| | | | | | | | | | always matched on an FDT-capable device, but the HoneyComb LX2K seems to have a PCA9547 and provides it as NXP0002 HID. This means we know if it's ACPI or FDT based on the name passed. This is required to be able to make two acpitz(4) nodes work, since the thermel sensors are behind the mux. ok kettenis@

| | | | | | | | the PCA954[68], this is a mux instead of a switch and can only have one active channel at a time. On the bright side, we treat switches like a mux, so only the bits have to be set a little bit differently. ok kettenis@

| | | | | | | | | | | platforms than just loongson. Rename it to mfokrtc(4) for consistency with other RTC drivers. Make it match on st,m41t83, since that was the chip for which the driver was written for. More compatible strings can be added for each chip of the series verified to behave the same.

* The pcamux(4) device tree node's children are the individual channels,patrick2020-09-291-2/+4
| | | | | | | | which we each treat as an I2C bus. While scanning these, we need to use each channel's node as starting point instead of the pcamux(4) node. This fixes finding and attaching devices connected to these channels. ok kettenis@

| | | | | | | | | | | 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.

| | | | | | | | | | being too clever trying to use the SMBus block reads/writes. Instead the registers were written with an offset: Seconds were stored in the minutes, minutes were stored in the hours. No wonder time was ticking so slowly. Removing the bogus length field and simply writing/reading the time register values is enough. ok kettenis@

* 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
