6ca98bc284 USB: serial: Remove redundant license text
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.

5fd54ace47 USB: add SPDX identifiers to all remaining files in drivers/usb/
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.

aa1f3bb567 USB: core: move existing SPDX tags to top of the file
To match the rest of the kernel, the SPDX tags for the drivers/usb/core/
files are moved to the first line of the file.  This makes it more
obvious the tag is present as well as making it match the other 12k
files in the tree with this location.

It also uses // to match the "expected style" as well.

20ef800bab usb: mtu3: fix dma_addr_t printk output again
The support for 36-bit addresses originally came with an incorrect
printk format for dma addresses. Felipe changed the format string it
while applying, but the result was still incorrect, since we now have
to pass a pointer to the address instead of the integer value:

drivers/usb/mtu3/mtu3_qmu.c: In function 'mtu3_prepare_tx_gpd':
drivers/usb/mtu3/mtu3_qmu.c:261:25: error: format '%p' expects argument of type 'void *', but argument 7 has type 'dma_addr_t {aka unsigned int}' [-Werror=format=]
drivers/usb/mtu3/mtu3_qmu.c: In function 'mtu3_prepare_rx_gpd':
drivers/usb/mtu3/mtu3_qmu.c:300:25: error: format '%p' expects argument of type 'void *', but argument 7 has type 'dma_addr_t {aka unsigned int}' [-Werror=format=]

This fixes the printk argument accordingly.

9506b146fa usb: xhci: tegra: use time64_t for printing timestamp
The time_t type and time_to_tm() function are deprecated because
of y2038 problems. In this driver, they are used to pretty-print
the timestamp of the firmware build. This is fine as long as
we don't get a firmware build past 2038.

Converting to time64_t and time64_to_tm() avoids the deprecated
interfaces and works until 2106, when the firmware-defined
data structure overflows.

69a0c69aab usb: usb251xb: Use GPIO descriptor consumer interface
The driver used to be developed with legacy GPIO API support. It's
better to use descriptor-based interface for several reasons. First
of all the legacy API doesn't support the ACTIVE_LOW/HIGH flag of dts
nodes, which is essential since different hardware may have different
GPIOs connectivity including the logical value inversion. Secondly,
by requesting the reset GPIO descriptor the driver prevent the other
applications from changing its value. And last but not least the
legacy GPIO interface should be avoided in the new code due to it
obsolescence.

Battery charging settings are supported by USB251xb hubs only.
USB2517i isn't one of them. So we need to reflect it within the
device-specific data structure. The driver doesn't support dts
property changing this setting, but instead defaults it with zero.
So the flag isn't used anywhere in the driver, but still can be helpful
in future, when necessity of the corresponding dts setting arises.

a8a5267756 usb: usb251xb: Update usb251xb bindings
Since hub usb2517 is going to be supported by the usb251xb driver,
the bindings need to be properly updated. Particularly:
- add "microchip,usb2517" and "microchip,usb2517i" compatible strings.
- add "boolean" description to all the properties, which really accept
a boolean value including a new one "led-{usb,speed}-mode".
- move reset-gpios property to the optional section. It isn't
defined as required in the code and shouldn't be required at all, since
hardware may handle reset pins by itself.
- add new led-{usb,speed}-mode mode property. USB2517 device supports
two LED modes: USB mode and speed (default) indication mode. The last one
can be switched on by this property.
- add {bp,sp}-max-{total,removable}-current-microamp property measured in
microamp. It hasn't been defined as property before. Since the limitation
specified by these parameters is hardware specific it needs to be defined
in dts.

74fef19f66 usb: gadget: zero: Convert timers to use timer_setup()
In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly. Adds a static tracking variable to
match the timer global.

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly. This rearranges the arrays of timers
to minimize the need for a pointer back to the main structure.

32bf9fd50f usb-storage: make use of srb local variable
Commit 8b52291a07 ("usb-storage: fix deadlock involving host lock
and scsi_done") added a local variable to usb_stor_control_thread() in
the usb-storage driver.  This local variable holds the value of
us->srb, for use after the host lock has been released.

But as long as we have the value in a local variable, we may as well
use it instead of dereferencing the us pointer all over the place.
This patch makes no functional change; it just makes the code a little
shorter and a little neater.

b6565a07ca usb: wusbcore: Use put_unaligned_le32
Use put_unaligned_le32 rather than using byte ordering function and
memcpy which makes code clear.
Also, add the header file where it is declared.

Done using Coccinelle and semantic patch used is :

@ rule1 @
identifier tmp; expression ptr,x; type T;
@@

- tmp = cpu_to_le32(x);

  <+... when != tmp
- memcpy(ptr, (T)&tmp, ...);
+ put_unaligned_le32(x,ptr);
  ...+>

@ depends on rule1 @
type j; identifier tmp;
@@

- j tmp;
  ...when != tmp
