git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management updates from Rafael Wysocki: "As far as the number of commits goes, the top spot belongs to ACPI this time with cpufreq in the second position and a handful of PM core, PNP and cpuidle updates. They are fixes and cleanups mostly, as usual, with a couple of new features in the mix. The most visible change is probably that we will create struct acpi_device objects (visible in sysfs) for all devices represented in the ACPI tables regardless of their status and there will be a new sysfs attribute under those objects allowing user space to check that status via _STA. Consequently, ACPI device eject or generally hot-removal will not delete those objects, unless the table containing the corresponding namespace nodes is unloaded, which is extremely rare. Also ACPI container hotplug will be handled quite a bit differently and cpufreq will support CPU boost ("turbo") generically and not only in the acpi-cpufreq driver. Specifics: - ACPI core changes to make it create a struct acpi_device object for every device represented in the ACPI tables during all namespace scans regardless of the current status of that device. In accordance with this, ACPI hotplug operations will not delete those objects, unless the underlying ACPI tables go away. - On top of the above, new sysfs attribute for ACPI device objects allowing user space to check device status by triggering the execution of _STA for its ACPI object. From Srinivas Pandruvada. - ACPI core hotplug changes reducing code duplication, integrating the PCI root hotplug with the core and reworking container hotplug. - ACPI core simplifications making it use ACPI_COMPANION() in the code "glueing" ACPI device objects to "physical" devices. - ACPICA update to upstream version 20131218. This adds support for the DBG2 and PCCT tables to ACPICA, fixes some bugs and improves debug facilities. From Bob Moore, Lv Zheng and Betty Dall. - Init code change to carry out the early ACPI initialization earlier. That should allow us to use ACPI during the timekeeping initialization and possibly to simplify the EFI initialization too. From Chun-Yi Lee. - Clenups of the inclusions of ACPI headers in many places all over from Lv Zheng and Rashika Kheria (work in progress). - New helper for ACPI _DSM execution and rework of the code in drivers that uses _DSM to execute it via the new helper. From Jiang Liu. - New Win8 OSI blacklist entries from Takashi Iwai. - Assorted ACPI fixes and cleanups from Al Stone, Emil Goode, Hanjun Guo, Lan Tianyu, Masanari Iida, Oliver Neukum, Prarit Bhargava, Rashika Kheria, Tang Chen, Zhang Rui. - intel_pstate driver updates, including proper Baytrail support, from Dirk Brandewie and intel_pstate documentation from Ramkumar Ramachandra. - Generic CPU boost ("turbo") support for cpufreq from Lukasz Majewski. - powernow-k6 cpufreq driver fixes from Mikulas Patocka. - cpufreq core fixes and cleanups from Viresh Kumar, Jane Li, Mark Brown. - Assorted cpufreq drivers fixes and cleanups from Anson Huang, John Tobias, Paul Bolle, Paul Walmsley, Sachin Kamat, Shawn Guo, Viresh Kumar. - cpuidle cleanups from Bartlomiej Zolnierkiewicz. - Support for hibernation APM events from Bin Shi. - Hibernation fix to avoid bringing up nonboot CPUs with ACPI EC disabled during thaw transitions from Bjørn Mork. - PM core fixes and cleanups from Ben Dooks, Leonardo Potenza, Ulf Hansson. - PNP subsystem fixes and cleanups from Dmitry Torokhov, Levente Kurusa, Rashika Kheria. - New tool for profiling system suspend from Todd E Brandt and a cpupower tool cleanup from One Thousand Gnomes" * tag 'pm+acpi-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (153 commits) thermal: exynos: boost: Automatic enable/disable of BOOST feature (at Exynos4412) cpufreq: exynos4x12: Change L0 driver data to CPUFREQ_BOOST_FREQ Documentation: cpufreq / boost: Update BOOST documentation cpufreq: exynos: Extend Exynos cpufreq driver to support boost cpufreq / boost: Kconfig: Support for software-managed BOOST acpi-cpufreq: Adjust the code to use the common boost attribute cpufreq: Add boost frequency support in core intel_pstate: Add trace point to report internal state. cpufreq: introduce cpufreq_generic_get() routine ARM: SA1100: Create dummy clk_get_rate() to avoid build failures cpufreq: stats: create sysfs entries when cpufreq_stats is a module cpufreq: stats: free table and remove sysfs entry in a single routine cpufreq: stats: remove hotplug notifiers cpufreq: stats: handle cpufreq_unregister_driver() and suspend/resume properly cpufreq: speedstep: remove unused speedstep_get_state platform: introduce OF style 'modalias' support for platform bus PM / tools: new tool for suspend/resume performance optimization ACPI: fix module autoloading for ACPI enumerated devices ACPI: add module autoloading support for ACPI enumerated devices ACPI: fix create_modalias() return value handling ...

git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip Pull Xen updates from Konrad Rzeszutek Wilk: "Two major features that Xen community is excited about: The first is event channel scalability by David Vrabel - we switch over from an two-level per-cpu bitmap of events (IRQs) - to an FIFO queue with priorities. This lets us be able to handle more events, have lower latency, and better scalability. Good stuff. The other is PVH by Mukesh Rathor. In short, PV is a mode where the kernel lets the hypervisor program page-tables, segments, etc. With EPT/NPT capabilities in current processors, the overhead of doing this in an HVM (Hardware Virtual Machine) container is much lower than the hypervisor doing it for us. In short we let a PV guest run without doing page-table, segment, syscall, etc updates through the hypervisor - instead it is all done within the guest container. It is a "hybrid" PV - hence the 'PVH' name - a PV guest within an HVM container. The major benefits are less code to deal with - for example we only use one function from the the pv_mmu_ops (which has 39 function calls); faster performance for syscall (no context switches into the hypervisor); less traps on various operations; etc. It is still being baked - the ABI is not yet set in stone. But it is pretty awesome and we are excited about it. Lastly, there are some changes to ARM code - you should get a simple conflict which has been resolved in #linux-next. In short, this pull has awesome features. Features: - FIFO event channels. Key advantages: support for over 100,000 events (2^17), 16 different event priorities, improved fairness in event latency through the use of FIFOs. - Xen PVH support. "It’s a fully PV kernel mode, running with paravirtualized disk and network, paravirtualized interrupts and timers, no emulated devices of any kind (and thus no qemu), no BIOS or legacy boot — but instead of requiring PV MMU, it uses the HVM hardware extensions to virtualize the pagetables, as well as system calls and other privileged operations." (from "The Paravirtualization Spectrum, Part 2: From poles to a spectrum") Bug-fixes: - Fixes in balloon driver (refactor and make it work under ARM) - Allow xenfb to be used in HVM guests. - Allow xen_platform_pci=0 to work properly. - Refactors in event channels" * tag 'stable/for-linus-3.14-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: (52 commits) xen/pvh: Set X86_CR0_WP and others in CR0 (v2) MAINTAINERS: add git repository for Xen xen/pvh: Use 'depend' instead of 'select'. xen: delete new instances of __cpuinit usage xen/fb: allow xenfb initialization for hvm guests xen/evtchn_fifo: fix error return code in evtchn_fifo_setup() xen-platform: fix error return code in platform_pci_init() xen/pvh: remove duplicated include from enlighten.c xen/pvh: Fix compile issues with xen_pvh_domain() xen: Use dev_is_pci() to check whether it is pci device xen/grant-table: Force to use v1 of grants. xen/pvh: Support ParaVirtualized Hardware extensions (v3). xen/pvh: Piggyback on PVHVM XenBus. xen/pvh: Piggyback on PVHVM for grant driver (v4) xen/grant: Implement an grant frame array struct (v3). xen/grant-table: Refactor gnttab_init xen/grants: Remove gnttab_max_grant_frames dependency on gnttab_init. xen/pvh: Piggyback on PVHVM for event channels (v2) xen/pvh: Update E820 to work with PVH (v2) xen/pvh: Secondary VCPU bringup (non-bootup CPUs) ...

2014-01-07mfd: ti_am335x_tscadc: Don't read back REG_SESebastian Andrzej Siewior1-2/+2
The purpose of reg_se_cache has been defeated. It should avoid the read-back of the register to avoid the latency and the fact that the bits are reset to 0 after the individual conversation took place. The reason why this is required like this to work, is that read-back of the register removes the bits of the ADC so they do not start another conversation after the register is re-written from the TSC side for the update. To avoid the not required read-back I introduce a "set once" variant which does not update the cache mask. After the conversation completes, the bit is removed from the SE register anyway and we don't plan a new conversation "any time soon". The current set function is renamed to set_cache to distinguish the two operations. This is a small preparation for a larger sync-rework.

The driver can't deal with two entries its keymap having the same keycode. When this happens it will get confused about whether the key is down or up and will cause some screwy behavior. We need to have two entries for KEY_BACKSLASH to handle US and UK keyboards. Specifically: * On the US keyboard the backslash key (above enter) is r3 c11 and is supposed to be reported as BACKSLASH. * On the UK keyboard the # key (left of enter) is r4 c10 and is supposed to be reported as BACKSLASH. * On the UK keyboard the \ key (left of Z) is r2 c7 and is supposed to be reported as KEY_102ND. Note that both keyboards (US and UK) have only one physical backslash key so the constraint that each physical key should have its own keycode still stands.

git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/cleanup From Stephen Warren: ARM: tegra: implement common DMA and resets DT bindings This series converts the Tegra DTs and drivers to use the common/ standard DMA and reset bindings, rather than custom bindings. It also adds complete documentation for the Tegra clock bindings without actually changing any binding definitions. This conversion relies on a few sets of patches in branches from outside the Tegra tree: 1) A patch to add an DMA channel request API which allows deferred probe to be implemented. 2) A patch to implement a common part of the of_xlate function for DMA controllers. 3) Some ASoC patches (which in turn rely on (1) above), which support deferred probe during DMA channel allocation. 4) The Tegra clock driver changes for 3.14. Consequently, this branch is based on a merge of all of those external branches. In turn, this branch is or will be pulled into a few places that either rely on features introduced here, or would otherwise conflict with the patches: a) Tegra's own for-3.14/powergate and for-4.14/dt branches, to avoid conflicts. b) The DRM tree, which introduces new code that relies on the reset controller framework introduced in this branch, and to avoid conflicts. * tag 'tegra-for-3.14-dmas-resets-rework' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: (30 commits) spi: tegra: checking for ERR_PTR instead of NULL ASoC: tegra: update module reset list for Tegra124 clk: tegra: remove bogus PCIE_XCLK clk: tegra: remove legacy reset APIs ARM: tegra: remove legacy DMA entries from DT ARM: tegra: remove legacy clock entries from DT USB: EHCI: tegra: use reset framework Input: tegra-kbc - use reset framework serial: tegra: convert to standard DMA DT bindings serial: tegra: use reset framework spi: tegra: convert to standard DMA DT bindings spi: tegra: use reset framework staging: nvec: use reset framework i2c: tegra: use reset framework ASoC: tegra: convert to standard DMA DT bindings ASoC: tegra: allocate AHUB FIFO during probe() not startup() ASoC: tegra: call pm_runtime APIs around register accesses ASoC: tegra: use reset framework dma: tegra: register as an OF DMA controller dma: tegra: use reset framework ...

The current assumption in the elantech driver that hw version 3 touchpads are never clickpads and hw version 4 touchpads are always clickpads is wrong. There are several bug reports for this, ie: https://bugzilla.redhat.com/show_bug.cgi?id=1030802 http://superuser.com/questions/619582/right-elantech-touchpad-button-not-working-in-linux I've spend a couple of hours wading through various bugzillas, launchpads and forum posts to create a list of fw-versions and capabilities for different laptop models to find a good method to differentiate between clickpads and versions with separate hardware buttons. Which shows that a device being a clickpad is reliable indicated by bit 12 being set in the fw_version. I've included the gathered list inside the driver, so that we've this info at hand if we need to revisit this later.

2013-12-15Input: zforce - fix possible driver hang during suspendHeiko Stübner1-6/+15
handle_level_irq masks the interrupt before handling it, and only unmasks it after the handler is finished. So when a touch event happens after threads are suspended, but before the system is fully asleep the irq handler tries to wakeup the thread which will only happen on the next resume, resulting in the wakeup event never being sent and the driver not being able to wake the system from sleep due to the masked irq. Therefore move the wakeup_event to a small non-threaded handler. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
