This patch fixes three problems with the eGalax/DWAV multi-touch screen found in the Eee PC T101MT: 1) While there is a dedicated multitouch driver for the screen (hid-egalax.c), the MULTI_INPUT quirk is also applied, preventing the hid-egalax driver from working. This patch removes the quirk so the hid-egalax driver can handle the device correctly. 2) The x and y coordinates sent by the screen in multi-touch mode are shifted by three bits from the events sent in single-touch mode, thus the coordinates are out of range, leading to the pointer being stuck in the bottom-right corner if no additional calibration is applied (e.g. in the X evdev driver). This patch shifts the coordinates back. This does not decrease accuracy as the last three bits of the "wrong" coordinates are always 0. 3) Only multi-touch pressure events are sent, single touch emulation is missing pressure information. This patch adds single-touch ABS_PRESSURE events. Signed-off-by: Philipp Merkel <mail@philmerk.de> Acked-by: Stéphane Chatty <chatty@enac.fr> Signed-off-by: Jiri Kosina <jkosina@suse.cz> |
