* | | | | | Input: wm9712 - fix wrong pen up readingsMarkus Pargmann2013-03-12

This patch assures that this is really a pen up event and not a false reading. Based on wm9712: pen up by Teresa Gámez and Christian Hemp.

* | | | | | Input: wm97xx - drop out of range inputsMarkus Pargmann2013-03-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With fast movements, there occured some out of screen jumps with my touchscreen. The abs_x and abs_y module parameters should fix this by default, but the driver doesn't actively checks the x/y coordinates. Instead it seems that the input layer was supposed to drop out of range inputs, as described in the comments: "These parameters are used to help the input layer discard out of range readings and reduce jitter etc" The input layer documentation describes that values that are not in the absolute range are also accepted. So this patch adds a check within the driver.

The interrupt mode of the chip is not set via devicetree, as it is not a property of the hardware but instead only a preferred type of operation. This should probably be made settable via configfs in the future. The option set as default is the mode the datasheet mentions as default.

Therefore pull the reset handling directly into the driver and remove the callbacks from the driver. If extended device setup is needed at some later point, power-sequences would probably be the solution of choice.

The i.MX6q sabrelite platform equips an egalax touchscreen controller, and this platform already transfered to GENERIC_GPIO framework, to support this driver, we use a more generic way to get gpio. Add a return value checking for waking up the controller in the probe function, this guarantee only a workable device can pass init.

A lot of activities this round including considerable API and behavior cleanups. * delayed_work combines a timer and a work item. The handling of the timer part has always been a bit clunky leading to confusing cancelation API with weird corner-case behaviors. delayed_work is updated to use new IRQ safe timer and cancelation now works as expected. * Another deficiency of delayed_work was lack of the counterpart of mod_timer() which led to cancel+queue combinations or open-coded timer+work usages. mod_delayed_work[_on]() are added. These two delayed_work changes make delayed_work provide interface and behave like timer which is executed with process context. * A work item could be executed concurrently on multiple CPUs, which is rather unintuitive and made flush_work() behavior confusing and half-broken under certain circumstances. This problem doesn't exist for non-reentrant workqueues. While non-reentrancy check isn't free, the overhead is incurred only when a work item bounces across different CPUs and even in simulated pathological scenario the overhead isn't too high. All workqueues are made non-reentrant. This removes the distinction between flush_[delayed_]work() and flush_[delayed_]_work_sync(). The former is now as strong as the latter and the specified work item is guaranteed to have finished execution of any previous queueing on return. * In addition to the various bug fixes, Lai redid and simplified CPU hotplug handling significantly. * Joonsoo introduced system_highpri_wq and used it during CPU hotplug. There are two merge commits - one to pull in IRQ safe timer from tip/timers/core and the other to pull in CPU hotplug fixes from wq/for-3.6-fixes as Lai's hotplug restructuring depended on them." Fixed a number of trivial conflicts, but the more interesting conflicts were silent ones where the deprecated interfaces had been used by new code in the merge window, and thus didn't cause any real data conflicts. Tejun pointed out a few of them, I fixed a couple more. * 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: (46 commits) workqueue: remove spurious WARN_ON_ONCE(in_irq()) from try_to_grab_pending() workqueue: use cwq_set_max_active() helper for workqueue_set_max_active() workqueue: introduce cwq_set_max_active() helper for thaw_workqueues() workqueue: remove @delayed from cwq_dec_nr_in_flight() workqueue: fix possible stall on try_to_grab_pending() of a delayed work item workqueue: use hotcpu_notifier() for workqueue_cpu_down_callback() workqueue: use __cpuinit instead of __devinit for cpu callbacks workqueue: rename manager_mutex to assoc_mutex workqueue: WORKER_REBIND is no longer necessary for idle rebinding workqueue: WORKER_REBIND is no longer necessary for busy rebinding workqueue: reimplement idle worker rebinding workqueue: deprecate __cancel_delayed_work() workqueue: reimplement cancel_delayed_work() using try_to_grab_pending() workqueue: use mod_delayed_work() instead of __cancel + queue workqueue: use irqsafe timer for delayed_work workqueue: clean up delayed_work initializers and add missing one workqueue: make deferrable delayed_work initializer names consistent workqueue: cosmetic whitespace updates for macro definitions workqueue: deprecate system_nrt[_freezable]_wq workqueue: deprecate flush[_delayed]_work_sync() ...

Mark them deprecated and convert all users to flush[_delayed]_work(). If you're cc'd and wondering what's going on: Now all workqueues are non-reentrant and the regular flushes guarantee that the work item is not pending or running on any CPU on return, so there's no reason to use the sync flushes at all and they're going away. This patch doesn't make any functional difference.

It's the introduction of the first multiplatform support on ARM, and with this (and the later branch) merged, it is now possible to build one kernel that contains support for highbank, vexpress, mvebu, socfpga, and picoxcell. More platforms will be convered over in the next few releases. Two critical last things had to be done for this to be practical and possible: * Today each platform has its own include directory under mach-<mach>/include/mach/*, and traditionally that is where a lot of driver/platform shared definitions have gone, such as platform data structures. They now need to move out to a common location instead, and this branch moves a large number of those out to include/linux/platform_data. * Each platform used to list the device trees to compile for its boards in mach-<mach>/Makefile.boot. Both of the above changes will mean that there are some merge conflicts to come (and some to resolve here). It's a one-time move and once it settles in, we should be good for quite a while. Sorry for the overhead."

Some work with usbhid and some work with usbtouchscreen, but there is no easy way to differentiate. Sending an eGalax diagnostic packet seems to kick them all into using the right protocol for usbtouchscreen, so we can continue to bind them all there (as opposed to handing some off to usbhid). This fixes a regression for devices that were claimed by (and worked with) usbhid prior to commit 139ebe8dc80dd74cb2ac9f5603d18fbf5cff049f ("Input: usbtouchscreen - fix eGalax HID ignoring"), which made usbtouchscreen claim them instead. With this patch they will still be claimed by usbtouchscreen, but they will actually report events usbtouchscreen can understand. Note that these devices will be limited to the usbtouchscreen feature set so e.g. dual touch features are not supported. I have the distinct pleasure of needing to support devices of both types and have tested accordingly.
