When receiving a disconnect event from the UDC, the mass storage
function driver currently runs the handle_exception() routine
asynchronously. For UDCs that support runtime PM, there is a
possibility the UDC is already suspended by the time the
do_set_interface() is executed. This can lead to HW register access
while the UDC is already suspended.

The new wrapper functions for usb_control_msg() can accept data from

usb_control_msg_recv() is a new wrapper function for usb_control_msg()
that has error checks for short reads. This function also accepts data
buffer on stack. Hence use this function to simplify error handling for
short reads. Short reads will now get reported as -EREMOTEIO with no
indication of how short the transfer was.

The second argument was only used by the USB gadget code, yet everyone
pays the overhead of passing a zero to be passed into aio, where it
ends up being part of the aio res2 value.
Now that everybody is passing in zero, kill off the extra argument.

The USB gadget code is the only code that every tried to utilize the
2nd argument of the aio completions, but there are strong suspicions
that it was never actually used by anything on the userspace side.
Out of the 3 cases that touch it, two of them just pass in the same
as res, and the last one passes in error/transfer in res like any
other normal use case.
Remove the 2nd argument, pass 0 like the rest of the in-kernel users
of kiocb based IO.

Currently the dwc2 doesn't fill in the 'otg_caps' of usb_gadget structure.
When registering a gadget device (e.g. via configfs), the
usb_otg_descriptor_init() checks the 'otg_caps' and 'otg_rev'. It defaults
to HNP and SRP bmAttributes if unspecified. There may be a mismatch with
what's being set in dwc2 params structure. This result in the descriptors
to be miss-configured in this case.
So replace 'otg_cap' bit field by 'otg_caps' structure, so hnp, srp and
otg_rev' can be configured directly in the params.
It's then provided to the gadget struct. These parameters can be tuned
for each platform. In case it's not set, it will default to current
behavior.
Also add option to setup these from the device tree by calling
of_usb_update_otg_caps(). This provides support for standard properties
such as "otg-rev", "hnp-disable" and "srp-disable" (see usb-drd.yaml).

Some functions may dynamically enable and disable their endpoints
regularly throughout their operation, particularly when Set Interface
is employed to switch between Alternate Settings. For instance the
UAC2 function has its respective endpoints for playback & capture
associated with AltSetting 1, in which case those endpoints would not
get enabled until the host activates the AltSetting. And they
conversely become disabled when the interfaces' AltSetting 0 is
chosen.
With the DWC3 FIFO resizing algorithm recently added, every
usb_ep_enable() call results in a call to resize that EP's TXFIFO,
but if the same endpoint is enabled again and again, this incorrectly
leads to FIFO RAM allocation exhaustion as the mechanism did not
account for the possibility that endpoints can be re-enabled many
times.
Example log splat:
dwc3 a600000.dwc3: Fifosize(3717) > RAM size(3462) ep3in depth:217973127
configfs-gadget gadget: u_audio_start_capture:521 Error!
dwc3 a600000.dwc3: request 000000000be13e18 was not queued to ep3in
Add another bit DWC3_EP_TXFIFO_RESIZED to dep->flags to keep track of
whether an EP had already been resized in the current configuration.
If so, bail out of dwc3_gadget_resize_tx_fifos() to avoid the
calculation error resulting from accumulating the EP's FIFO depth
repeatedly. This flag is retained across multiple ep_disable() and
ep_enable() calls and is cleared when GTXFIFOSIZn is reset in
dwc3_gadget_clear_tx_fifos() upon receiving the next Set Config.

Instead of maintaining a single-linked list of devices that must be
searched linearly in .remove() just use spi_set_drvdata() to remember the
link between the spi device and the driver struct. Then the global list
and the next member can be dropped.
This simplifies the driver, reduces the memory footprint and the time to
search the list. Also it makes obvious that there is always a corresponding
driver struct for a given device in .remove(), so the error path for
!max3421_hcd can be dropped, too.
As a side effect this fixes a data inconsistency when .probe() races with
itself for a second max3421 device in manipulating max3421_hcd_list. A
similar race is fixed in .remove(), too.

If dwc2_drd_role_sw_set is called before udc_start (it is the case if the

While going into S3 or S4 suspend, an OHCI host controller can
generate interrupt requests if the INTR_SF enable flag is set. The
interrupt handler routine isn't prepared for this and it doesn't turn
off the flag, causing an interrupt storm.
To fix this problem, make ohci_rh_suspend() always disable INTR_SF
interrupts after processing the done list and the ED unlinks but
before the controller goes into the suspended (non-UsbOperational)
state. There's no reason to leave the flag enabled, since a
suspended controller doesn't generate Start-of-Frame packets.
