4df50f89f5 usb: composite: force gadget to be USB2 for HS only function
If one of functions is not super speed capable, we need force the udc
to be high speed, this is an equivalent implementation of
usb_gadget_udc_set_speed() in kernel but simple, which set the gadget
max_speed to be high speed, so afterwards when start gadget duc can
set the HW to be USB 2.0 mode.

a764c94128 usb: gadget: OS Feature Descriptors support
This is a proting patch from linux kernel: 37a3a533429e
("usb: gadget: OS Feature Descriptors support"), the original commit
log see below:

There is a custom (non-USB IF) extension to the USB standard:

http://msdn.microsoft.com/library/windows/hardware/gg463182

They grant permission to use the specification - there is
"Microsoft OS Descriptor Specification License Agreement"
under the link mentioned above, and its Section 2 "Grant
of License", letter (b) reads:

"Patent license. Microsoft hereby grants to You a nonexclusive,
royalty-free, nontransferable, worldwide license under Microsoft鈥檚
patents embodied solely within the Specification and that are owned
or licensable by Microsoft to make, use, import, offer to sell,
sell and distribute directly or indirectly to Your Licensees Your
Implementation. You may sublicense this patent license to Your
Licensees under the same terms and conditions."

The said extension is maintained by Microsoft for Microsoft.

Yet it is fairly common for various devices to use it, and a
popular proprietary operating system expects devices to provide
"OS descriptors", so Linux-based USB gadgets whishing to be able
to talk to a variety of operating systems should be able to provide
the "OS descriptors".

This patch adds optional support for gadgets whishing to expose
the so called "OS Feature Descriptors", that is "Extended Compatibility ID"
and "Extended Properties".

Hosts which do request "OS descriptors" from gadgets do so during
the enumeration phase and before the configuration is set with
SET_CONFIGURATION. What is more, those hosts never ask for configurations
at indices other than 0. Therefore, gadgets whishing to provide
"OS descriptors" must designate one configuration to be used with
this kind of hosts - this is what os_desc_config is added for in
struct usb_composite_dev. There is an additional advantage to it:
if a gadget provides "OS descriptors" and designates one configuration
to be used with such non-USB-compliant hosts it can invoke
"usb_add_config" in any order because the designated configuration
will be reported to be at index 0 anyway.

This patch also adds handling vendor-specific requests addressed
at device or interface and related to handling "OS descriptors"."

The contents of the string is generated based on the qw_sign

fill cdev->qw_sign with appropriate values and fill cdev->b_vendor_code
with a value of their choice.

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.

31dd8efeb6 usb: composite convert __set_bit to generic_set_bit
Compiling the f_mass_storage driver for an x86 target results in a
compilation error as set_bit and clear_bit are provided by bitops.h

To address that situation we discussed on the list moving to
genetic_set_bit() instead.

Doing a quick grep for similar situations in drivers/usb shows that the
composite device is using __set_bit().

This patch switches over to generic_set_bit to maintain consistency between
the two gadget drivers.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

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.

44bfb43f9a usb: gadget: don't leak configs when unbinding
By the time g_dnl_unbind() is run, cdev->config has been set to NULL,
so the free() there does nothing, and the config struct is leaked.
Equally, struct usb_gadget contains a linked list of config structs, so
the code should iterate over them all and free each one, rather than
freeing one particular config struct.

composite_unbind() already iterates over the list of config structs, and
unlinks each from the linked list. Fix this loop to free() each struct as
it's unlinked and otherwise forgotten.

b41411954d linux/kernel.h: sync min, max, min3, max3 macros with Linux
U-Boot has never cared about the type when we get max/min of two
values, but Linux Kernel does.  This commit gets min, max, min3, max3
macros synced with the kernel introducing type checks.

Many of references of those macros must be fixed to suppress warnings.
We have two options:
 - Use min, max, min3, max3 only when the arguments have the same type
   (or add casts to the arguments)
 - Use min_t/max_t instead with the appropriate type for the first
   argument

f7b4162eb1 usb:composite:fix Provide function data when addressing device with only one interface
This commit fixes problems with some non-standard requests send with
device address instead of interface address (bmRequestType.Receipent field).

This happens with dfu-util (debian version: 0.5), which address non standard
requests (like w_value=0x21 and bRequest=GET_DESCRIPTOR) to device.
Without this fix, the above request is STALLED, and hence causes dfu-util
to assume some standard configuration (packet size = 1024B instead of 4096B)
In turn it displays following errors:
Error obtaining DFU functional descriptor
Warning: Assuming DFU version 1.0
Warning: Transfer size can not be detected
...
Warning: Trying default transfer size 1024

This fix allows passing non-standard request to function setup code, where
it shall be handled.
