Revert "HID: multitouch: decide if hid-multitouch needs to handle mt devices"

2011-11-01T14:26:31+00:00

This reverts commit 0db3bfc72adf0c (""HID: multitouch: decide if hid-multitouch
needs to handle mt devices").

The generic detection of hid-mt devices has two major flaws, and was
merged prematurely. Firstly, the hid-multitouch gets loaded even when
the device is handled by a special device. Secondly, the patch only
partially duplicates the device whitelist already present in hid-core,
effectively rendering a number of devices non-functional.

HID: multitouch: decide if hid-multitouch needs to handle mt devices

2011-09-26T12:19:02+00:00

Now that hid-generic ignores all win7 compatible multitouch devices, this patch
allows hid-multitouch to catch them.  The idea is to rely on the quirk
HID_QUIRK_MULTITOUCH to drop the device if no ContactID is given.

There is the need for a blacklist here as other devices may need a special
driver (ntrig for instance).

HID: hid-multitouch: add support for the IDEACOM 6650 chip

2011-09-20T13:14:30+00:00

The IDEACOM 6650 multitouch chip, present in various all-in-one computers,
uses the serial version of the HID multitouch protocol. No existing class
supports this.

In principle, the new MT_CLS_SERIAL should work for other
serial panels as well, perhaps including some eGalax panels.

HID: hid-multitouch: Filter collections by application usage.

2011-08-16T09:38:44+00:00

This change fixes two problems.

First, it ensures that the hid-multitouch driver does not incorrectly
map GenericDesktop usages that are intended for other applications,
such as a Mouse.

Second, it sets the appropriate input properties so that user-space
can distinguish TouchScreen devices (INPUT_PROP_DIRECT) from
TouchPad devices (INPUT_PROP_POINTER) and configure them accordingly.

HID: hid-multitouch: ensure slots are initialized

2011-06-24T11:39:51+00:00

In case a device does not provide the feature "Maximum Contact Count",
or set it at 0, the maxcontacts field may be at 0 while calling
input_mt_init_slots.

This patch ensures that hid-multitouch will allways report
ABS_MT_SLOT and ABS_MT_TRACKING_ID to the user space.

This corrects a bug found with some Ilitek devices that has been
integrated in 3.0-rc0.
