* HID: wacom: fix an Oops caused by wacom_wac_finger_count_touchesPing Cheng2015-05-20
| | | | | | | | | | We assumed all touch interfaces report touch data. But, Bamboo and Intuos non-touch devices report express keys on touch interface. We need to check touch_max before counting touches. Reported-by: Tasos Sahanidis <tasos@tasossah.com> Signed-off-by: Ping Cheng <pingc@wacom.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The stylus of this device works just fine out of the box. The touch is seen by default as a mouse with relative events and some gestures. The wireless and the wired version have slightly different firmwares, but the debug mode 2 on the feature 2 is common to the 2 devices. In this mode, all the reports are emitted through the debug interface (pen, raw touch and mouse emulation), so we have to re-route manually the events. We keep the Pen interface as a HID_GENERIC one because it works, and only parse the raw touches while discarding the mouse emulation & gestures. Switching the default in raw mode allows us to have a consistent user experience accross all the multitouch touchpads (and enable the touch part of the devices). Note that the buttons of this devices are reported through the touch interface. There is no 'Pad' interface. It seemed more natural to have the BTN_LEFT and BTN_RIGHT reported with the touch because they are placed under the touch interface and it looks like they belong to the touch part.

Traditionally both the stylus and pad shared the same device node, and xf86-input-wacom would use ABS_MISC for disambiguation.

Because these values are natively degree-based, we need to convert them to into units/radian as required by the input_absinfo struct. To ensure wraparound behaves properly for the rotation axes, the converted value was rounded up rather than rounded nearest. Notably, the touchring axes (ABS_WHEEL and ABS_THROTTLE) are left without a a declared resolution because the their low resolution cannot be accurately represented (the worst-case rounding-induced error would be ~16 degrees). Pre-scaling the values and range by at least 10x would reduce the error in the resolution to acceptable levels, but the xf86-input-wacom driver is not able to use pre-scaled values for these axes at this time.

* HID: wacom: implement generic HID handling for pen generic devicesBenjamin Tissoires2014-10-01
| | | | | | | | | | | | | | | | | | | | | | ISDv4 and v5 are plain HID devices. We can directly implement a generic HID parsing/handling and remove the need to manually add those PID in the list of supported devices. This patch implements the pen support only. The finger part will come in a later patch. To be properly notified of an .event() and a .report(), we need to force hid-core to go through the HID parsing. By default, wacom.ko binds only hidraw, so the hid parsing is not done by hid-core. When a true HID device is there, we add the flag HID_CLAIMED_DRIVER to hid->claimed which will force hid-core to parse the incoming reports. (Note that this can be easily backported by directly setting the .claimed flag to HID_CLAIMED_DRIVER even if hid-core does not support HID_CONNECT_DRIVER) Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Acked-by: Jason Gerecke <killertofu@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
* HID: wacom: make the WL connection friendly for the desktopBenjamin Tissoires2014-09-12
| | | | | | | | | | | | | | | | | | | Currently, tablets connected to the WL receiver all share the same VID/PID. There is no way for the user space to know which one is which besides parsing the name. We can force the PID to be set to the actual hardware. This way, the input device will have the correct PID which can be match in libwacom. With only this trick, the pad input does not inherit the ID_INPUT_TABLET udev property from its parent. We can force udev to accept it by declaring a BTN_STYLUS which is never used. This way, tablets connected through WL can be used from the user point of view in the same way they are used while connected through wire.

* Input: wacom - handle Intuos 4 BT in wacom.koBenjamin Tissoires2014-08-06
| | | | | | | | | | | A good point of this change is that now, the Intuos4 bluetooth can handle the different tools (artpen, airbrush, mice), and we get a common interface between USB and BT for accessing the LEDs/OLEDs.
