky1 USB3. It is the follow-up of Arnd's suggestion [1] for
helping cdns3 module dependencies and new developers working on it.
The final two patches document the Sky1 binding and describe the USB4/USB5
controller instances in the Sky1 device tree and enable them on the Radxa
Orion O6 board.
