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

It happens when enable debug log, if set_alt() returns
USB_GADGET_DELAYED_STATUS and usb_composite_setup_continue()
is called before increasing count of @delayed_status,
so fix it by using spinlock of @cdev->lock.

Lookup and associate serial-port device-tree nodes given a parent
USB-interface node during probe.
Note that a serial-port node must be named "serial" and have a "reg"
property so that ports on multi-port interfaces can be distinguished.

Add a hub device and two USB devices, of which one has a combined node.
Note that we need to represent the serial ports as well -- consider
devices with multiple ports per interface; which one should serdev
use? Sibling devices can also be described this way (e.g. gpio@0), and
would need to use th
These are some patches I've been using to test out using serdev with USB
serial. Adding device-tree support to USB serial is really a
separate matter and could be merged before the remaining issues related
to hotplug are addressed for serdev.
Note that this has been a low-intensity on-going effort
Enable serdev support by using the serdev opt-in tty-port registration
helpers.

SIMCOM are reusing a single device ID for many (all of their?)
different modems, based on different chipsets and firmwares. Newer
Qualcomm chipset generations require setting DTR to wake the QMI

As the amount of available ports varies by the kernels build
configuration. To remove the limitation of the fixed 128 ports
we allocate the amount of idevs by using the number we get
