2012-04-21Input: synaptics - fix regression with "image sensor" trackpadsBenjamin Herrenschmidt1-1/+2
commit 7968a5dd492ccc38345013e534ad4c8d6eb60ed1 Input: synaptics - add support for Relative mode Accidentally broke support for advanced gestures (multitouch) on some trackpads such as the one in my ThinkPad X220 by incorretly changing the condition for enabling them. This restores it. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> CC: stable@kernel.org [3.3] Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2012-04-12Input: da9052 - fix memory leak in da9052_onkey_probe()Jesper Juhl1-1/+2
If, in drivers/input/misc/da9052_onkey.c::da9052_onkey_probe(), the call to either kzalloc() or input_allocate_device() fails then we will return -ENOMEM from the function without freeing the other allocation that may have succeeded, thus we leak either the memory allocated for 'onkey' or the memory allocated for 'input_dev' if one succeeds and the other fails. Fix that by jumping to the 'err_free_mem' label at the end of the function that properly cleans up rather than returning directly.

Add pointer and buttonpad properties for v4 hardware. Also, Jachiet reported that on Asus UX31, right button has no effect. It turns out v4 has only one button, the right-button effect is implemented with software when Windows driver is installed, or in firmware when touchpad is in relative mode. So remove BTN_RIGHT while at it.

2012-04-10Input: elantech - reset touchpad before configuring itJJ Ding1-0/+4
Acer VH40 has a Fn key toggling the touchpad on and off, but it's implemented in system firmware, and the EC chip has to receive reset command to activate this function. Also when this machine wakes up after resume, psmouse_reset is necessary to bring the touchpad back on.

2012-04-03Input: sentelic - filter taps in absolute modeOskari Saarenmaa1-0/+8
Taps in absolute positioning single-finger mode are currently reported as physical clicks by the driver. This should be handled by userspace, not the kernel. When a tap occurs, the FSP_PB0_LBTN bit is set, but the FSP_PB0_PHY_BTN is not. We use this to filter out physical clicks from taps.

2012-03-26Input: wacom - create inputs when wireless connectChris Bagwell4-10/+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.

2012-03-26Input: wacom - wireless monitor frameworkChris Bagwell3-6/+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.

2012-03-26Input: sentelic - enabling absolute coordinates output for newer hardwareTai-hwa Liang2-4/+132
- 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.

Several fixes based on customer feedback: * WHO_AM_I value has changed since preliminary parts used for initial testing; * Output of le16_to_cpu must be saved to memory before shifting to preserve sign; * Initial data rate was not extracted from data control register init. This was causing the initial data rate to be set to maximum until it was changed. To fix this problem, it made more sense to specify initial data rate and extract the register mask from that.
