2012-05-17USB: gpio_vbus: wakeup support on GPIO VBUS interruptsShinya Kuribayashi1-0/+33
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'.

2012-05-17USB: gpio_vbus: handle IRQ flags properlyShinya Kuribayashi1-5/+6
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).

2012-05-17USB: gpio_vbus: use cached IRQ number for consistency with the probed oneShinya Kuribayashi1-4/+6
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.

2012-05-14USB: gpio_vbus: avoid consecutive vbus_session calls with the same "is_active"Shinya Kuribayashi1-2/+10
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.

2012-05-14USB: gpio_vbus: provide an appropriate debounce intervalShinya Kuribayashi1-4/+4
In commit c2344f13b59e007d782a3e591ebc551bc583a8b7 (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.

2012-04-12usb: otg: gpio_vbus: Add otg transceiver events and notifiersHeiko Stübner1-1/+14
Commit 9ad63986c606 (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.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next USB: transceiver changes for 3.4 Here we have a big rework done by Heikki Krogerus (thanks) which splits OTG functionality away from transceivers. We have known for quite a long time that struct otg_transceiver was a bad name for the structure, considering transceiver is far from being OTG-specific (see 4e67185).

2011-07-21treewide: fix potentially dangerous trailing ';' in #defined values/expressionsPhil Carmody1-1/+1
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.)

2011-07-01USB: OTG: Use work_queue in set_vbus for TWL6030 transcieverMoiz Sonasath1-6/+24
With this commit: cccad6d4b103e53fb3d1fc1467f654ecb572d047 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.

2011-05-27USB: TWL6025 allow different regulator nameGraeme Gregory1-1/+9
The twl6025 uses a different regulator for USB than the 6030 so select the correct regulator name depending on the subclass of device. Since V1 Use features passed via platform data instead of global variable.
