[PATCH 00/10] rockchip: Fix misc USB PHY related issues

[Jonas Karlman]

This series tries to fix a few USB PHY related issues found while
working on RK3528/RK3576 USB OTG support.

The first issue is related to Generic PHY reference counting that is not
working correctly for the usbdp or naneng-combphy drivers. Both drivers
xlate ops never initialized phy->id so it could initialize with an old
value from stack when the dwc3-generic driver was probed, causing two
struct phy to be initialized and ending up not sharing same phy->id,
resulting in reference counting for init/exit and power on/off not
working properly.

The second issue is related to the two inno-usb2 and typec drivers
improperly used UCLASS_PHY for their glue/wrapper driver. This could
cause a crash in very specific scenarios, e.g. missing to enable the
otg/host-port node and only leaving the usb2phy node enabled.

The last issue is related to supporting using only USB2 PHY for USB OTG
purpose without having the USB3 PHY initialized, in such scenario the U3
port needs to be disable, more precisely the usb3otg clock source must
change to use UTMI clk instead of the default PIPE clk.

Prior to this series it was the usb3-phy related driver that would
disable the U3 port in special circumstances, e.g. for DP only mode or
when limiting to use high-speed as maximum-speed.

With this series the U3 port instead is disabled early, the USBDP PHY
driver in both U-Boot and Linux will already enable the U3 port when
needed so no changes in behavior is really expected for boards.

Finally, this series also moves usb otg related device tree nodes for
the Generic RK3588 board from the board u-boot.dtsi to the main board
dts.
