Subject[PATCH v2 1/2] dt-bindings: usb: generic-ehci: document ignore-oc flag
Date
Over-current reporting isn't supported on some platforms such as bcm63xx.
These devices will incorrectly report over-current if this flag isn't properly
activated.

Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com>

v2: change flag name and improve documentation as suggested by Alan Stern.
