Protect concurrent access to output HID report with a spinlock. The HID report structure used to submit commands to wheels is shared amongst all functions that need to do so and some of these functions can be executed in parallel. Additionally, lg4ff_play() can be called from interrupt context by ff-memless module. Locking is necessary to prevent sending bogus data to the wheels.

2015-05-07Revert "HID: logitech-hidpp: support combo keyboard touchpad TK820"Benjamin Tissoires
This reverts commit 3a61e97563d78a2ca10752902449570d8433ce76. The Logitech TK820 seems to be affected by a firmware bug which delays the sending of the keys (pressed, or released, which triggers a key-repeat) while holding fingers on the touch sensor. This behavior can be observed while using the mouse emulation mode if the user moves the finger while typing (highly improbable though). Holding the finger still while in the mouse emulation mode does not trigger the key repeat problem. So better keep things in their previous state to not have to explain users that the new key-repeat bug they see is a "feature". Furthermore, I noticed that I disabled the media keys whith this patch. Sorry, my bad. I think it is best to revert the patch, in all the current versions it has been shipped.

2015-05-04HID: wacom: Fail probe if HID_GENERIC device has unknown device_typeJason Gerecke
The last patch was careful to maintain backwards-compatible behavior by forcing device_type to BTN_TOOL_PEN (and printing a warning) if it were still uninitialized after scanning the HID descriptor and applying quirks. We should be more strict with HID_GENERIC devices, however, since there is no a priori guarantee that it is a tablet or touchpad. If the device_type is still uninitialized for a HID_GENERIC device then we assume that it isn't something the driver can work with and so fail the probe.

2015-05-04HID: wacom: Discover device_type from HID descriptor for all devicesJason Gerecke
Currently, we assume a device_type of BTN_TOOL_PEN before scanning the HID descriptor and then change the device_type if what we discover proves that assumption wrong. This way of doing things makes it more difficult to figure out if a device (particularly a HID_GENERIC device) actually does tablet/touch input or is something completley different. This patch leaves device_type at its initial value of 0 and then calls 'wacom_parse_hid' for every device (not just those that have touch). As we map the usages, we can set the device_type as before. After we're finished, we can then check if the value is still zero and do whatever is most appropriate. Detecting the pen can be a little tricky on most Wacom devices because the descriptors describe opaque blobs. Fortunately, older Wacom tablets have the HID_DG_DIGITIZER usage on the pen's application collection and newer tablets seem to have a similar vendor-defined usage that we can trigger on.

2015-05-04HID: wacom: Do not add suffix to name of devices with an unknown typeJason Gerecke
The naming logic currently assumes that all devices will be a pen, finger, or pad. Though this has historically been the case, the new HID_GENERIC catch-all may cause us to probe devices with Wacom's 056A VID which aren't any of these types (e.g. the "Cintiq 24HDT Monitor Control"). This patch updates the logic so that no suffix will be added to the device name if the device type is unknown.

2015-04-27HID: wacom: retrieve name from HID descriptor for generic devicesPing Cheng
HID generic devices share the same default name, "Wacom HID". This causes userland programs to show same device names for different devices, which would confuse end users with same device names for different devices too. This patch uses name retrieved from HID descriptor, if a meaningful name is reported. Otherwise, affix its product ID to "Wacom HID". Names from descriptor may contain extra whitespaces. To comfort readers' eyes, we removed those extra whitespaces too.

The raphnet.net 4nes4snes and 2nes2snes multi-joystick adapters use a single HID report descriptor with one report ID per controller. This has the effect that the inputs of otherwise independent game controllers get packed in one large joystick device. With this patch each controller gets its own /dev/input/jsX device, which is more natural and less confusing than having all inputs going to the same place.

However, commit a485923efbb8 ("HID: i2c-hid: Add support for ACPI GPIO interrupts") did not take into account that acpi_dev_add_driver_gpios() returns -ENXIO when !CONFIG_GPIOLIB.

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.
