USB: musb: Use the correct style for SPDX License Identifier

2020-04-16T12:32:47+00:00

This patch corrects the SPDX License Identifier style in
header files related to USB Dual Role (OTG-ready) Controller Drivers.
For C header files Documentation/process/license-rules.rst
mandates C-like comments (opposed to C source files where
C++ style should be used).

Changes made by using a script provided by Joe Perches here:

USB: musb: clean up debugfs file and directory creation

2018-05-31T10:54:21+00:00

When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

Because of this, lots of init functions do not need to have return
values, so this cleans up a lot of unused error handling code that never
could have triggered in the past.

USB: musb: Remove redundant license text

2017-11-07T14:45:01+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.

foundation of tracepoints logging for musb driver to make debug
easier.

usb: musb: remove extern qualifier from musb_debug.h header

2011-12-21T11:21:02+00:00

This change removes confusing extern qualifier, which doesn't have any practical
sense there.

usb: musb: drop unneeded musb_debug trickery

2011-05-13T11:34:04+00:00

We have a generic way of enabling/disabling
different debug messages on a driver called
DYNAMIC_PRINTK. Anyone interested in enabling
just part of the debug messages, please read
the documentation under:

Documentation/dynamic-debug-howto.txt

for information on how to use that great
infrastructure.

usb: fix building musb drivers

2011-05-07T01:16:39+00:00

Commit 3dacdf11 "usb: factor out state_string() on otg drivers"
broke building musb drivers since there is already another
otg_state_string() function in musb drivers, but with different
prototype. Fix musb drivers to use common otg_state_string(), too.

Also provide a nop for otg_state_string() if CONFIG_USB_OTG_UTILS
is not defined.

USB: musb: make DBG() calls actually depend on CONFIG_USB_MUSB_DEBUG

2010-10-22T17:21:52+00:00

Enabling CONFIG_USB_MUSB_DEBUG option causes -DDEBUG to be added to gcc's
command line, however the DBG() macro doesn't depend on DEBUG, so that the
debugging messages get printed regardless of the option, and I don't think
that this was intended. Get rid of otherwise unused xprintk() macro and make
DBG() macro directly call pr_debug() which only results in the actual code
generated if DEBUG is defined.

This change makes musb_hdrc.o ~30% less in size with CONFIG_USB_MUSB_DEBUG
disabled (in host mode).

usb: musb: add debugfs support

2010-05-20T20:21:32+00:00

for now only a simple register dump entry (which can
be rather useful on debugging) and a way to start
test modes.
