2009-12-01Input: keyboard - fix lack of locking when traversing handler->h_listDmitry Torokhov
Keyboard handler should not attempt to traverse handler->h_list on its own, without any locking, otherwise it races with registering and unregistering of input handles which leads to crashes. Introduce input_handler_for_each_handle() helper that allows safely iterate over all handles attached to a particular handler and switch keyboard handler to use it.

2009-11-30Input: gpio_keys - scan gpio state at probe and resume timeDaniel Mack
We need to read and report gpio state when we bind the driver to the device and upon resume so that userspace has correct state of the switches (and keys but they are less important since, even if they are happened to be pressed, we'd expect them to be released fairly soon).

2009-11-29Input: keyboard - add locking around event handlingDmitry Torokhov
Keyboard input handler is multiplexing events form all keyboard-like devices in the system. Because of that per-device lock provided by input core is not enough to prevent clashes in ked_event() and we need our own lock to ensure that only one thread at a time executing kbd_event().

2009-11-23Input: polled device - do not start polling if interval is zeroSamu Onkalo
If the poll interval is set to 0 via new sysfs entry and device is opened after that, polling is started with interval 0. This causes huge CPU load.

2009-11-23Input: add S3C24XX touchscreen driverArnaud Patard
S3C24XX touchscreen driver, originally written by Arnaud Patard and other contributors. The driver has had substantial testing as well as a number of tidying up passes done by Ben Dooks, as noted: - added kernel-doc comments to most of the routines - removed old code from pre adc framework days - updated device probe code to use platform id list matching - cleaned up debug, since printk() now has timestamp feature - ensure code uses dev_() reporting macros where necessary - remove ABS_PRESSURE reporting, tslib can be fixed - ensure timer is removed on driver exit - move to using dev_pmops for power management Signed-off-by: Arnaud Patard <arnaud.patard@rtp-net.org> Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Simtec Linux Team <linux@simtec.co.uk> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

Make the driver to generate BTN_0..BTN_3 events in response.

Commit 0c570cdeb8fdfcb354a3e9cd81bfc6a09c19de0c (PM / yenta: Fix cardbus suspend/resume regression) caused resume to fail on systems with two CardBus bridges. While the exact nature of the failure is not known at the moment, it can be worked around by splitting the yenta resume into an early part, executed during the early phase of resume, that will only resume the socket and power it up if there was a card in it during suspend, and a late part, executed during "regular" resume, that will carry out all of the remaining yenta resume operations.

2009-11-02i2c-mpc: Do not generate STOP after read.Joakim Tjernlund
The driver always ends a read with a STOP condition which breaks subsequent I2C reads/writes in the same transaction as these expect to do a repeated START(ReSTART). This will also help I2C multimaster as the bus will not be released after the first read, but when the whole transaction ends.

2009-11-02i915: fix intel graphics suspend breakage due to resume/lid event confusionLinus Torvalds
In commit c1c7af60892070e4b82ad63bbfb95ae745056de0 ("drm/i915: force mode set at lid open time") the intel graphics driver was taught to restore the LVDS mode on lid open. That caused problems with interaction with the suspend/resume code, which commonly runs at the same time (suspend is often caused by the lid close event, while lid open is commonly a resume event), which was worked around with in commit 06891e27a9b5dba5268bb80e41a283f51335afe7 ("drm/i915: fix suspend/resume breakage in lid notifier"). However, in the meantime the lid event code had also grown a user event notifier (commit 06324194eee97a51b5f172270df49ec39192d6cc: "drm/i915: generate a KMS uevent at lid open/close time"), and now _that_ causes problems with suspend/resume and some versions of Xorg reacting to those uevents by setting the mode. So this effectively reverts that commit 06324194ee, and makes the lid open protection logic against suspend/resume more explicit. This fixes at least one laptop. See http://bugzilla.kernel.org/show_bug.cgi?id=14484 for more details.
