* On some laptops that have a Windows Precision Touchpad (imt) andjcs2020-07-091-7/+12
| | | | | | | | | | | also a trackstick or separate physical buttons, imt was claiming all report ids of the ihidev device preventing the trackstick/buttons from attaching as a separate ims device on other report ids. Just claim the report ids that imt needs and let ims attach to others it may find. Fixes two Dell Latitude laptops and tested in snaps for a bit.

* Even when polling is requested, install ihidev's interrupt handlerjcs2019-07-221-7/+62
| | | | | | | | If an interrupt is received, turn off polling and rely on interrupts. This may happen after S3 resume. Also properly shut down polling during suspend and start it up again on resume only after dwiic is back in action.

* Move HID->bus constant conversion for HID report types out of ihidevjcs2018-08-251-12/+3
| | | | | | | | | | | | | | | | | | | | | into hidmt. The HID code uses hid_feature, hid_input, and hid_output constants to refer to report types internally that then need to be converted to their bus-level counterparts before actually getting sent out (so hid_feature becomes UHID_FEATURE_REPORT for USB, I2C_HID_REPORT_TYPE_FEATURE for i2c). This conversion was hard-coded in ihidev but ihidev_[gs]et_report should assume the type passed is already an i2c-level define, not a hid one. This is how uhidev does it. Add a conversion routine callback that any hidmt callers need to set so that hidmt can convert hid constants to the bus-level versions. Also add a similar conversion function to uhidev. ok deraadt

* Fix layer violation in the ihidev(4) code by implementing a generic mechanismkettenis2016-04-101-19/+8
| | | | | | | | | | that allows the i2c controller implementation to establish interrupts on behalf of i2c slave device drivers. Use this mechanism in dwiic(4) to let it configure the right acpi interrupt (global or gpio). Change the level to IPL_TTY as this is the appropriate level to use for keyboards and other input devices. ok jsg@

on the Samsung ATIV Book 9 laptop. This initial version only supports ACPI config/attachment. Add ihidev, a HID-over-i2c driver largely based on uhidev. dwiic handles attaching ihidev devices found in ACPI. Add ims, a HID-over-i2c mouse/trackpad driver to get basic cursor and button functionality from HID-compliant i2c trackpads. ok kettenis deraadt
