dt-bindings: usb: Fix EIC7700 USB reset's issue

2026-05-22T09:13:19+00:00

The EIC7700 USB requires a USB PHY reset operation; otherwise, the USB
will not work. The reason why the USB driver that was applied can work
properly is that the USB PHY has already been reset in ESWIN's U-Boot.

However, the proper functioning of the USB driver should not be dependent
on the bootloader. Therefore, it is necessary to incorporate the USB PHY
reset signal into the DT bindings.

This patch does not introduce any backward incompatibility since the dts
is not upstream yet. As array of reset operations are used in the driver,
no modifications to the USB controller driver are needed.

dt-bindings: usb: ti,omap4-musb: Drop duplicate 'usb-phy' property constraints

2026-05-22T09:12:57+00:00

The deprecated 'usb-phy' property is documented already in usb.yaml and
doesn't need a type definition here. It just needs constraints on how
many entries there are.

As this is a host controller, reference usb-hcd.yaml which then
references usb.yaml.

dt-bindings: usb: atmel,at91sam9rl-udc: convert to DT schema

2026-04-11T10:02:16+00:00

Convert Atmel High-Speed USB Device Controller (USBA) binding to DT schema.
Changes during conversion:
- Make the "clock-names" property flexible enough to accept the items
  in any order as the existing in tree DTS nodes doesn't follow an order.

Convert Atmel AT91 USB Device Controller (UDC) binding to DT schema.
Changes during conversion:
- Include "atmel,pullup-gpio" and "atmel,matrix" in the properties since
  they are required by existing in-tree DTS definitions.
