Genesys Logic GL852G is a 4-port USB 2.0 STT hub that has a reset pin to
toggle and a 5.0V core supply exported though an integrated LDO is
available for powering it.

Add the support for this hub, for controlling the reset pin and the core
power supply.

[PATCH v2 6/9] dt-bindings: usb: Add binding for Via lab VL817 hub controller

[Anand Moon]

The VIA Lab VL817 is a USB 3.1 Gen 1 hub and USB 2.0 hub
controller that features 4 downstream ports and 1 otg, with
an internal 5V regulator and has external reset pin.

Add a device tree binding for its USB protocol part.
The internal LDO is not covered by this and can just be modelled
as a fixed regulator.

Add combo of USB 2.0 and USB 3.0 root hub using peer-hub.

v2 - fix the compatible string and fix the $id
   - update the commit message.
   - update the example for use peer-hub node because it
     combo of USB 2.0 and USB 3.0 hub.
   - rename the yaml file from vialab,vl817q7.yaml to vialab,vl817.yaml
     as q7 suffix is ued for USB 3.1 and q5 suffix is used for USB 2.0.

Subject: drop second/last, redundant "binding for". The "dt-bindings"
prefix is already stating that these are bindings.
