| * Input: wacom - update the ABI doc according to latest changesBenjamin Tissoires2014-08-071-43/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now the devices show up under hid no matter the connection (for USB and Bluetooth, not serial nor i2c). The USB devices can now be easily found under /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n> The Bluetooth devices could also be found under this path since their inclusion (April 2010), so this patch fixes the non-precise "hidraw*" path for them. The ABI has been unified while setting the LEDs and OLEDs. So Bluetooth devices lost their own LED selector but use the USB sysfs attribute. For OLEDs, Bluetooth devices handle only 1-bit images instead of 4 for USB. The documentation has been updated to match this.

These are called siblings in the code. The current way of implementation relies on the USB topology to be able to share data amongs those sensors. We can replace the code to match a HID subsystem, without involving the USB topology: - the first probed sensor does not find any siblings in the list wacom_udev_list, so it creates its own wacom_hdev_data with its own struct hid_device - the other sensor checks the current list of siblings in wacom_hdev_data, and if there is a match, it associates itself to the matched device. To be sure that we are not associating different sensors from different physical devices, we also check for the phys path of the hid device which contains the USB topology.

For historical reasons, they are handled as plain USB devices. The current code makes more and more reference to the HID subsystem like implementing its own HID report descriptor parser to handle new devices. From the user point of view, we can transparently switch from this state to a driver handled in the HID subsystem and clean up a lot of USB specific code in the wacom.ko driver. The other benefit once the USB dependecies have been removed is that we can use a tool like uhid to make regression tests and allow further cleanup or new implementations without risking breaking current behaviors. To match the current handling of devices in wacom_wac.c, we rely on the hid_type set by usbhid. usbhid sets the hid_type to HID_TYPE_USBMOUSE when it sees a USB boot mouse protocol declared and HID_TYPE_USBNONE when the device is plain HID. There is thus a one to one matching between the list of supported devices before and after the switch from USB to HID.

| | | * Input: wacom - create a separate input device for padsBenjamin Tissoires2014-07-254-9/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the pad events are sent through the stylus input device for the Intuos/Cintiqs, and through the touch input device for the Bamboos. To differentiate the buttons pressed on the pad from the ones pressed on the stylus, the Intuos/Cintiq uses MISC_SERIAL and ABS_MISC. This lead to a multiplexing of the events into one device, which are then splitted out in xf86-input-wacom. Bamboos are not using MISC events because the pad is attached to the touch interface, and only BTN_TOUCH is used for the finger (and DOUBLE_TAP, etc...). However, the user space driver still splits out the pad from the touch interface in the same way it does for the pro line devices. The other problem we can see with this fact is that some of the Intuos and Cintiq have a wheel, and the effective range of the reported values is [0..71]. Unfortunately, the airbrush stylus also sends wheel events (there is a small wheel on it), but in the range [0..1023]. From the user space point of view it is kind of difficult to understand that because the wheel on the pad are quite common, while the airbrush tool is not. A solution to fix all of these problems is to split out the pad device from the stylus/touch. This decision makes more sense because the pad is not linked to the absolute position of the finger or pen, and usually, the events from the pad are filtered out by the compositor, which then convert them into actions or keyboard shortcuts. For backward compatibility with current xf86-input-wacom, the pad devices still present the ABS_X, ABS_Y and ABS_MISC events, but they can be completely ignored in the new implementation.

It is unnecessary to change the configuration of any other objects (for example to disable T9 touchscreen). It is counterproductive to reset the chip on resume, it will result in a long delay. However it is necessary to issue a calibrate command after the chip has spent any time in deep sleep. This patch also deals with the situation where the power configuration is zero on probe, which would mean that the device never wakes up to execute commands.
