The dwc3 code to get the "peripheral" / "host" / "otg" IRQ first tries
platform_get_irq_byname() and then falls back to the IRQ at index 0 if
the platform_get_irq_byname().
In this case we do not want platform_get_irq_byname() to print an error
on failure, so switch to platform_get_irq_byname_optional() instead which
does not print an error.

Although the algorithms are essentially the same, the old max timeout is
(usec + usec * time of doing readl()), and the new max timeout is just
usec, which is much less than the old one.

The system can hit a deadlock if an xhci adapter breaks while initializing.
The deadlock is between two threads: thread 1 is tearing down the
adapter and is stuck in usb_unlocked_disable_lpm waiting to lock the
hcd->handwidth_mutex. Thread 2 is holding this mutex (while still trying
to add a usb device), but is stuck in xhci_endpoint_reset waiting for a
stop or config command to complete. A reboot is required to resolve.
It turns out when calling xhci_queue_stop_endpoint and
xhci_queue_configure_endpoint in xhci_endpoint_reset, the return code is
not checked for errors. If the timing is right and the adapter dies just
before either of these commands get issued, we hang indefinitely waiting
for a completion on a command that didn't get issued.
This wasn't a problem before the following fix because we didn't send
commands in xhci_endpoint_reset:
commit f5249461b504 ("xhci: Clear the host side toggle manually when
endpoint is soft reset")
With the patch I am submitting, a duration test which breaks adapters
during initialization (and which deadlocks with the standard kernel) runs
without issue.

Early xHCI 1.1 spec did not mention USB 3.1 capable hosts should set
sbrn to 0x31, or that the minor revision is a two digit BCD
containing minor and sub-minor numbers.
This was later clarified in xHCI 1.2.
Some USB 3.1 capable hosts therefore have sbrn set to 0x30, or minor
revision set to 0x1 instead of 0x10.

that return USB3_LPM_DISABLED due to shorter service intervals.

Currently the driver don't support pm_ops. These ops are not necessary
if the supply isn't switchable (always on). This assumptions seems to be
wrong because no one needs a powered hub during suspend-to-ram/disk.

Currently the reset handler was always called to deassert the reset
line because assert the line was done during probe. Now if we want to
support pm by turn of the supply we need to call this routine twice and
the i2c_lock_bus is done twice too. To simplify that we can drop the
state and just do a reset in one go. So a future pm operation don't need
to lock the i2c bus twice.

When R-Car Gen3 USB 2.0 is in Gadget mode, if host is detached an interrupt
will be generated and Suspended state bit is set in interrupt status
register. Interrupt handler will call driver->suspend(composite_suspend)
if suspended state bit is set. composite_suspend will call
ffs_func_suspend which will post FUNCTIONFS_SUSPEND and will be consumed
by user space application via /dev/ep0.
To be able to detect host detach, extend the DVSQ_MASK to cover the
Suspended bit of the DVSQ[2:0] bitfield from the Interrupt Status
Register 0 (INTSTS0) register and perform appropriate action in the
DVST interrupt handler (usbhsg_irq_dev_state).

Salvator-X CN9 port is not recognized and reverse role switch does
not happen. If phone is connected again it does not enumerate.

Commit [1] enabled the possibility of checking the DVST (Device State
Transition) bit of INTSTS0 (Interrupt Status Register 0) and calling
the irq_dev_state() handler if the DVST bit is set. But neither
commit [1] nor commit [2] actually enabled the DVSE (Device State
Transition Interrupt Enable) bit in the INTENB0 (Interrupt Enable
Register 0). As a consequence, irq_dev_state() handler is getting
called as a side effect of other (non-DVSE) interrupts being fired,
which definitely can't be relied upon, if DVST notifications are of
any value.
Why this doesn't hurt is because usbhsg_irq_dev_state() currently
doesn't do much except of a dev_dbg(). Once more work is added to
the handler (e.g. detecting device "Suspended" state and notifying
other USB gadget components about it), enabling DVSE becomes a hard
requirement. Do it in a standalone commit for better visibility and
clear explanation.

Similar to usbhs_status_get_ctrl_stage(), *_get_device_state() is not
supposed to return any error code since its return value is the DVSQ
bitfield of the INTSTS0 register. According to SoC HW manual rev1.00,
every single value of DVSQ[2:0] is valid and none is an error:
----8<----
Device State
000: Powered state
001: Default state
010: Address state
011: Configuration state
1xx: Suspended state
----8<----
Hence, simplify the function body. The motivation behind dropping the
switch/case construct is being able to implement reading the suspended
state. The latter (based on the above DVSQ[2:0] description) doesn't
have a unique value, but is rather a list of states (which makes
switch/case less suitable for reading/validating it):
100: (Suspended) Powered state
101: (Suspended) Default state
110: (Suspended) Address state
111: (Suspended) Configuration state
