From: Biju Das <biju.das.jz@xxxxxxxxxxxxxx>
Add RZ/G3E USB3.2 Gen1 Host Controller and PHY support. The USB3HOST
is compliant with the Universal Serial Bus 3.2 Specification Revision 1.0.
- Supports 1 downstream USB receptacles
- Number of SSP Gen2 or SS ports: 1
- Number of HS or FS or LS ports: 1
- Supports Super Speed Plus Gen2x1 (10 Gbps), Super Speed (5 Gbps),
High Speed (480 Mbps), Full Speed (12Mbps), and Low Speed (1.5 Mbps).
- Supports all transfer-types: Control, Bulk, Interrupt, Isochronous, and
these split-transactions.
- Supports Power Control and Over Current Detection.
v1->v2:
* Collected tags.
* Replaced usb30->usb3_0 for clocks and resets.
* Replaced magic numbers with macros iphy driver.
* Added ref to usb-xhci.yaml in USB3 binding patch.
