Subject: [PATCH 23/53] FROMLIST(v4): dt-bindings: usb: Add the binding example
|
|
for the Genesys Logic GL3523 hub
|
|
|
|
Add the binding example for the USB3.1 Genesys Logic GL3523
|
|
integrates with USB 3.1 Gen 1 Super Speed and USB 2.0 High-Speed
|
|
hub.
|
|
|
|
Onboard USB hub supports USB 3.x and USB 2.0 peer controllers.
|
|
which has a common reset pin and power supply.
