2012-07-06Merge branch 'for-linus' of ↵Linus Torvalds6-9/+12
git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input Pull input layer fixes from Dmitry Torokhov: "Two fixes for regressions in Wacom driver and fixes for drivers using threaded IRQ framework without specifying IRQF_ONESHOT." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: request threaded-only IRQs with IRQF_ONESHOT Input: wacom - don't retrieve touch_max when it is predefined Input: wacom - fix retrieving touch_max bug Input: fix input.h kernel-doc warning
2012-07-04Input: request threaded-only IRQs with IRQF_ONESHOTLars-Peter Clausen6-9/+12
Since commit 1c6c69525b ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request will fail. This patch adds the IRQF_ONESHOT to input drivers where it is missing. Not modified by this patch are those drivers where the requested IRQ will always be a nested IRQ (e.g. because it's part of an MFD), since for this special case IRQF_ONESHOT is not required to be specified when requesting the IRQ.

Pull arm-soc driver specific updates from Olof Johansson: "These changes are specific to some driver that may be used by multiple boards or socs.

2012-05-10Input: matrix-keymap - wire up device tree supportDmitry Torokhov1-24/+32
When platform keymap is not supplied to matrix_keypad_build_keymap() and device tree support is enabled, try locating specified property and load keymap from it. If property name is not defined, try using "linux,keymap". Based on earlier patch by Viresh Kumar <viresh.kumar@st.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

Pull ARM platform updates from Russell King: "This covers platform stuff for platforms I have a direct interest in (iow, I have the hardware). Essentially: - as we no longer support any other Acorn platforms other than RiscPC anymore, we can collect all that code into mach-rpc. - convert Acorn expansion card stuff to use IRQ allocation functions, and get rid of NO_IRQ from there. - cleanups to the ebsa110 platform to move some private stuff out of its header files. - large amount of SA11x0 updates: - conversion of private DMA implementation to DMA engine support (this actually gives us greater flexibility in drivers over the old API.) - re-worked ucb1x00 updates - convert to genirq, remove sa11x0 dependencies, fix various minor issues - move platform specific sa11x0 framebuffer data into platform files in arch/arm instead of keeping this in the driver itself - update sa11x0 IrDA driver for DMA engine, and allow it to use DMA for SIR transmissions as well as FIR - rework sa1111 support for genirq, and irq allocation - fix sa1111 IRQ support so it works again - use sparse IRQ support After this, I have one more pull request remaining from my current set, which I think is going to be the most problematical as it generates 8 conflicts."

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.

Tegra kbc cannot detect exact keypress causing wakeup in interrupt mode. Allow wakeup keypress to be reported for certain platforms. Signed-off-by: Rakesh Iyer <riyer@nvidia.com> Acked-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2011-12-30Input: tegra-kbc - add device tree bindingsOlof Johansson1-8/+84
This adds a simple device tree binding to the tegra keyboard controller. Also, mark the default keymap as __devinitdata since it is not referenced after boot. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
