HID: multitouch: fix maxcontacts problem on GeneralTouch

2012-10-31T09:42:32+00:00

Fix maxcontacts problem for PWT GeneralTouch multi-touchscreen.

Our device didn't contain HID_DG_CONTACTMAX usage. This usage use to describe
touchscreen's maxcontacts for hid-multitouch.c to get maxcontacts automatic. We
fix the device that driver can get maxcontact from our device, hence it doesn't
need .maxcontact=10. Now there is just one device class can fix all our PWT
touchscreen.

HID: hid-multitouch: Fix contact count on 3M panels

2012-09-19T17:50:21+00:00

Some devices report the number of contacts via the unreliable
CONTACTCOUNT usage, rather than using the CONTACTMAX feature.
Without this patch, the 3M devices are constrained to the default
maximum of ten fingers.

HID: hid-multitouch: Remove the redundant touch state

2012-09-19T17:50:20+00:00

With the input_mt_sync_frame() function in place, there is no longer
any need to keep the full touch state in the driver. This patch
removes the slot state and replaces the lookup code with the input-mt
equivalent.

HID: hid-multitouch: Simplify setup and frame synchronization

2012-09-19T17:50:20+00:00

With the input_configured() callback in place, the setup and frame
synchronization can be simplified. The input device initialization is
moved to mt_input_configured(), to make sure the full HID report has been
seen.

HID: multitouch: Add ELAN production request when resume.

2012-08-15T09:37:27+00:00

Add ELAN production request when resume.

Some Elan legacy devices require SET_IDLE to be set on resume.
It should be safe to send it to other devices too.
Tested on 3M, Stantum, Cypress, Zytronic, eGalax, and Elan panels.
