| Support usb hub and usb data role switch of Hisilicon HiKey960 Board. |
| |
| ----------------------------- |
| |
| Required properties: |
| - compatible: "hisilicon,gpio_hubv1" |
| - typec-vbus-gpios: gpio to control the vbus of typeC port |
| - otg-switch-gpios: gpio to switch DP & DM between the hub and typeC port |
| - hub-vdd33-en-gpios: gpio to enable the power of hub |
| - pinctrl-names: pin configuration state name ("default") |
| - pinctrl-0: pinctrl config |
| - usb-role-switch: flags the driver as a role switch provider |
| - ports: two endpoints to connect the usb core role switch provider |
| to the usb-c tcpm driver. |
| |
