git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid Pull HID updates from Jiri Kosina: - quite a few firmware fixes for RMI driver by Andrew Duggan - huion and uclogic drivers have been substantially overlaping in functionality laterly. This redundancy is fixed by hid-huion driver being merged into hid-uclogic; work done by Benjamin Tissoires and Nikolai Kondrashov - i2c-hid now supports ACPI GPIO interrupts; patch from Mika Westerberg - Some of the quirks, that got separated into individual drivers, have historically had EXPERT dependency. As HID subsystem matured (as well as the individual drivers), this made less and less sense. This dependency is now being removed by patch from Jean Delvare - Logitech lg4ff driver received a couple of improvements for mode switching, by Michal Malý - multitouch driver now supports clickpads, patches by Benjamin Tissoires and Seth Forshee - hid-sensor framework received a substantial update; namely support for Custom and Generic pages is being added; work done by Srinivas Pandruvada - wacom driver received substantial update; it now supports i2c-conntected devices (Mika Westerberg), Bamboo PADs are now properly supported (Benjamin Tissoires), much improved battery reporting (Jason Gerecke) and pen proximity cleanups (Ping Cheng) - small assorted fixes and device ID additions * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid: (68 commits) HID: sensor: Update document for custom sensor HID: sensor: Custom and Generic sensor support HID: debug: fix error handling in hid_debug_events_read() Input - mt: Fix input_mt_get_slot_by_key HID: logitech-hidpp: fix error return code HID: wacom: Add support for Cintiq 13HD Touch HID: logitech-hidpp: add a module parameter to keep firmware gestures HID: usbhid: yet another mouse with ALWAYS_POLL HID: usbhid: more mice with ALWAYS_POLL HID: wacom: set stylus_in_proximity before checking touch_down HID: wacom: use wacom_wac_finger_count_touches to set touch_down HID: wacom: remove hardcoded WACOM_QUIRK_MULTI_INPUT HID: pidff: effect can't be NULL HID: add quirk for PIXART OEM mouse used by HP HID: add HP OEM mouse to quirk ALWAYS_POLL HID: wacom: ask for a in-prox report when it was missed HID: hid-sensor-hub: Fix sparse warning HID: hid-sensor-hub: fix attribute read for logical usage id HID: plantronics: fix Kconfig default HID: pidff: support more than one concurrent effect ...

2015-04-10HID: sensor: Custom and Generic sensor supportSrinivas Pandruvada
HID Sensor Spec defines two usage ids for custom sensors HID_USAGE_SENSOR_TYPE_OTHER_CUSTOM (0x09, 0xE1) HID_USAGE_SENSOR_TYPE_OTHER_GENERIC(0x09, 0xE2) In addition the standard also defines usage ids for custom fields. The purpose of these sensors is to extend the functionality or provide a way to obfuscate the data being communicated by a sensor. Without knowing the mapping between the data and its encapsulated form, it is difficult for an driver to determine what data is being communicated by the sensor. This allows some differentiating use cases, where vendor can provide applications. Since these can't be represented by standard sensor interfaces like IIO, we present these as fields with - type (input/output) - units - min/max - get/set value In addition an dev interface to transfer report events. Details about this interface is described in /Documentation/hid/hid-sensor.txt. Manufacturers should not use these ids for any standard sensors, otherwise the the product/vendor id can be added to black list.

2015-04-10HID: debug: fix error handling in hid_debug_events_read()Jiri Kosina
In the unlikely case of hdev vanishing while hid_debug_events_read() was sleeping, we can't really break out of the case switch as with other cases, as on the way out we'll try to remove ourselves from the hdev waitqueue. Fix this by taking a shortcut exit path and avoiding cleanup that doesn't make sense in case hdev doesn't exist any more anyway.

2015-04-02HID: logitech-hidpp: add a module parameter to keep firmware gesturesBenjamin Tissoires
The Logitech T650 used to report 3 fingers swipes to the up as a press on the Super key. When we switched the touchpad to the raw mode, we also disable such firmware gesture and some users may rely on it. Unfortunately, 3 finger swipes are still not supported in most of the Linux environments, which means that we disabled a feature of the touchpad. Allow users to revert the raw reporting mode and keep going with the firmware gestures by providing a new module parameter.

2015-04-02HID: wacom: remove hardcoded WACOM_QUIRK_MULTI_INPUTPing Cheng
The quirk was added for devices that support both pen and touch. It decides if a device supports multiple inputs by hardcoded feature type. However, for some devices, we do not know if they support both before accessing their HID descriptors. This patch relies on dynamically assigned device_type to make the decision. Also, we make it certain that wacom_wac->shared is always created. That is, the driver will not be loaded if it fails to create wacom_wac->shared.

2015-03-16HID: wacom: ask for a in-prox report when it was missedBenjamin Tissoires
If noone listens to the input device when a tool comes in proximity, the tablet does not send the in-prox event when a client becomes available. That means that no events will be sent until the tool is taken out of proximity. In this situation, ask for the report WACOM_REPORT_INTUOSREAD which will read the corresponding feature and generate an in-prox event. To make some generation of hardware working, we need to unset the quirk NO_GET set by hid-core because the interfaces are seen as "boot mouse". We don't schedule this read in a worker while we are in an IO interrupt. We know that usbhid will do it asynchronously. If this is triggered by uhid, then this is obviously a client side bug :) Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Acked-by: Jason Gerecke <killertofu@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2015-03-16HID: hid-sensor-hub: fix attribute read for logical usage idSrinivas Pandruvada
For defining enumeration values like report or power status events, the enumeration usage ids are enclosed in a logical collection. In this case we need to match logical usage id for pending read on this usage id. For example, in the below field, when read is requested for 0319, the report will contain one of the status usages like 850, 851 etc. In this case the raw event will not match 0319. So when logical collection matches, then wake up the pending thread.

2015-03-16HID: pidff: support more than one concurrent effectJim Keir
The PID driver (usbhid/hid-pidff.c) does not set the effect ID when uploading an effect. The result is that the initial upload works but subsequent uploads to modify effect parameters are all directed at the last-created effect. The targeted effect ID must be passed back to the device when effect parameters are changed. This is done at the start of "pidff_set_condition_report", "pidff_set_periodic_report" etc. based on the value of "pidff->block_load[PID_EFFECT_ BLOCK_INDEX].value[0]". This value is only ever set during pidff_request_effect_upload. The result is stored in "pidff->pid_id[effect->id]" at the end of pid_upload_effect, for later use. However, if an effect is modified and re-sent then this identifier is not being copied back from pidff->pid_id[effect->id] before sending the command to the device. The fix is to do this at the start of pidff_upload_effect. Signed-off-by: Jim Keir <jimkeir@oracledbadirect.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2015-03-16HID: Stop hiding options with !EXPERTJean Delvare
Many HID driver options are hidden unless EXPERT is set. While I understand the idea of simplifying the kernel configuration for most users, in practice I believe it adds more confusion than it helps. One thing that worries me is that, in non-EXPERT mode, these drivers will be either built-in or modular based on apparent magic. For example, switching INPUT and HID from m to y will cause all these drivers to be built into the kernel when they were previously built as modules. Short of enabling EXPERT mode altogether, the user has no control over that. Generally I do not think tristate options should depend on !EXPERT. Of these, 11 of 15 are currently in the hid subsystem. The HID_LOGITECH option is even worse than the others. Sub-options depend on it, and this causes menuconfig and friends to display the option even though the user can't change its value. The help page for HID_LOGITECH will not explain why the value can't be changed. It only says, for example: Depends on: INPUT [=y] && HID [=y] and that leaves the user puzzled about why the option is forced to y. You might argue that this is a Kconfig bug, but that doesn't make it less annoying for the user. Even worse is that some of the sub-options of HID_LOGITECH select INPUT_FF_MEMLESS, which in turn gets out of control for the user. So, if you set INPUT=y and HID=y (something most general purpose distributions would do these days, as both modules would get loaded on a vast majority of systems otherwise), and you want support for force-feedback game controllers, you can't have that as a module, it has to be built-in, regardless of how rare these devices are. Of course, all this madness goes away once EXPERT is enabled, but then the rest of the kernel configuration becomes more complex, which totally voids the original point. For this reason, I would like all HID device tristate options to be displayed regardless of EXPERT being set or not. We can let the default settings still depend on EXPERT, that's not intrusive.

2015-03-13power_supply: Change ownership from driver to coreKrzysztof Kozlowski
Change the ownership of power_supply structure from each driver implementing the class to the power supply core. The patch changes power_supply_register() function thus all drivers implementing power supply class are adjusted. Each driver provides the implementation of power supply. However it should not be the owner of power supply class instance because it is exposed by core to other subsystems with power_supply_get_by_name(). These other subsystems have no knowledge when the driver will unregister the power supply. This leads to several issues when driver is unbound - mostly because user of power supply accesses freed memory. Instead let the core own the instance of struct 'power_supply'. Other users of this power supply will still access valid memory because it will be freed when device reference count reaches 0. Currently this means "it will leak" but power_supply_put() call in next patches will solve it. This solves invalid memory references in following race condition scenario: Thread 1: charger manager Thread 2: power supply driver, used by charger manager THREAD 1 (charger manager) THREAD 2 (power supply driver) ========================== ============================== psy = power_supply_get_by_name() Driver unbind, .remove power_supply_unregister() Device fully removed psy->get_property() The 'get_property' call is executed in invalid context because the driver was unbound and struct 'power_supply' memory was freed.

2015-03-13power_supply: Move run-time configuration to separate structureKrzysztof Kozlowski
Add new structure 'power_supply_config' for holding run-time initialization data like of_node, supplies and private driver data. The power_supply_register() function is changed so all power supply drivers need updating. When registering the power supply this new 'power_supply_config' should be used instead of directly initializing 'struct power_supply'. This allows changing the ownership of power_supply structure from driver to the power supply core in next patches. When a driver does not use of_node or supplies then it should use NULL as config. If driver uses of_node or supplies then it should allocate config on stack and initialize it with proper values.

2015-03-12HID: multitouch: Add support for button type usageSeth Forshee
According to [1], Windows Precision Touchpad devices must supply a button type usage in the device capabilities feature report. A value of 0 indicates that the device contains a depressible button (i.e. it's a click-pad) whereas a value of 1 indicates a non-depressible button. Add support for this usage and set INPUT_PROP_BUTTONPAD on the touchpad input device whenever a depressible button is present.

2015-03-11HID: wacom: Add battery presence indicator to wireless tabletsJason Gerecke
Declare the POWER_SUPPLY_PROP_PRESENT property to provide userspace with a way to determine if the battery on a wireless tablet is plugged in. Although current wireless tablets do not explicitly report this information, it can be inferred from other state information. In particular, a battery is assumed to be present if any of the following are true: a non-zero battery level reported, the battery is reported as charging, or the tablet is operating wirelessly. Note: The last condition above may not strictly hold for the Graphire Wireless (it charges from a DC barrel jack instead of a USB port), but I do not know what is reported in the no-battery condition.
