93fb9127cb usb: renesas_usbhs: Don't disable the pipe if Control write status stage
This patch fixes an issue that sometimes this controller is not able
to complete the Control write status stage.

This driver should enable DCPCTR.CCPL and PID_BUF to complete the status
stage. However, if this driver detects the ctrl_stage interruption first
before the control write data is received, this driver will clear the
PID_BUF wrongly in the usbhsf_pio_try_pop(). To avoid this issue, this
patch doesn't clear the PID_BUF in the usbhsf_pio_try_pop().
(Since also the privious code doesn't disable the PID_BUF after a control
 transfer was finished, this patch doesn't have any side efforts.)

e73d42f15f usb: renesas_usbhs: Fix fifo unclear in usbhsf_prepare_pop
This patch fixes an issue for control write. When usbhsf_prepare_pop()
is called after this driver called a gadget setup function, this controller
doesn't receive the control write data. So, this patch adds a code to clear
the fifo for control write in usbhsf_prepare_pop().

49a79d8b0a usb: gadget: ffs: fix: Always call ffs_closed() in ffs_data_clear()
Originally FFS_FL_CALL_CLOSED_CALLBACK flag has been used to
indicate if we should call ffs_closed_callback().

Commit 4b187fceec ("usb: gadget: FunctionFS: add devices
management code") changed its semantic to indicate if we should
call ffs_closed() function which does a little bit more.

This situation leads to:

in some cases (reproduction path below). This commit get back
semantic of that flag and ensures that ffs_closed() is called
always when needed but ffs_closed_callback() is called only
if this flag is set.

Reproduction path:
Compile kernel without any UDC driver or bound some gadget
to existing one and then:

$ modprobe g_ffs
$ mount none -t functionfs mount_point
$ ffs-example mount_point

This will fail with -ENODEV as there is no udc.

$ ffs-example mount_point

This will fail with -EBUSY because ffs_data has not been
properly cleaned up.

c94e289f19 usb: gadget: remove incorrect __init/__exit annotations
A recent change introduced a link error for the composite
printer gadget driver:

`printer_unbind' referenced in section `.ref.data' of drivers/built-in.o: defined in discarded section `.exit.text' of drivers/built-in.o

Evidently the unbind function should not be marked __exit here,
because it is called through a callback pointer that is not necessarily
discarded, __composite_unbind() is indeed called from the error path of
composite_bind(), which can never work for a built-in driver.

Looking at the surrounding code, I found the same problem in all other
composite gadget drivers in both the bind and unbind functions, as
well as the udc platform driver 'remove' functions. Those will break
if anyone uses the 'unbind' sysfs attribute to detach a device from a
built-in driver.

This patch removes the incorrect annotations from all the gadget
drivers.

197d0bdf8b usb: phy: isp1301: work around tps65010 dependency
The isp1301-omap driver contains special hooks for the TPS65010
power management controller. It provides its own 'tps65010_set_vbus_draw'
wrapper in case that driver is not enabled through Kconfig, but
fails to handle the case where isp1301-omap is built-in but TPS65010
is a loadable module, which currently results in a link error:

drivers/built-in.o: In function `isp1301_set_power':
:(.text+0x14e188): undefined reference to `tps65010_set_vbus_draw'

This is a workaround to use the same trick as before also when
tps65010 is a module. Doing a proper fix would require much larger
changes to the driver that is not really worth it when the usb-phy
drivers are going to eventually get replaced with generic-phy
drivers.

3e9d3d2efc usb: gadget: serial: fix re-ordering of tx data
When a single thread is sending out data over the gadget serial port,
gs_start_tx() will be called both from the sender context and from the
write completion. Since the port lock is released before the packet is
queued, the order in which the URBs are submitted is not guaranteed.
E.g.

  sending thread                      completion (interrupt)

  gs_write()
    LOCK
                                      gs_write_complete()
                                        LOCK (wait)
    gs_start_tx()
      req1 = list_entry(pool->next)
      UNLOCK
                                        LOCK (acquired)
                                        gs_start_tx()
                                          req2 = list_entry(pool->next)
                                          UNLOCK
                                          usb_ep_queue(req2)
      usb_ep_queue(req1)

I.e., req2 is submitted before req1 but it contains the data that
comes after req1.

To reproduce, use SMP with sending thread and completion pinned to
different CPUs, or use PREEMPT_RT, and add the following delay just
before the call to usb_ep_queue():

		if (port->write_started > 0 && !list_empty(pool))
			udelay(1000);

To work around this problem, make sure that only one thread is running
through the gs_start_tx() loop with an extra flag write_busy. Since
gs_start_tx() is always called with the port lock held, no further
synchronisation is needed. The original caller will continue through
the loop when the request was successfully submitted.

Most of kernel code assume that interface array in
struct usb_configuration is NULL terminated.

When gadget is composed with configfs configuration
structure may be reused for different functions set.

This bug happens because purge_configs_funcs() sets
only next_interface_id to 0. Interface array still
contains pointers to already freed interfaces. If in
second try we add less interfaces than earlier we
may access unallocated memory when trying to get
interface descriptors.

9ac8928e6a target: simplify the target template registration API
Instead of calling target_fabric_configfs_init() +
target_fabric_configfs_register() / target_fabric_configfs_deregister()
target_fabric_configfs_free() from every target driver, rewrite the API
so that we have simple register/unregister functions that operate on
a const operations vector.

This patch also fixes a memory leak in several target drivers. Several
target drivers namely called target_fabric_configfs_deregister()
without calling target_fabric_configfs_free().

A large part of this patch is based on earlier changes from
Bart Van Assche <bart.vanassche@sandisk.com>.

(v2: Add a new TF_CIT_SETUP_DRV macro so that the core configfs code
can declare attributes as either core only or for drivers)

eeee78cf77 Some clean ups and small fixes, but the biggest change is the addition
of the TRACE_DEFINE_ENUM() macro that can be used by tracepoints.
 
 Tracepoints have helper functions for the TP_printk() called
 __print_symbolic() and __print_flags() that lets a numeric number be
 displayed as a a human comprehensible text. What is placed in the
 TP_printk() is also shown in the tracepoint format file such that
 user space tools like perf and trace-cmd can parse the binary data
 and express the values too. Unfortunately, the way the TRACE_EVENT()
 macro works, anything placed in the TP_printk() will be shown pretty
 much exactly as is. The problem arises when enums are used. That's
 because unlike macros, enums will not be changed into their values
 by the C pre-processor. Thus, the enum string is exported to the
 format file, and this makes it useless for user space tools.
 
 The TRACE_DEFINE_ENUM() solves this by converting the enum strings
 in the TP_printk() format into their number, and that is what is
 shown to user space. For example, the tracepoint tlb_flush currently
 has this in its format file:
 
      __print_symbolic(REC->reason,
         { TLB_FLUSH_ON_TASK_SWITCH, "flush on task switch" },
         { TLB_REMOTE_SHOOTDOWN, "remote shootdown" },
         { TLB_LOCAL_SHOOTDOWN, "local shootdown" },
         { TLB_LOCAL_MM_SHOOTDOWN, "local mm shootdown" })
 
 After adding:
 
      TRACE_DEFINE_ENUM(TLB_FLUSH_ON_TASK_SWITCH);
      TRACE_DEFINE_ENUM(TLB_REMOTE_SHOOTDOWN);
      TRACE_DEFINE_ENUM(TLB_LOCAL_SHOOTDOWN);
      TRACE_DEFINE_ENUM(TLB_LOCAL_MM_SHOOTDOWN);
 
 Its format file will contain this:
 
      __print_symbolic(REC->reason,
         { 0, "flush on task switch" },
         { 1, "remote shootdown" },
         { 2, "local shootdown" },
         { 3, "local mm shootdown" })

  __print_symbolic() and __print_flags() that lets a numeric number be
  displayed as a a human comprehensible text.  What is placed in the
  TP_printk() is also shown in the tracepoint format file such that user
  space tools like perf and trace-cmd can parse the binary data and
  express the values too.  Unfortunately, the way the TRACE_EVENT()
  macro works, anything placed in the TP_printk() will be shown pretty
  much exactly as is.  The problem arises when enums are used.  That's
  because unlike macros, enums will not be changed into their values by
  the C pre-processor.  Thus, the enum string is exported to the format
  file, and this makes it useless for user space tools.

  The TRACE_DEFINE_ENUM() solves this by converting the enum strings in
  the TP_printk() format into their number, and that is what is shown to
  user space.  For example, the tracepoint tlb_flush currently has this
  in its format file:

     __print_symbolic(REC->reason,
        { TLB_FLUSH_ON_TASK_SWITCH, "flush on task switch" },
        { TLB_REMOTE_SHOOTDOWN, "remote shootdown" },
        { TLB_LOCAL_SHOOTDOWN, "local shootdown" },
        { TLB_LOCAL_MM_SHOOTDOWN, "local mm shootdown" })

  After adding:

     TRACE_DEFINE_ENUM(TLB_FLUSH_ON_TASK_SWITCH);
     TRACE_DEFINE_ENUM(TLB_REMOTE_SHOOTDOWN);
     TRACE_DEFINE_ENUM(TLB_LOCAL_SHOOTDOWN);
     TRACE_DEFINE_ENUM(TLB_LOCAL_MM_SHOOTDOWN);

  Its format file will contain this:

     __print_symbolic(REC->reason,
        { 0, "flush on task switch" },
        { 1, "remote shootdown" },
        { 2, "local shootdown" },
        { 3, "local mm shootdown" })"

9b6567e19b usb: chipidea: udc: bypass pullup DP when gadget connect in OTG fsm mode
By pass pullup DP in OTG fsm mode when do gadget connect, to let it handled

This patch can fix the problem you found with my HNP polling patchset after
below 3 patches introduced:
467a78c usb: chipidea: udc: apply new usb_udc_vbus_handler interface
628ef0d usb: udc: add usb_udc_vbus_handler
dfea9c9 usb: udc: store usb_udc pointer in struct usb_gadget

Problem:
- Connect USB cable and MicroAB cable between two boards
- Boot up two boards
- load g_mass_storage at B-device side, the enumeration will success,
and A will see a usb mass-storage device
- load g_mass_storage at A-device side, the problem has occurred, the
connection will be lost at the beginning, then connect again.

This patch is based on
