2019-04-16dt-bindings: usb: Convert USB HCD generic binding to YAMLMaxime Ripard
The USB HCD generic binding is used by many USB host bindings. In order to allow the DT validation to happen on those, let's create a YAML description for that generic binding that can be referenced later on.

2018-03-09dt-bindings: usb: add the documentation for USB HCDsMartin Blumenstingl
A USB HCD may have several PHYs which need to be configured before the the HCD starts working. This adds the documentation for such a USB HCD as well as a reference to the new "usb-hcd.txt" from all bindings that implement a USB HCD which support one USB PHY per port.
