* 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

* If writing the control register fails, bail out without attaching any sensors.kettenis2016-05-121-1/+5
| | | | | From Marcus Glocker, who has an Apple G5 machine where an advertised sensor isn't there, and plodding on creates annoying dmesg spam.
* Print a meaningful interrupt string for i2c devices.kettenis2016-04-232-4/+6
|
* 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@

| | | | | | | | to the "Windows Precision Touchpad" standard. when a compatible device is found, hidmt claims all report ids and switches the device into multitouch packet mode. add imt, an i2c-HID driver that sits between ihidev and hidmt

* Several fixes for dwiic(4).kettenis2016-01-141-10/+10
| | | | | | | | | | | | | * Properly map bus space; using BUS_SPACE_MAP_PREFATCHABLE is not agood idea as it may lead to reordering or merging of register writes in the store buffer. * Properly implement the iic(4) operations in dwiic_i2c_exec(). * Keep timings set up by the firmware if the SSCN and FMCN methods aren't available. ok jcs@

* Don't confuse the HID descriptor address (which really is an office into thekettenis2016-01-132-4/+6
| | | | | | | | | register space of the i2c device) with the i2c address. For i2c busses enumerated by ACPI we get the address from the I2C Serial Bus Connection Resource Descriptor returned by the _CRS methide of the i2c device. Pass the HID descriptor address in the ia_size member. ok jcs@

* Add dwiic, a driver for the Synopsys DesignWare i2c controller foundjcs2016-01-125-2/+894
| | | | | | | | | | | | | 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
* Acquire/release the i2c bus before/after reading the temperature register.kettenis2015-05-301-3/+4
| | | | | | | Prevents concurrent access to the smu(4) microcontroller on Apple G5 machines, which would result in errors reading the RTC. ok deraadt@, mpi@

* Implement support for "clock stretching" where a slave device pulls down SCLkettenis2013-04-201-1/+32
| | | | | | to slow down the master device. This makes the i2c bit-banging code work with slow slave device such as SDVO chips and DDC eeproms found on various graphics hardware supported by inteldrm(4). Mostly from NetBSD.

| | | | | | | | i2c bit-banging code. Requires us to move around the i2c_bitbang define. Also move the onewire_bitbang define to be close to i2c_bitbang since they are similar. ok jsing@
