* Input: serio_raw - ensure we don't block in non-blocking readDmitry Torokhov2012-04-211-18/+25
| | | | | | | | | | | | | Avoid calling wait_event_interruptible() if client requested non-blocking read, since it is not guaranteed that another thread will not consume event after we checked if serio_raw->head != serio_raw->tail. Also ensure we do not return 0 but keep waiting instead in blocking case, when another thread steals "our" byte.

* Input: wacom - create inputs when wireless connectChris Bagwell2012-03-264-10/+109
| | | | | | | | | | | | | | | | | | | | When a tablet connect or disconnect is detected, schedule work queue to register or unregister related input devices. When a wireless tablet connects, it reports same USB PID used if tablet is connected with USB cable. Use this to update features values, set input capabilities, and then register device. From there, the Pen and Touch interfaces will reuse the existing tablet's IRQ routines. Its possible that 1 receiver is shared with 2 tablets with different PID (small and medium Bamboo for example) so the input is unregister at disconnect to better support this case.

* Input: wacom - wireless monitor frameworkChris Bagwell2012-03-263-6/+62
| | | | | | | | | | | | | | | | | | | | | | | The 3rd gen Bamboo Pen & Touch and Intuos5 tablets support an optional wireless module. When its receiver is plugged into USB, it presents 3 interfaces: 0) Monitor 1) Pen and 2) Touch. The exact capabilities of the Pen and Touch interfaces can not be determined until a tablet connection is established and reported over the Monitor interface. This patch detects this wireless receiver and enables interrupt packets to be processed for the Monitor interface. Processing the data in packets will be left to another patch. Since it doesn't make sense to create an input device for the Monitor interface, it is not created. Creation of Pen and Touch input device is also delayed until monitor packets can be processed.

| | | | | | | | | | | | | | | | | | - Hooking multi-finger coordinates output with kernel multitouch library; - Enabling absolute coordinates output for Cx+ hardware. The older hardware performs much better in relative mode; thus relative mode related code are preserved. Part of the code is based on the work done by Oskari Saarenmaa <os@ohmu.fi>, which was used to support the clickpad found on ASUS UX21/31 Ultrabook. On the other hand, the FSP found on UX21/31 doesn't have hardware capability register other than PnP ID, which means that we'll have to figure out an alternative approach to identify such pad correctly; otherwise, blindly adding INPUT_PROP_BUTTONPAD property may compatability issues amongst existing FSPs.
