| | * | Input: db9 - store object at correct indexSudip Mukherjee2015-10-051-9/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The variable i is used to check the port to attach to and we are supposed to save the reference of struct db9 in the location given by db9_base[i]. But after finding out the index, i is getting modified again so we saved in a wrong index. While at it mark db9_base[i] as NULL after it is freed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver depends on GOLDFISH but there isn't a build dependency so it's a good idea to allow the driver to be built even if that option is disabled, if the COMPILE_TEST option is enabled. That way, the driver can be built with a config generated by make allyesconfig and can be checked if a patch would break the build.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the cases where the gpio chip fails to acquire the current state an error is reported back to gpio_keys. This is currently interpreted as if the line went high, which just confuses the developer. This patch introduces an error print in this case and skipps the reporting of a input event; to aid in debugging this issue.

The following change will add generic register and bit mask support to the DA9063 OnKey. The following alterations have been made to the DA9063 OnKey: - Addition of a da906x_chip_config structure to hold all generic registers and bitmasks for this type of OnKey component. - Addition of an struct of_device_id table for DA9063 and DA9062 defaults - Refactoring functions to use struct da9063_onkey accesses to generic registers/masks instead of using defines from registers.h - Re-work of da9063_onkey_probe() to use of_match_node() and dev_get_regmap() to provide initialisation of generic registers and masks and access to regmap Signed-off-by: Steve Twiss <stwiss.opensource@diasemi.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

The newer gpio framework takes into account these flags when setting gpio values. Since the values being output were based on voltage and not logic they change to reflect this difference. Also use gpiod_set_value_cansleep since wake and reset pins can be provided by bus based io expanders. Switch from msleep(5) to udelay_range(5000,6000) to avoid check patch warning.

First off, the Collaborative Processor Performance Control interface (version 2) defined by ACPI will now be supported on ARM64 along with a cpufreq frontend for CPU performance scaling. Second, ACPI gets a new infrastructure for the early probing of IRQ chips and clock sources (along the lines of the existing similar mechanism for DT). Next, the ACPI core and the generic device properties API will now support a recently introduced hierarchical properties extension of the _DSD (Device Specific Data) ACPI device configuration object. If the ACPI platform firmware uses that extension to organize device properties in a hierarchical way, the kernel will automatically handle it and make those properties available to device drivers via the generic device properties API. It also will be possible to build the ACPICA's AML interpreter debugger into the kernel now and use that to diagnose AML-related problems more efficiently. In the future, this should make it possible to single-step AML execution and do similar things. Interesting stuff, although somewhat experimental at this point. Finally, the PM core gets a new mechanism that can be used by device drivers to distinguish between suspend-to-RAM (based on platform firmware support) and suspend-to-idle (or other variants of system suspend the platform firmware is not involved in) and possibly optimize their device suspend/resume handling accordingly. In addition to that, some existing features are re-organized quite substantially. First, the ACPI-based handling of PCI host bridges on x86 and ia64 is unified and the common code goes into the ACPI core (so as to reduce code duplication and eliminate non-essential differences between the two architectures in that area). Second, the Operating Performance Points (OPP) framework is reorganized to make the code easier to find and follow. Next, the cpufreq core's sysfs interface is reorganized to get rid of the "primary CPU" concept for configurations in which the same performance scaling settings are shared between multiple CPUs. Finally, some interfaces that aren't necessary any more are dropped from the generic power domains framework. On top of the above we have some minor extensions, cleanups and bug fixes in multiple places, as usual. Specifics: - ACPICA update to upstream revision 20150930 (Bob Moore, Lv Zheng). The most significant change is to allow the AML debugger to be built into the kernel. On top of that there is an update related to the NFIT table (the ACPI persistent memory interface) and a few fixes and cleanups. - ACPI CPPC2 (Collaborative Processor Performance Control v2) support along with a cpufreq frontend (Ashwin Chaugule). This can only be enabled on ARM64 at this point. - New ACPI infrastructure for the early probing of IRQ chips and clock sources (Marc Zyngier). - Support for a new hierarchical properties extension of the ACPI _DSD (Device Specific Data) device configuration object allowing the kernel to handle hierarchical properties (provided by the platform firmware this way) automatically and make them available to device drivers via the generic device properties interface (Rafael Wysocki). - Generic device properties API extension to obtain an index of certain string value in an array of strings, along the lines of of_property_match_string(), but working for all of the supported firmware node types, and support for the "dma-names" device property based on it (Mika Westerberg). - ACPI core fix to parse the MADT (Multiple APIC Description Table) entries in the order expected by platform firmware (and mandated by the specification) to avoid confusion on systems with more than 255 logical CPUs (Lukasz Anaczkowski). - Consolidation of the ACPI-based handling of PCI host bridges on x86 and ia64 (Jiang Liu). - ACPI core fixes to ensure that the correct IRQ number is used to represent the SCI (System Control Interrupt) in the cases when it has been re-mapped (Chen Yu). - New ACPI backlight quirk for Lenovo IdeaPad S405 (Hans de Goede). - ACPI EC driver fixes (Lv Zheng). - Assorted ACPI fixes and cleanups (Dan Carpenter, Insu Yun, Jiri Kosina, Rami Rosen, Rasmus Villemoes). - New mechanism in the PM core allowing drivers to check if the platform firmware is going to be involved in the upcoming system suspend or if it has been involved in the suspend the system is resuming from at the moment (Rafael Wysocki). This should allow drivers to optimize their suspend/resume handling in some cases and the changes include a couple of users of it (the i8042 input driver, PCI PM). - PCI PM fix to prevent runtime-suspended devices with PME enabled from being resumed during system suspend even if they aren't configured to wake up the system from sleep (Rafael Wysocki). - New mechanism to report the number of a wakeup IRQ that woke up the system from sleep last time (Alexandra Yates). - Removal of unused interfaces from the generic power domains framework and fixes related to latency measurements in that code (Ulf Hansson, Daniel Lezcano). - cpufreq core sysfs interface rework to make it handle CPUs that share performance scaling settings (represented by a common cpufreq policy object) more symmetrically (Viresh Kumar). This should help to simplify the CPU offline/online handling among other things. - cpufreq core fixes and cleanups (Viresh Kumar). - intel_pstate fixes related to the Turbo Activation Ratio (TAR) mechanism on client platforms which causes the turbo P-states range to vary depending on platform firmware settings (Srinivas Pandruvada). - intel_pstate sysfs interface fix (Prarit Bhargava). - Assorted cpufreq driver (imx, tegra20, powernv, integrator) fixes and cleanups (Bai Ping, Bartlomiej Zolnierkiewicz, Shilpasri G Bhat, Luis de Bethencourt). - cpuidle mvebu driver cleanups (Russell King). - OPP (Operating Performance Points) framework code reorganization to make it more maintainable (Viresh Kumar). - Intel Broxton support for the RAPL (Running Average Power Limits) power capping driver (Amy Wiles). - Assorted power management code fixes and cleanups (Dan Carpenter, Geert Uytterhoeven, Geliang Tang, Luis de Bethencourt, Rasmus Villemoes)" * tag 'pm+acpi-4.4-rc1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (108 commits) cpufreq: postfix policy directory with the first CPU in related_cpus cpufreq: create cpu/cpufreq/policyX directories cpufreq: remove cpufreq_sysfs_{create|remove}_file() cpufreq: create cpu/cpufreq at boot time cpufreq: Use cpumask_copy instead of cpumask_or to copy a mask cpufreq: ondemand: Drop unnecessary locks from update_sampling_rate() PM / Domains: Merge measurements for PM QoS device latencies PM / Domains: Don't measure ->start|stop() latency in system PM callbacks PM / clk: Fix broken build due to non-matching code and header #ifdefs ACPI / Documentation: add copy_dsdt to ACPI format options ACPI / sysfs: correctly check failing memory allocation ACPI / video: Add a quirk to force native backlight on Lenovo IdeaPad S405 ACPI / CPPC: Fix potential memory leak ACPI / CPPC: signedness bug in register_pcc_channel() ACPI / PAD: power_saving_thread() is not freezable ACPI / PM: Fix incorrect wakeup IRQ setting during suspend-to-idle ACPI: Using correct irq when waiting for events ACPI: Use correct IRQ when uninstalling ACPI interrupt handler cpuidle: mvebu: disable the bind/unbind attributes and use builtin_platform_driver cpuidle: mvebu: clean up multiple platform drivers ...

Later we limited this to Dell laptops only because of reports that this broke things on non Dell laptops. Now it turns out that this breaks things on the Dell Latitude D600 too. So it seems that only the Dell Latitude D420/430/620/630, which all share the same touchpad / stick combo, have these separate bits. This patch limits the checking of the separate bits to only these models fixing regressions with other models.

So the bit[15] of the value got from SPI bus is always 0. But when SPI bus congfigures the MOSI and MISO in high level during the SPI idle mode, the bit[15] of the value get from SPI is always 1.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If parkbd_allocate_serio() fails to allocate memory we are releasing the parport but we missed unregistering the device. As a result this device with exclusive access to that parport remains registered. And no other device will be able to use that parport even though this driver has failed to load.

However during initial write of the uinput structure that contains min/max data for all possible axes none of them are reflected in dev->absbit yet and so we were skipping over all of them and were not allocating absinfo memory which caused crash later when driver tried to sens EV_ABS events: <1>[ 15.064330] BUG: unable to handle kernel NULL pointer dereference at 0000000000000024 <1>[ 15.064336] IP: [<ffffffff8163f142>] input_handle_event+0x232/0x4e0 <4>[ 15.064343] PGD 0 <4>[ 15.064345] Oops: 0000 [#1] SMP Fixes: b6d30968d86c45a7bb599eaca13ff048d3fa576c Cc: stable@vger.kernel.org Reported-by: Stephen Chandler Paul <cpaul@redhat.com> Tested-by: Stephen Chandler Paul <cpaul@redhat.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
