Yoshihiro Shimoda 39facfa01c usb: gadget: udc: renesas_usb3: Add register of usb role switch 
This patch adds role switch support for R-Car SoCs into the USB 3.0
peripheral driver. Some R-Car SoCs (e.g. R-Car H3) have USB 3.0
dual-role device controller which has the USB 3.0 xHCI host and
Renesas USB 3.0 peripheral.

Unfortunately, the mode change register (DRD_CON) contains
the USB 3.0 peripheral controller side only. So, this renesas_usb3
driver manages the DRD_CON now. However, in peripheral mode, the host
should stop. Also the host hardware needs to reinitialize its own
registers when the mode changes from peripheral to host mode.
Otherwise, the host cannot work correctly (e.g. detect a device
as high-speed).

To achieve this reinitialization by a driver, this driver also
registers a role switch driver to manage the DRD_CON and get
a device pointer of usb 3.0 host from "companion" property of OF.
Then, when the usb role is changed, renesas_usb3_role_switch_set()
will attach/release the xhci-plat driver to reinitialize the host
hardware.

# USB Gadget support on a system involves
# (a) a peripheral controller, and
# (b) the gadget driver using it.
#
# NOTE: Gadget support ** DOES NOT ** depend on host-side CONFIG_USB !!
#
# - Host systems (like PCs) need CONFIG_USB (with "A" jacks).
# - Peripherals (like PDAs) need CONFIG_USB_GADGET (with "B" jacks).
# - Some systems have both kinds of controllers.
#
# With help from a special transceiver and a "Mini-AB" jack, systems with
# both kinds of controller can also support "USB On-the-Go" (CONFIG_USB_OTG).
#
#
# USB Peripheral Controller Support
#
# The order here is alphabetical, except that integrated controllers go
# before discrete ones so they will be the initial/default value:
# - integrated/SOC controllers first
# - licensed IP used in both SOC and discrete versions
# - discrete ones (including all PCI-only controllers)
# - debug/dummy gadget+hcd is last.

depends on ARCH_AT91
help
USBA is the integrated high-speed USB Device controller on
the AT32AP700x, some AT91SAM9 and AT91CAP9 processors from Atmel.
The fifo_mode parameter is used to select endpoint allocation mode.
fifo_mode = 0 is used to let the driver autoconfigure the endpoints.
In this case, for ep1 2 banks are allocated if it works in isochronous
mode and only 1 bank otherwise. For the rest of the endpoints
only 1 bank is allocated.
fifo_mode = 1 is a generic maximum fifo size (1024 bytes) configuration
allowing the usage of ep1 - ep6
fifo_mode = 2 is a generic performance maximum fifo size (1024 bytes)
configuration allowing the usage of ep1 - ep3
fifo_mode = 3 is a balanced performance configuration allowing the
the usage of ep1 - ep8

help
This host controller driver emulates USB, looping all data transfer
requests back to a USB "gadget driver" in the same host. The host
side is the master; the gadget side is the slave. Gadget drivers
can be high, full, or low speed; and they have access to endpoints
like those from NET2280, PXA2xx, or SA1100 hardware.
This may help in some stages of creating a driver to embed in a
Linux device, since it lets you debug several parts of the gadget
driver without its hardware or drivers being involved.
Since such a gadget side driver needs to interoperate with a host
side Linux-USB device driver, this may help to debug both sides
of a USB protocol stack.
Say "y" to link the driver statically, or "m" to build a
dynamically linked module called "dummy_hcd" and force all
