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&w=2 - 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 policy: 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&w=2 - 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.
