usb: host: Replace empty define with do while

2018-09-28T13:03:37+00:00

It's dangerous to use empty code define.
Furthermore it lead to the following warning:
"suggest braces around empty body in an « else » statement"

So let's replace emptyness by "do {} while(0)"

Furthermore, as suggested by Joe Perches, rename the macro to INCR.

USB: host: ehci: Remove redundant license text

2017-11-07T14:45:02+00:00

Now that the SPDX tag is in all USB files, that identifies the license
in a specific and legally-defined manner.  So the extra GPL text wording
can be removed as it is no longer needed at all.

This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text.  And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.

No copyright headers or other non-license-description text was removed.

USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02+00:00

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Update the drivers/usb/ and include/linux/usb* files with the correct
SPDX license identifier based on the license text in the file itself.
The SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.

This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

fsl/usb: Workarourd for USB erratum-A005697

2016-12-05T14:13:58+00:00

The EHCI specification states the following in the SUSP bit description:
In the Suspend state, the port is sensitive to resume detection.
Note that the bit status does not change until the port is suspended and
that there may be a delay in suspending a port if there is a transaction
currently in progress on the USB.

However, in NXP USBDR controller, the PORTSCx[SUSP] bit changes immediately
when the application sets it and not when the port is actually suspended.

So the application must wait for at least 10 milliseconds after a port
indicates that it is suspended, to make sure this port has entered
suspended state before initiating this port resume using the Force Port
Resume bit. This bit is for NXP controller, not EHCI compatible.

usb: host: unhide suspend/resume declarations

2016-03-04T04:37:41+00:00

There is no need to hide function declarations, and making
these visible to the SoC specific host drivers lets us
use __maybe_unused and IS_ENABLED() checks to control
their use, rather than having to use #ifdef to hide all
callers.

usb: ehci: remove old stub_debug_files definition

2016-02-03T21:44:05+00:00

This patch removes the local STUB_DEBUG_FILES debugging
definition. STUB_DEBUG_FILES was used only in ehci-hcd, whereas
CONFIG_DYNAMIC_DEBUG is used all over the kernel.
