Hi Krzysztof, Thanks for your review comments.

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. Signed-off-by: Anand Moon <linux.amoon@gmail.com> --- 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. --- .../devicetree/bindings/usb/vialab,vl817.yaml | 69 +++++++++++++++++++ 1 file changed, 69 insertions(+) create mode 100644 Documentation/devicetree/bindings/usb/vialab,vl817.yaml
