1c1464c2b1 usb: ether: call _usb_eth_halt() if initialization fails
If the host does not respond in time, the initialization fails. However
the usb ether driver will still be registered. This will make
usb_gadget_probe_driver() fail the next time the initialization is
attempted because it cannot find an available UDC.

Fixing this by calling _usb_eth_halt() when the init fails.

No mainline board enables CONFIG_MCAST_TFTP and there have been
compilation issues with the code for some time. Additionally, it has a
potential buffer underrun issue (reported as a side note in

801f1fa442 dm: usb: udc: Use SEQ_ALIAS to index the USB gadget ports
dfu, fastbot and other usb gadget commands take the USB port index as a
parameter. Currently this index is assigned in the order of the driver
bindings.
Changing this behavior using the SEQ_ALIAS feature. This option assign to
the device a SEQ number based on its alias (if it exists)

To use it we must set the DM_UC_FLAG_SEQ_ALIAS flag and follow the existing
naming convention: use "usb" for the name of the gadget UCLASS_DRIVER
(same as for the UCLASS_USB).

If no alias is provided, then the index falls back to the order in which
the bindings took place.

771e76515e usb: composite: Fix max packet size for USB3.0
For USB3.0, the max packetsize for GET_DESCRIPTOR should be
sent as exponent value for 2. This means for 512, max packet
size should be filled with 9(2^9=512). Also, fill the USB
version field with 3.0 if speed is negotiated to Superspeed.
This fixes the issue of DFU gadget download failure with
superspeed. Without this patch, the max packet size is
overflowed to zero as the bMaxPacketsize is of u8 and hence
host is not able to detect this device.

7d98dbcc3d usb: musb-new: Add support for DM_USB
Enable DM for USB peripheral in the musb-new driver.
Also make sure that the driver can be used in the SPL.
This implies that:
* the driver must work with and without the OF_CONTROL option. That
in turn, implies that the platform data can be passed in a struct
ti_musb_platdata or be read from the dtb
* usb.o is linked in the SPL if host support is enabled

Another change is that the driver does not fail to bind (and stop the boot
process) if one of the child driver does not bind. Reporting the error is
enough. This kind of error would appear if the port is configured in the
DTS but the driver is not activated in the config.

16ecb295b3 usb: Don't enable CONFIG_SPL_DM_USB for non-DM SPL
When CONFIG_SPL_DM_USB was added, it was added defaulted on without
protection to ensure it didn't get set for non-DM SPL builds.

This leads to unexpected and confusing failures when building a DM based
U-Boot but with a non-DM SPL, as the defconfig is unlikely to have
CONFIG_SPL_DM_USB actively disabled.

Tweak the Kconfig to not enable this setting unless CONFIG_SPL_DM is set.

1a35526e1d usb: musb-new: omap2430: Enable DM_USB and OF support
With upcoming changes that require CONFIG_BLK, this broke
USB Mass Storage on the OMAP3 boards because if CONFIG_BLK is
enabled, it assumes that DM_USB is enabled, but it wasn't yet
available on omap3 and omap4 boards.

This patch converts the OMAP2430 MUSB glue to support DM_USB and
extracts the necessary information based on the device tree.

It's based on the ti-musb driver, but there are enough significant
differences in both the architecture and device tree entires between
am33xx and OMAP3/OMAP4, that I think it makes sense to continue to
keep the separate.

Per doc/driver-model/usb-info.txt, the USB gadget stuff hasn't
migrated to DM_USB yet, so this only supports USB Host for now.

Users wanting USB Gadgets will need to disable DM_USB and leave
it the old way for now.

11758a56ab usb: rockchip: be quiet on serial port while transferring data
While downloading or uploading megabytes of data we had thousands of
printf in console like:

transfer 0x10000 bytes done
OR
Uploading 0x1000 bytes

This because transfers are chunked and there is no way on target
side to know the overall transfer size (to print one string per
overall transfer).

All these prints on serial console do slow down significantly the
transfer and does not offer a significant information to the
developer: rkdeveloptool and Rockchip original tool do use small
chunks read/writes on big transfers. This allows on workstation
to print percentage of transfer complete and as well offers to
developer the information about: transfer is running OK.
On error, either the percentage will stop or an error will be shown
on workstation console.

cad66e324d usb: rockchip: fix command failed on host side due to missing data
Two consecutive rockusb_tx_write without waiting for request complete
do results in transfer reset of first request and thus no or incomplete
data transfer. This because rockusb_tx_write do use just one USB request
to keep serialization.

So calls like:
rockusb_tx_write_str(emmc_id);
rockusb_tx_write_csw(cbw->tag, cbw->data_transfer_length, CSW_GOOD);

was succeeding only when DEBUG was defined because the time spent
printing debug info was enough for transfer to complete.

This patch fixes the issue adding a simple request complete handler
called rockusb_tx_write_csw to be set as complete handler of in_req
when sending back simple payload + CSW replies to commands.

This new handler will always send CSW_GOOD replies because in case
of error the command callback itself must send back an error CSW as
unique reply to command.

This patch fixes execution of:
$ rkdeveloptool rfi
when DEBUG is not defined.

9c22aec410 usb: sunxi: Use proper reg_mask for clock gate, reset
Masking clock gate, reset register bits based on the
probed controller is proper only due to the assumption
that masking should start with 0 even thought the controller
has separate PHY or shared between OTG.

unfortunately these are fixed due to lack of separate
clock, reset drivers.

Say for example EHCI1 - EHCI3 in the datasheet (EHCI0 is for the OTG)
so we need to start reg_mask 0 - 2.

This patch calculated the mask, based on the register base
so that we can get the proper bits to set with respect to
probed controller.

We even do this masking by using PHY index specifier from dt,
but dev_read_addr_size is failing for 64-bit boards.

When the host attempts to receive a packet, but a packet has not

(Bulk-In Empty Response) to NAK. Unfortunately, this hangs
the USB controller and requires the USB controller to
be reset.

The fix proposed is to have the lan78xx controller respond

Add drivers/fastboot/fb_common.c, where fastboot_okay/fail are implemented
so we can call them from a non-USB implementation.

Introduce fastboot_response which takes varargs parameters so we can
use it to generate formatted response strings. Refactor fastboot_okay/fail
to use it.

c4ded03ef6 fastboot: Refactor fastboot_okay/fail to take response
Add the response string as a parameter to fastboot_okay/fail, instead
of modifying a global, to match the contract expected by the AOSP
U-Boot code.

afa314d3a3 rockchip: xhci: remove DTS parsing for PHY (which is unused)
The xhci wrapper-driver for Rockchip searches the DTS to find its
child node compatbile with 'rockchip,rk3399-usb3-phy' to retrieve the
base-address of the PHY.  However, this is currently broken (and
always has been), returning NULL.  However, the (wrongly) retrieved
base-address is never used.

We thus remove this code for now.

e40406603f usb: xhci: Handle endianness in xhci_set_configuration()
In xhci_set_configuration(), 'Context Entries' field in the slot
context was cleared with mask LAST_CTX_MASK, but it should have
taken the endianness into consideration.

eaaefb066c usb: xhci: Fix config fail of FS hub behind a HS hub with MTT
If a full speed hub connects to a high speed hub which supports MTT,
the MTT field of its slot context will be set to 1 when xHCI driver
setups an xHCI virtual device in xhci_setup_addressable_virt_dev().
Once usb core fetch its hub descriptor, and need to update the xHC's
internal data structures for the device, the HUB field of its slot
context will be set to 1 too, meanwhile MTT is also set before, this
will cause configure endpoint command fail. In the case, we should
clear MTT to 0 for full speed hub according to section 6.2.2.

This keeps in sync with Linux kernel commit:
  096b110: usb: xhci: fix config fail of FS hub behind a HS hub with MTT
