* Input: polled device power savingStephen Hemminger2007-09-26

* Input: gpio_keys - verify that supplied GPIO numbers are validAnti Sullin2007-09-26
| | | | | | | | | | | | As David Brownell pointed out, gpio_keys driver does not check return code of gpio_to_irq(). This patch adds the gpio_to_irq return code check to gpio_keys and moves the IRQ edge type setting to request_irq flags to avoid changing the irq type before we have confirmed we can use it.

* Input: i8042 - give more trust to PNP data on i386Dmitry Torokhov2007-07-18
| | | | | | | | | | | | On some boxes that don't have PS/2 mice connected at startup BIOS completely disables AUX port and attempts to access it result in hosed keyboard. Historically we do not trust ACPI/PNP data on i386 and try to poke AUX port even if we did not find an active PNP node for it. However in cases when BIOS writers got KBD port properly described we can assume that they did the right thing for AUX port as well. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

* Input: ads7846 - re-check pendown status before reporting eventsSemih Hazar2007-07-18
| | | | | | | | | | | | | | Pendown status from the PENIRQ pin is currently read only at the beginning of a sample set. If the pen is lifted just after sampling has began then sampled values become wrong. This patch adds an optional platform penirq_recheck_delay attribute. If non-zero, samples are only reported to the input subsystem if PENIRQ is still active that long after the samples taken.

* Input: ads7846 - introduce sample settling delaySemih Hazar2007-07-18
| | | | | | | | | | | | | | | The ads7846 driver has support for filtering, but when the chip gets deselected between samples this causes noise. This patch adds support for an optional settling delay time, so that two consecutive samples will be taken with the specified delay time apart. This ensures that the chip won't be deselected, so the noise won't appear. Filtering can still be done, but will have less work to do since each time a new sample is taken the same delay applies.

* Input: xpad - add support for leds on xbox 360 padJan Kratochvil2007-07-18
| | | | | | | | | | | | | | | | | | Export LEDs on Xbox360 pad via led subsystem as a single device in /sys/class/leds/xpad[0-9]+. Xbox360 pad has four leds, which form a circle. Unfortunately the leds can't be controlled independently and can only display a predefined set of patterns (for example one is turned on wile others are off or a rotating pattern - 1-2-3-4). To activate a pattern one needs to send a specific command to the device (see http://www.free60.org/wiki/Gamepad). Led subsystem allows us to set brightness, but there is nothing like brightness on this device. So brightness is actually interpreted as the command (only values between 0 and 14 are accepted).

* Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki2007-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

* sysfs: kill unnecessary attribute->ownerTejun Heo2007-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded. For more info regarding lifetime rule cleanup, please read the following message. http://article.gmane.org/gmane.linux.kernel/510293 (tweaked by Greg to not delete the field just yet, to make it easier to merge things properly.)
