e30824f439 usb: s3c-otg: Rename USB_GADGET_S3C_UDC_OTG* to USB_GADGET_DWC2_OTG*
The s3c-otg IP block is in fact a DWC2 OTG one, so finally rename the
config option to make it less misleading. No functional change, just
a mechanical change done using the following script:

  git grep USB_GADGET_S3C_UDC_OTG | cut -d : -f 1 | sort -u | \
  while read line ; do
    sed -i "s/USB_GADGET_S3C_UDC_OTG/USB_GADGET_DWC2_OTG/g" $line ;
  done

6c9e00eebf fastboot: Implement flashing session counter
The fastboot flash command that writes an image to a partition works in
several steps:

1 - Retrieve the maximum size the device can download through the
    "max-download-size" variable

2 - Retrieve the partition type through the "partition-type:%s" variable,
    that indicates whether or not the partition needs to be erased (even
    though the fastboot client has minimal support for that)

3a - If the image is smaller than what the device can handle, send the image
     and flash it.

3b - If the image is larger than what the device can handle, create a
     sparse image, and split it in several chunks that would fit. Send the
     chunk, flash it, repeat until we have no more data to send.

However, in the 3b case, the subsequent transfers have no particular
identifiers, the protocol just assumes that you would resume the writes
where you left it.

While doing so works well, it also means that flashing two subsequent
images on the same partition (for example because the user made a mistake)
would not work withouth flashing another partition or rebooting the board,
which is not really intuitive.

Since we have always the same pattern, we can however maintain a counter
that will be reset every time the client will retrieve max-download-size,
and incremented after each buffer will be flashed, that will allow us to
tell whether we should simply resume the flashing where we were, or start
back at the beginning of the partition.

Using NAKs on empty RX fifo for bulk in transfers is the right choice
for a interrupt driven model, but U-Boot uses polling and expects an
immediate answer if there is no incoming packet. Using ZLP Bulk In Response

As ZLP mode is reset default, there is no need to set it.

This arch does not seem to be supported / used at all in the current

and code that was only referenced by this platform.

Please note that this patch also removes these config options:

- CONFIG_PL011_SERIAL_RLCR
- CONFIG_PL011_SERIAL_FLUSH_ON_INIT

As they only seem to be referenced by u8500 based boards. Without any
such board in the current code, these config option don't make sense
any more. Lets remove them as well.

If someone still wants to use this platform, then please send patches
to re-enable support by adding at least one board that references this

b337b3b2a5 usb: ci_udc: fix emissions of ZLPs
Commit 6a13241635 "ci_udc: Update the ci_udc driver to support bulk
transfers" caused the value of "len" to change without updating subsquent
users of that variable in ci_ep_submit_next_request(). This caused the
code that detects when to emit ZLPs (Zero Length Packets) never to
trigger, which in turn caused host timeouts when a ZLP was required,
which in turn broke tests/dfu/, even despite the assertion in that
commit's description that "These changes are tested for both the DFU and
lthor."

Fix this by modifying the added dtd iteration code not to modify "len",
but rather to keep state in a separate variable. Rename the variables
while we're at it so they describe their purpose better.

44bfb43f9a usb: gadget: don't leak configs when unbinding
By the time g_dnl_unbind() is run, cdev->config has been set to NULL,
so the free() there does nothing, and the config struct is leaked.
Equally, struct usb_gadget contains a linked list of config structs, so
the code should iterate over them all and free each one, rather than
freeing one particular config struct.

composite_unbind() already iterates over the list of config structs, and
unlinks each from the linked list. Fix this loop to free() each struct as
it's unlinked and otherwise forgotten.

    usb: gadget: remove incorrect __init/__exit annotations

    A recent change introduced a link error for the composite
    printer gadget driver:

    `printer_unbind' referenced in section `.ref.data' of drivers/built-in.o: defined in discarded section `.exit.text' of drivers/built-in.o

    Evidently the unbind function should not be marked __exit here,
    because it is called through a callback pointer that is not necessarily
    discarded, __composite_unbind() is indeed called from the error path of
    composite_bind(), which can never work for a built-in driver.

    Looking at the surrounding code, I found the same problem in all other
    composite gadget drivers in both the bind and unbind functions, as
    well as the udc platform driver 'remove' functions. Those will break
    if anyone uses the 'unbind' sysfs attribute to detach a device from a
    built-in driver.

    This patch removes the incorrect annotations from all the gadget
    drivers.

49b4c5c700 usb: ehci: remember init mode
When an EHCI device is registered in device mode, the HW isn't actually
initialized at all, and hence isn't left in a running state. Consequently,
when the device is deregistered, ehci_shutdown() will fail, since the HW
bits it expects to see set in response to its shutdown requests will not
be sent, and the message "EHCI failed to shut down host controller." will
be printed.

Fix ehci-hcd.c to remember whether the device was registered in host or
device mode, and only call ehci_shutdown() for host mode registrations.

c9f8947e66 sunxi: usb-phy: Never power off the usb ports
USB devices are not really designed to get the power bounced off and on
at them. Esp. USB powered harddisks do not like this.

Currently we power off the USB ports both on a "usb reset" and when
booting the kernel, causing the usb-power to bounce off and then back
on again.

This patch removes the powering off calls, fixing the undesirable power
bouncing.

Note this requires some special handling for the OTG port:
1) We must skip the external vbus check if we've already enabled our own
vbus to avoid false positives
2) If on an usb reset we no longer detect that the id-pin is grounded, turn
off vbus as that means an external vbus may be present now
