Subject: arm64: dts: hisilicon: Add usb mux hub for hikey960
|
||
|
|
|
||
|
|
Add dt bindings for Kirin 960 USB HUB. Such board comes with an
|
||
|
|
integrated USB HUB provided via a Microchip USB5734 4-port high-speed
|
||
|
|
hub controller.
|
||
|
|
|
||
|
|
[mchehab: modified it to adapt to the merged DT schema]
