* Move HID->bus constant conversion for HID report types out of ihidevjcs2018-08-253-14/+7
| | | | | | | | | | | | | | | | | | | | | 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

* I2C driver for the Maxim DS1307 Real Time Clock chip.mglocker2016-06-202-1/+301
| | | | | | | | | | | | The chip has been found on a Sun Fire V210 as a second RTC hooked up to the SMU. Setting the time there has the advantage that it remains after a boot since the internal V210 RTC will be synced by the DS1307 at boot time. Not linked to sparc64 yet since it will overwrite the internal RTC handler. ok deraadt

* Fix layer violation in the ihidev(4) code by implementing a generic mechanismkettenis2016-04-102-23/+17
| | | | | | | | | | 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@
