25612f23b5 usb: dwc2: Do not mix data toggle for IN and OUT endpoints, check bounds
USB protocol allows for 16 IN and 16 OUT endpoints (USB 2.0 Spec,
8.3.2.2 Endpoint Field). A function may have an EP 1 for both IN and OUT,
so these two should be kept separate. As EPs are either BULK or INTERRUPT
(or ISO), it is fine to have one array per direction for all transfer
types (also see e236519b73).

USB device address is 7 bits, so a bus may have more than 16 devices.
Check the device number, as the DWC2 driver only supports BULK/ISO for
the first 16 devices.

d2ff51b372 usb: dwc2: Add SPLIT INTERRUPT transaction support
CSPLITs for INTERRUPT transactions have to be scheduled in each microframe
following the SSPLIT. INTERRUPT transfers are executed in the next even/
odd microframe depending on the HCCHAR_ODDFRM flag.

As there are no handshakes for INTERRUPT SSPLITs the SSPLIT may have
failed (transport error) without the error being detected by the host
driver. If the last CSPLIT is not received within 4 microframes after the
SSPLIT there was a transaction error and the complete transaction has
to be restarted.

03460cdc3d usb: dwc2: Simplify wait_for_chhltd(), remove ignore_ack
A transfer is completed if the XFERCOMP flag is set, irrespective of the
ACK flag. BULK OUT transfers to some HS devices complete without having
the ACK flag set, which signal the devices has responded with an NYET

56a7bbd741 usb: dwc2: Fix out-of-bounds access, fix chunk size
Fix two errors in transfer len calculation, move loop invariant code out
of loop.

If xfer_len is equal to CONFIG_DWC2_MAX_TRANSFER_SIZE (or slightly
smaller), the xfer_len will be to large, e.g.:
  xfer_len = MAX_TRANSFER_SIZE = 65535
  max packet size = 512
    => num_packets = 128
    => IN xfer_len = 65536

For OUT transactions larger than (65536 - mps) bytes, the xfer_len
determination is quite awkward, it is only correct due to:
- max_packet_size for control/bulk/interrupt is required to be
  power-of-two.
- (CONFIG_DWC2_MAX_TRANSFER_SIZE + 1) % max-packet-size is zero
  for all allowed (2^3 ... 2^9) packet sizes

As the max xfer len is loop invariant, it can be moved out of the loop.

ums 0 mmc 0,0.1,0.2

... which would export LUNs for eMMC 0's user data, boot0, and boot1 HW
partitions. This is useful since it allows the host access to everything
on the eMMC without having to somehow stop the ums command from executing
and restart it with different parameters.

ac3abf0b7d usb: musb: Fix hub port setting for SPLIT transactions
The ifdef'ed Linux kernel code uses the 1 based port number, whereas U-Boot
puts a 0 based port number into the register. The reason the 0 based port
number apparently works can probably be taken from the USB 2.0 spec:

8.4.2.2 Start-Split Transaction Token
... The host must correctly set the port field for single and multiple TT
hub implementations. A single TT hub implementation *may ignore* the port
field.

Actually, as far as I understand, a multi TT hub defaults to single TT
(bAlternateSetting: 0) until switched via SetInterface, so even "port 42"
would work.

The change was verified by hardcoding the port number to a wrong value,
SPLIT transactions kept working (although using a DWC2 instead of MUSB).
Tested hubs are the RPi onboard SMC9514 and an external "05e3:0608
Genesys Logic, Inc. USB-2.0 4-Port HUB". The former is a multi TT hub,
the latter single TT only.

With the old order of initialization the hcor pointer has been setup to
the same address as Exynos EHCI base address (0x12110000 instead of
0x12110010).
Such behaviour was caused by reading value of 0 instead of 0x10 from EHCI
HCCPBASE register without doing proper clock initialization before.

To fix this problem hcor initialization has been moved after USB PHY setup.
Now ehci_readl(&ctx->hcd->cr_capbase) returns correct value.

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.

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.

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

    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.

4e9838c102 dm: Use dev_get_addr() where possible
This is a convenient way for a driver to get the hardware address of a
device, when regmap or syscon are not being used. Change existing callers
to use it as an example to others.

7806b75a05 sunxi: musb: Drop no longer accurate comment in Kconfig help text
Drop the no longer accurate part of the USB_MUSB_SUNXI Kconfig help text,
since the musb-host code now supports the device-model, ehci and musb in
host mode can both be enabled at the same time without issues.
