| * | HID: multitouch: remove registered devices with default behaviorBenjamin Tissoires2014-03-051-118/+11Star
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default multitouch protocol class in use since the kernel v3.9 is working quite well. Since its inclusion, the only devices we had to tweak were those who really need quirks (GeneralTouch, FocalTech and Wistron, the 3 of them are Win 7 certified ones). The flow of new unhandled devices has stopped, which is great and I think it's time to reduce the list of registered device. This commit removes only the registration in the kernel of devices that use the class MT_CLS_DEFAULT, or that can use it. By that, I mean that I checked all the recordings I have, and the produced input device and events are the same before and after applying the patch. This gives two benefits: - remove a bunch of lines of codes - prevent bad handling of existing registered devices which are using a different protocol while using the same VID/PID (I got the case of a Quanta 3008 recently). I also removed the associated classes (MT_CLS*). I kept their #define in case people use the new_id sysfs node with a non standard class (their should be really few people now, but we never now). This is why there are /* reserved .... */. Last, I add a comment on top of mt_devices[] definition to remember people (and myself) not to include devices for the beauty of it. To people still trying to add devices with the default class: """ Guys, try out your device under a kernel greater or equal to v3.9. If it works, you are all set. Adding your VID/PID to the kernel only brings us overload and you won't get anything from it _because_ even a backport of this shiny patch will _not_ make the device work under 3.0, 3.2, 3.4 or even 3.8. So if it works, it works. If it does not work, then yes, submit a patch or call for help. In any cases, if you want me to do regression tests, I'd be happy to get some traces of your device. But I won't patch the kernel if it works. """ Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

* HID: do not init input reports for Win 8 multitouch devicesBenjamin Tissoires2013-08-271-0/+12
| | | | | | | | | | | | | | | | | Some multitouch screens do not like to be polled for input reports. However, the Win8 spec says that all touches should be sent during each report, making the initialization of reports unnecessary. The Win7 spec is less precise, so do not use this for those devices. Add the quirk HID_QUIRK_NO_INIT_INPUT_REPORTS so that we do not have to introduce a quirk for each problematic device. This quirk makes the driver behave the same way the Win 8 does. It actually retrieves the features, but not the inputs.
