* Input: wacom - Bamboo One 1024 pressure fixChris Bagwell2012-08-151-1/+1
| | | | | | | | | | | | | | | | | | | | | commit 6dc463511d4a690f01a9248df3b384db717e0b1c upstream. Bamboo One's with ID of 0x6a and 0x6b were added with correct indication of 1024 pressure levels but the Graphire packet routine was only looking at 9 bits. Increased to 10 bits. This bug caused these devices to roll over to zero pressure at half way mark. The other devices using this routine only support 256 or 512 range and look to fix unused bits at zero.

* Input: wacom - report resolution for pen devicesPing Cheng2011-03-261-92/+179
| | | | | | | | | | | | Touch resolution is reported to the userland by retrieving the value from the HID descriptor. But pen resolution is not since it can not be retrieved. The current Wacom X driver has a resolution table. To centralize the source of these values, the resolution entries are added in the wacom_features struct for x and y coordinates respectively. The values are then reported to the userland. Signed-off-by: Ping Cheng <pingc@wacom.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

* Input: wacom - support one finger touch the touchscreen wayPing Cheng2011-03-121-90/+49
| | | | | | | | | | | | | | | | | | | | There are two types of 1FGT devices supported in wacom_wac.c. Changing them to follow the existing touchscreen format, i.e., only report BTN_TOUCH as a valid tool type. Touch data will be ignored if pen is in proximity. This requires a touch up event sent if touch was down when pen comes in. The touch up event should be sent before any pen events are emitted. Otherwise, two pointers would race for the cursor. However, we can not send a touch up inside wacom_tpc_pen since pen and touch are on different logical port. That is why we have to check if touch is up before sending pen events.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The drivers using the type B protocol all report tracking information the same way. The contact id is semantically equivalent to ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates the driver. The situation can be improved upon by providing a common pointer emulation code, thereby removing the need for the tracking id in the driver. This patch moves all tracking event handling over to the input core, simplifying both the existing drivers and the ones currently in preparation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The Bamboo Touch reports a sub-screen resolution of 480x320. The signal-to-noise ratio is only about 100, so filtering is needed in order to reduce the jitter to a usable level. However, the low resolution leads to round-off errors in the EWMA filter, resulting in extremely jerky pointer motion. This patch explicitly sets a higher resolution for those devices, and tells this to the completion handler via a low-resolution quirk.

* Input: wacom - fix mousewheel handling for old wacom tabletsMike Auty2010-08-281-2/+2
| | | | | | | | | | | | | | | | | | This fixes a regression introduced in 3b57ca0f80c5c8994b5b1e3d3f904cfe727951f2. The data[6] byte contains either 1 or -1 depending on the whether the mouse wheel on older wacom tablets is moved down (1) or up (-1). The patch introduced in the above commit changed the cast from (signed char) to (signed). When cast as a signed integer and negated, the value of -1 (stored in the byte as 0xff) became -255 rather than 1. This patch reverts the cast to a (signed char) and also removes an unnecessary (signed) cast, as all the values operated on are bitmasked.

| | | | | | | | | | | | | | | | Touch enbaled devices share the same product ID with pen. However, we do not want to post touch events while pen is in prox. To do so, we used to keep a local static variable to keep track of if pen is in prox or not. This works fine for Tablet PC devices since there is only one device attached. With the newer touch enabled regular tablets, we can not make this assumption any more, i.e, one system may have more than one identical tablet plugged in. This patch adds an new entry, shared, into the struct wacom_wac so touch data can access pen data to locally. This solution assumes the two tools (touch and pen) of the same ID will be probed one after the other without interruption in between by another Wacom device of the same ID.
