Subject[PATCH v3 1/2] dt-bindings: usb: Add microchip USB5807 HUB
Date
The USB5807 is a 7-port USB 3.1 hub that can be configured by I2C.
This driver resets the chip, optionally allows D+/D- lines to be
swapped in the devicetree config, and then sends an ATTACH command to
put the device in operational mode.

Signed-off-by: Mike Looijmans <mike.looijmans@topic.nl>

Changes in v3:
Add minItems

Changes in v2:
Rename to microchip,usb5807.yaml
Remove reset-gpios description
Add maxItems
