[PATCH 0/2] dt-bindings: usb: genesys,gl850g: describe downstream facing ports

[Dmitry Baryshkov]

In order to describe connections between Genesys GL850G hub and
corresponding Type-C connectors on some of laptops (e.g. Lenovo Yoga
C630), follow example of RTS5411 and describe downstream facing ports.

[PATCH 1/2] dt-bindings: usb: genesys,gl850g: use usb-hub.yaml

[Dmitry Baryshkov]

In order to reduce duplication, switch GL850G to use USB hub bindings
instead of using simple usb-device.yaml

[PATCH 2/2] dt-bindings: usb: genesys,gl850g: add downstream facing ports

[Dmitry Baryshkov]

In order to describe connections between Genesys GL850G hub and
corresponding Type-C connectors, follow example of RTS5411 and describe
downstream facing ports. Unline normal case of ports being connected to
a USB device, hotplug ports use OF graph representation.
