Subject: [PATCH 3/5] arm64: dts: rockchip: add usb3 controller node for RK3328
SoCs

RK3328 has one USB 3.0 OTG controller which uses DWC_USB3
core's general architecture. It can act as static xHCI host
controller, static device controller, USB 3.0/2.0 OTG basing
on ID of USB3.0 PHY.

Subject: [PATCH 5/5] usb: dwc2: disable power_down on rockchip devices

The bug would let the usb controller enter partial power down,
which was formally known as hibernate, upon boot if nothing was plugged
in to the port. Partial power down couldn't be exited properly, so any
usb devices plugged in after boot would not be usable.

Before the name change, params.hibernation was false by default, so
_dwc2_hcd_suspend() would skip entering hibernation. With the
rename, _dwc2_hcd_suspend() was changed to use params.power_down
to decide whether or not to enter partial power down.

Since params.power_down is non-zero by default, it needs to be set
to 0 for rockchip devices to restore functionality.

This bug was reported in the linux-usb thread:
REGRESSION: usb: dwc2: USB device not seen after boot

The commit that caused this regression is:
