Allwinner H3 have a its USB PHY0 routed to two USB controllers: one is
a MUSB controller, which can work in peripheral mode, but works badly in
host mode (several hardware will fail on the MUSB controller, even connect
one MUSB controller in peripheral mode to another one in host mode cannot
work); the other is a pair of EHCI/OHCI controller, which can work only
in host mode, but have better compatibillity. The route is controlled in
a register, which we have set it to HCI only when we do not know about
it well.
Add support to route to the best controller according to current USB mode
(host/peripheral).
Note: Currently even if hardware only support hostmode, we should still
enable the MUSB controller, as it controls the USB mode. (Some this kind
of hardware can also work in peripheral mode by settings in the sysfs
node of MUSB, then connect it to another host via a USB Type-A to Type-A
cable.)
Patch 1 adds support for auto routing of PHY0. It's currently only enabled
on H3, but it's easy to extend it to other SoCs which feature this
route control.
Patch 2 adds necessary device tree nodes to the H3 DTSI file. Note: The
phy is not bind for OHCI/EHCI0, as OHCI/EHCI drivers will keep the VBUS
on. Only MUSB driver can properly handle a dual-role PHY.
Patch 3 enables USB OTG functionality on Orange Pi One board, which is
the only H3 board I have that have proper OTG function. It's easy to
enable OTG on other boards with their schematics.

On newer Allwinner SoCs (H3 and after), the PHY0 node is routed to both
MUSB controller for peripheral and host support (the host support is
slightly broken), and a pair of EHCI/OHCI controllers, which provide a
better support for host mode.
Add support for automatically switch the route of PHY0 according to the
status of dr_mode and id det pin.
Only H3 have this function enabled in this patch, as further SoCs will
be tested later and then have it enabled.

Changes in v2:
- Re-route after force session end.
- Drop id_det based on role code in reroute function, as we already
properly set id_det in id_det getting function.

Orange Pi One features a MicroUSB port that can work in both host mode
and peripheral mode.
When in host mode, its VBUS is controlled via a GPIO; when in peripheral
mode, its VBUS cannot be used to power up the board.
Add support for this port.

* [PATCH v2 3/3] ARM: dts: sun8i: enable USB OTG on Orange Pi One

Orange Pi One features a MicroUSB port that can work in both host mode
and peripheral mode.
When in host mode, its VBUS is controlled via a GPIO; when in peripheral
mode, its VBUS cannot be used to power up the board.
Add support for this port.
