Hi Guys,
here is the forth version of this patchset.
* patches 1-9 has already been reviewed and are ready for inclusion I would say.
* Jiri, I kept your ack on patch 4 even if I changed the place of the comment in hid.h
* patch 10 is half new as it is splitted from a patch of the v3
* patch 11 has been changed according to Henrik's comments
* patches 12-13 have been splitted since v3 to introduce QUIRK_HOVERING and setup WIN 8
devices in a better way.
* patch 14 has been copied from the v3 as Dmitry wanted to use a MSC event for the timestamp.
Cheers,
Benjamin
v1 introduction:
So, this is an update for supporting Win 8 multitouch devices in the kernel.
As I wanted to reliably forward the resolution, I noticed a bug in the
processing of the unit_exponent in the hid core layer.
Thus the fixes for hid-core and hid-input.
v2 changes:
* added missing initial patch that prevents the series to be applied on top of Jiri's tree
* update to include latest hid changes
* taken into account Alan's patch: "hid: put the case in the right switch statement"
v3 changes:
* splitted "round return value of hidinput_calc_abs_res" in a separate patch
* export snto32 in hid.h as we need to use it in hid-input.c
* didn't change all drivers, but add a field in hid_usage instead
* add quirk MT_QUIRK_IGNORE_DUPLICATES so that any device can rely on it
* easier understandable support of hovering devices
* changed scan time definition
* applied new definition of scan time in hid-multitouch
* some other few things.
v4 changes:
* introduced QUIRK_HOVERING for hovering devices (not necessarily win 8 ones)
* removed QUIRK_WIN8_CERTIFIED as it's not relevant anymore
* made the change in input-mt.c
* add a test against input->mt != null
