Moiz Sonasath dc8738d95b usb: otg: twl6030-usb: Fix twl writes
There were mistakes in writing to few twl
registers. There was interchange in the
parameters being passed to twl6030_writeb().

Shinya Kuribayashi 7cbb062ade USB: gpio_vbus: wakeup support on GPIO VBUS interrupts
We'd like to see the system waking up from the system-wide suspend
when it gets plugged-in, or the USB cable is pulled out.

Also makes it configurable via platform data 'wakeup'.

Shinya Kuribayashi c8240c1b81 USB: gpio_vbus: handle IRQ flags properly
Currently, 'res->flags' handlings are wrong in three respects:
* the driver _modifies_ the contents of platform data
* res->flags is set up, but not used anywhere in the driver
* request_irq() always takes VBUS_IRQ_FLAGS, regardless of refs->flags

This patch tries to fix this with a policy: If a platform IRQ resource
is available, give preference to its IRQ flag(s) over a default one
(VBUS_IRQ_FLAGS).

IRQF_SAMPLE_RANDOM has been scheduled for removal for years (it was
scheduled by July 2009, but not yet remvoed).

I'm not sure when it's going to take place, but would be better to
remove it now.  Thanks for scripts/checkpatch secretary.

Shinya Kuribayashi 123bbceebe USB: gpio_vbus: use cached IRQ number for consistency with the probed one
gpio_vbus is designed to be able to get an IRQ number for VBUS change
interrupt either (1) through platform_get_resource(IORESOURCE_IRQ) or
(2) by processing gpio_to_irq(pdata->gpio_vbus), in probe() function.

On the other hand, gpio_vbus_set_peripheral() and gpio_vbus_remove()
are always doing gpio_to_irq(pdata->gpio_vbus) to get an IRQ number.

This is not just inconsistent, but also broken.  There is no guarantee
that an IRQ number obtained by platform_get_resource() is equal to
gpio_to_irq(pdata->gpio_vbus).

Cache an IRQ number in probe() function, and use it where necessary.

The flag of IRQF_ONESHOT should be passed to request_threaded_irq,
otherwise the following failure message will be dumped because
hardware handler is defined as NULL:

!ONESHOT for irq 356

Shinya Kuribayashi e44694e858 USB: gpio_vbus: avoid consecutive vbus_session calls with the same "is_active"
Basically, ->vbus_session() calls should be served when VBUS session
starts and ends (it's not whenever transciever drivers detect VBUS
_changes_).  Otherwise, if UDC gadget drivers don't want for some
reason ->vbus_session() calls with the same "is_active" value, either
OTG or UDC drivers need to have some protection handlings.

Also, on platforms using this 'gpio_vbus' driver, the driver is only
allowed to check whether VBUS is applied.  There is no kernel-standard
way prepared for UDC gadget drivers to do that.

With this in mind, gpio_vbus should try to prevent unnecessary
consecutive vbus_session calls being served with the same "in_active"
value.

Shinya Kuribayashi 934ccec4da USB: gpio_vbus: provide an appropriate debounce interval
In commit c2344f13b5 (USB: gpio_vbus:
add delayed vbus_session calls, 2009-01-24), usb_gadget_vbus_connect()
and ...disconnect() were extracted from the interrupt handler, so to
allow vbus_session handlers to deal with msleep() calls.

This patch takes the approach one step further.

USB2.0 specification (7.1.7.3 Connect and Disconnect Signaling) says
that the USB system software (shall) provide a debounce interval with
a minimum duration of 100 ms, which ensures that the electrical and
mechanical connection is stable before software attempts to reset
the attached device.

Heiko Stübner 662c738d99 usb: otg: gpio_vbus: Add otg transceiver events and notifiers
Commit 9ad63986c6 (pda_power: Add support for using otg transceiver events)
converted the pda-power driver to use otg events to determine the status
of the power supply.

As gpio-vbus didn't use otg events until now, this change breaks setups
of pda-power with a gpio-vbus transceiver.

This patch adds the necessary otg events and notifiers to gpio-vbus.

Axel Lin cc27c96c2b usb: convert drivers/usb/* to use module_platform_driver()
This patch converts the drivers in drivers/usb/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

Paul Gortmaker f940fcd8ea usb: Add export.h for EXPORT_SYMBOL/THIS_MODULE where needed
With module.h being implicitly everywhere via device.h, the absence
of explicitly including something for EXPORT_SYMBOL went unnoticed.
Since we are heading to fix things up and clean module.h from the
device.h file, we need to explicitly include these files now.

Use the lightweight version of the header that has just THIS_MODULE
and EXPORT_SYMBOL variants.

Paul Gortmaker 6eb0de8270 usb: Add module.h to drivers/usb consumers who really use it.
The situation up to this point meant that module.h was pretty
much everywhere, regardless of whether you asked for it or not.
We are fixing that, so give the USB folks who want it an actual
include of it.

Phil Carmody 497888cf69 treewide: fix potentially dangerous trailing ';' in #defined values/expressions
All these are instances of
  #define NAME value;
or
  #define NAME(params_opt) value;

These of course fail to build when used in contexts like
  if(foo $OP NAME)
  while(bar $OP NAME)
and may silently generate the wrong code in contexts such as
  foo = NAME + 1;    /* foo = value; + 1; */
  bar = NAME - 1;    /* bar = value; - 1; */
  baz = NAME & quux; /* baz = value; & quux; */

Reported on comp.lang.c,
Message-ID: <ab0d55fe-25e5-482b-811e-c475aa6065c3@c29g2000yqd.googlegroups.com>
Initial analysis of the dangers provided by Keith Thompson in that thread.

There are many more instances of more complicated macros having unnecessary
trailing semicolons, but this pile seems to be all of the cases of simple
values suffering from the problem. (Thus things that are likely to be found
in one of the contexts above, more complicated ones aren't.)

Moiz Sonasath 5bf54506b0 USB: OTG: Use work_queue in set_vbus for TWL6030 transciever
With this commit: cccad6d4b1
usb: otg: notifier: switch to atomic notifier

Following dumps are observed on attach/detach for MUSB HOST
mode and on a detach for MUSB Device mode.

BUG: sleeping function called from invalid context at kernel/mutex.c:85
where, the source is:
twl6030_usb_irq
->atomic_notifier_call_chain
 ->musb_otg_notifications
  ->twl6030_set_vbus
   ->twl_i2c_write_u8
    ->mutex_lock

This patch moves the i2c writes in set_vbus function to a
work-queue thereby avoiding I2C writes in atomic context.

Tested HOST and Device mode functionality on OMAP4460
