2014-03-31Input: wacom - make sure touch_max is set for touch devicesPing Cheng
commit 1d0d6df02750b4a6f466768cbfbf860e24f4c8d4 upstream. Old single touch Tablet PCs do not have touch_max set at wacom_features. Since touch device at lease supports one finger, assign touch_max to 1 when touch usage is defined in its HID Descriptor and touch_max is not pre-defined.

2013-01-23Input: wacom - fix wacom_set_report retry logicChris Bagwell
Logic sets a value and then reads it back to make sure it worked and retries write on failures. Since read and write share a buffer, it needs to be set back up before writing though. Issue is not seen a lot because 1) it doesn't need to retry for a lot of tablets and 2) a lot of failures that need a retry are from an -ETIMEDOUT and hopefully buffer is not touched in this case. At least one user has shown logs with buffer being modified during -ETIMEDOUT case with linux 3.7 kernel.

2013-01-06Input: wacom - prepare for syncing with input-mt changesPing Cheng
Henrik added new MT routines in release 3.7. This patch is to prepare for the use of new MT routines. In the newly added wacom_abs_set_axis() function, the first if-statement assigns ABS_X/Y for number of contacts less or equal to 2. So, it is single and 2 finger touch devices. Two finger touch devices are processed here since they will not use the updated input_mt_init_slots(), which does not offer benefit to those devices. input_mt_init_slots() will take care of ABS_X/Y assignment when flags are not zero. All touch devices with more than two contacts will use input_mt_init_slots() with non-zero flags. The second if-statement is for all MT devices, which include two finger touch devices.

2012-10-25Input: wacom - handle split-sensor devices with internal hubsJason Gerecke
Like our other pen-and-touch products, the Cintiq 24HD touch needs data to be shared between its two sensors to facilitate proximity-based palm rejection. Unlike other tablets that report sensor data through separate interfaces of the same USB device, the Cintiq 24HD touch has separate USB devices that are connected to an internal USB hub. This patch makes it possible to designate the USB VID/PID of the other device so that the two may share data. To ensure we don't accidentally link to a sensor from a physically separate device (if several have been plugged in), we limit the search to siblings (i.e., devices directly connected to the same hub).

2012-10-04Input: wacom - introduce wacom_fix_phy_from_hidJason Gerecke
The Cintiq 24HD touch cannot use wacom_set_phy_from_res to determine the physical size of the touch sensor since the pen and touch are on separate USB devices. The physical size is, however, provided in the HID descriptor, just scaled to a unit we don't use. This patch introduces the function wacom_fix_phy_from_hid to let us make use of the unit and exponent data provided by HID to set the [xy]_phy variables to an appropriate value. This function relies on a trimmed-down version of hidinput_calc_abs_res from the hid-input.c.

2012-10-03Input: wacom - report correct touch contact size for I5/BambooJason Gerecke
This changes how the touch packets for Intuos5 and 3rd-gen Bamboo are interpreted, so that proper values for the MAJOR and MINOR axes are reported. Instead of using the amplitude field (data[6]), we use the size field (data[5]) and do some calculation to transform it from a scaled-down area into axis lengths. Note that even though we assume a circular contact, both MAJOR and MINOR are reported since the resolution of the X and Y axes differ.

2012-09-28Input: wacom - mark Intuos5 pad as in-prox when touching buttonsJason Gerecke
If the ExpressKeys on the Intuos5 are touched, they currently result an out-of-prox packet being sent even if the pad is already out of prox. This can cause some confusion in the X driver. To restore the expected semantics, we make being touched a sufficient condition to signal proximity. https://bugs.freedesktop.org/show_bug.cgi?id=54250 Reported-by: Timo Aaltonen <tjaalton@ubuntu.com> Signed-off-by: Jason Gerecke <killertofu@gmail.com> Reviewed-by: Chris Bagwell <chris@cnpbagwell.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
