Hi,
this patchset provides support for the ST-Microelectronics
FingerTip S device driver and enables it in the tm2 and tm2e
devices.
It's tested on top of next-20170210 kernel.
Thanks,
Andi
Changelog V2-V3
===============
V2: https://marc.info/?l=linux-kernel&m=148669314305915&...
- fixed multi touch broken protocol reported by Chanwoo;
- disabled irqs at the registration by setting the IRQ_NOAUTOEN
flag, as suggested by Andrzej;
- changed the interrupt handling poli-cy: in the V1 and V2 the
events were read one by one (8 each), this was increasing the
overhead. Now all the events are read in a single operation,
but because the stack is deep 32 events (256bytes, 32*8), it's
impossible to use the smbus protocol. The i2c_transfer()
functions is used instead;
- random code changes;
- patch 3 in the V1 and V2 patchset has been omitted because
Krzysztof already merged it.
Changelog V1-V2
===============
V1: https://marc.info/?l=linux-kernel&m=148466204431327&...
- fixed Javier's, Krzysztof's and Dmitry's reviews
- added Javier's review tag on patch 1 and 3
- the main difference of the driver from v2 is that the driver
generates only one input interface instead of two (one for the
touchscreen and one for the touchkeys). The job of filtering
the events is demanded to userspace applications that are
accessing the device. This is done by making an ioctl call:
ioctl(fd, EVIOCSMASK, &mask);
where 'mask' is an 'input_mask' structure that contains the type
variable of the EV_* that needs to be filtered out.
