HID: hid-multitouch: fix wrong protocol detection

2012-07-16T16:04:28+00:00

commit 3ac36d15557d1bedfb1151d9911b9587b2d40759 upstream.

The previous implementation introduced a randomness in the splitting
of the different touches reported by the device. This version is more
robust as we don't rely on hi->input->absbit, but on our own structure.

This also prepares hid-multitouch to better support Win8 devices.

HID: multitouch: add PID for Fructel product

2012-03-20T12:17:22+00:00

Adds multitouch support for the Gametel Android game controller.

The multitouch events are emulated by the Gametel device. Each physical button
is configured to generate a MT event on a specific coordinate. This seems to be
the only way for us to support Android games that doesn't support HID gamepads.
It is possible to inject MT events at Android level, but this requires root on
the phone.

HID: multitouch: detect serial protocol

2012-03-12T11:50:27+00:00

Microsoft's documentation about multitouch protocols tells that
if a device presents one touch per report, then it should be treated
as a serial protocol.

HID: handle all multitouch devices through hid-multitouch

2012-03-12T10:27:07+00:00

When the quirk HID_QUIRK_MULTITOUCH is present and when hid-multitouch
is loaded, let's pass the device to hid-multitouch even if it has
not been registered in hid-multitouch.

If any other driver wants to take precedence over hid-multitouch,
the usual way of adding it to hid_have_special_driver will work as
the quirk HID_QUIRK_MULTITOUCH won't be set by the generic hid layer.

HID: multitouch: fix handling of buggy reports descriptors for Dell ST2220T

2012-03-12T10:23:55+00:00

LG multitouch panels, such as the one found in Dell ST2220T, has buggy
reports descriptors. With the previous implementation, it was impossible
to rely on the reports descriptors to determine how the different
touches are emitted from the device.

This patch changes the splitting of the different touches in the report
in a more robust way.

HID: multitouch: add more eGalax devices

2012-03-06T13:09:24+00:00

This is a list of devices that should be handled by hid-multitouch.  They all
present the HID usage "Contact ID" and won't be handled by hid-input.  Some of
them have _not_ been tested (though I have their report descriptors), but I've
been guaranted by eeti that they follow the same protocol.  The tested ones are
also blacklisted in hid-core.c.
