[PATCH v2 2/2] ARM: dts: rockchip: enable usb for rk3229 evb board William Wu <william.wu@rock-chips.com> - 2017-06-02 09:10 +0200

| Subject | [PATCH v2 2/2] ARM: dts: rockchip: enable usb for rk3229 evb board |
| Message-ID | <tNOSD-698-41@gated-at.bofh.it> |
Rockchip's rk3229 evaluation board has one usb otg controller
and three usb host controllers. Each usb controller connect
with one usb2 phy port through UTMI+ interface. And the three
usb host interfaces use the same GPIO VBUS drive. Let's enable
them to support usb on rk3229 evb board.
