2012-01-13module_param: make bool parameters really bool (drivers & misc)Rusty Russell9-16/+16
module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Acked-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

Some bcm5974 trackpads have a physical button beneath the physical surface. This patch sets the property bit so user space applications can detect the trackpad type and act accordingly.

If serio_raw_write was always returning number of bytes successfully sent to serio port and never signalled error condition to the caller. Change it so that for completely failed transfers appropriate error code returned to the caller (partially successful writes still return number of bytes transferred).

2012-01-04Xen: consolidate and simplify struct xenbus_driver instantiationJan Beulich1-5/+2
The 'name', 'owner', and 'mod_name' members are redundant with the identically named fields in the 'driver' sub-structure. Rather than switching each instance to specify these fields explicitly, introduce a macro to simplify this. Eliminate further redundancy by allowing the drvname argument to DEFINE_XENBUS_DRIVER() to be blank (in which case the first entry from the ID table will be used for .driver.name). Also eliminate the questionable xenbus_register_{back,front}end() wrappers - their sole remaining purpose was the checking of the 'owner' field, proper setting of which shouldn't be an issue anymore when the macro gets used. v2: Restore DRV_NAME for the driver name in xen-pciback.

2011-12-30Input: samsung-keypad - implement runtime power management supportMark Brown1-7/+80
When runtime power management is enabled put the Samsung keypad driver into suspend mode with wakeups disabled whenever the device is open but a key is not actually been pressed. As well as saving a trivial amount of power this will support the use of SoC wide idle modes which put the entire device into a retention mode and use explicit wakeup sources to exit. Since not all of the interrupt controllers used with the driver support set_irq_wake() (though they all do the right thing) and there's a nasty WARN() when we disable wake after failing to enable it keep track of the current wake status from runtime PM and only disable wake if we managed to enable it; I'm not entirely sure why this doesn't affect the existing uses of the API in the driver. System suspend is unaffected as the driver core will runtime resume any suspended devices prior to system suspend.

Since commit 6384fd "ARM: pxa: rename IRQ_GPIO to PXA_GPIO_TO_IRQ", I got below buid errors due to implicit declaration of function 'IRQ_GPIO'. Use common gpio_to_irq() to replace machine dependant macro IRQ_GPIO().

2011-12-27Input: add driver for AUO In-Cell touchscreens using pixcir ICsHeiko Stübner3-0/+666
Some displays from AUO have a so called in-cell touchscreen, meaning it is built directly into the display unit. Touchdata is gathered through PIXCIR Tango-ICs and processed in an Atmel ATmega168P with custom firmware. Communication between the host system and ATmega is done via I2C. Devices using this touch solution include the Dell Streak5 and the family of Qisda ebook readers. The driver reports single- and multi-touch events including touch area values.

2011-12-25PM / input / touchscreen: Make st1232 use device PM QoS constraintsRafael J. Wysocki1-1/+12
Make the st1232 driver use dev_pm_qos_add_ancestor_request() to add a device PM QoS latency constraint for the controller it depends on, so that the controller won't go into an overly deep low-power state when the touchscreen has to be particularly responsive (e.g. when the user moves his or her finger on it). This change is based on a prototype patch from Guennadi Liakhovetski. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
