8038f6d288 usb: gadget: composite: Correct recovery path for register
In case when usb_composite_register() failed once (for whatever reason),
it will fail further even if all conditions are correct. Example:

    => fastboot 2
    Invalid Controller Index
    couldn't find an available UDC
    g_dnl_register: failed!, error: -19
    exit not allowed from main input shell.

    => fastboot 0
    g_dnl_register: failed!, error: -22
    exit not allowed from main input shell.

Despite that 0 is correct index for USB controller, "fastboot 0" command
will fail, because "composite" structure wasn't cleared properly on
previous fail (on "fastboot 2" command).

This patch fixes that erroneous behavior, allowing us to use composite
even after previous failure.

fc18f8d170 dfu: usb: f_dfu: Set deferred call for dfu_flush() function
This patch fixes situation when one would like to write large file into
medium with the file system (fat, ext4, etc).
This change sets file size limitation to the DFU internal buffer size.

Since u-boot is not supporting interrupts and seek on file systems, it
becomes challenging to store large file appropriately.

To reproduce this error - create large file (around 26 MiB) and sent it
to the target board.

Lets examine the flow of USB transactions:

0. DFU uses EP0 with 64B MPS [Max Packet Size]

1. Send file - OUT (PC->target) - dat_26MiB.img is sent with 4096 B transactions

2. Get status - OUT (PC->target) - wait for DFU_STATE_dfuDNLOAD_IDLE (0x05) sent
				   from target board - IN transaction
				   (target->PC)

3. The whole file content is sent to target - OUT (PC->target) with ZLP [Zero
					      Length Packet]

Now the interesting part starts:

4. OUT (PC->target) Setup transaction (request to share DFU state)

5. IN (target->PC) - reply the current DFU state
	- In the UDC driver the req->completion (with dfu_flush) is called
	  after successful IN transfer.
	- The dfu_flush() (called from req->completion callback) saves the
	  whole file at once (u-boot doesn't support seek on fs).
	  Such operation takes considerable time. When the file
	  is large - e.g. 26MiB - this time may be more than 5 seconds.

6. OUT (PC->target) - ZLP, is send in the same time when dfu_flush()
 writes data to eMMC memory.
 The dfu-util application has hard coded timeout on USB transaction
 completion set to 5 seconds (it uses libusb calls).

When the file to store is large (e.g. 26 MiB) the time needed to write it
may excess the dfu-util timeout and following error message will be displayed:
"unable to read DFU status" on the HOST PC console.

This change is supposed to leverage DFU's part responsible for storing files
on file systems. Other DFU operations - i.e. raw/partition write to NAND and
eMMC should work as before.

The only functional change is the error reporting. When dfu_flush() fails
the u-boot prompt will exit with error information and dfu-util application
exits afterwards as well.

- Odroid XU3 (Exynos5433) - test with large file
- Trats (Exynos4210) - test for regression - eMMC, raw,

a4bb9b3636 usb: s3c-otg: Rename s3c_udc_probe() function
The driver is actually for the Designware DWC2 controller.
This patch is the second and final to rename global symbol,
the s3c_udc_probe() function.

The rename is done automatically:
	$ sed -i "s/s3c_udc_probe/dwc2_udc_probe/g" \
		`git grep s3c_udc_probe | cut -d : -f 1`

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
