Message-ID: <20250102183746.411526-2-e@freeshell.de> (raw)
In-Reply-To: <20250102183746.411526-1-e@freeshell.de>

StarFive JH7110 contains a Cadence USB2.0+USB3.0 controller IP block that
may exclusively use pciephy0 for USB3.0 connectivity. Add the register
offsets for the driver to enable/disable USB3.0 on pciephy0.
