* Add atopcase, the Apple HID over SPI input driverVal Packett2023-08-201-0/+1
| | | | | | | | | | | | | | | | The driver provides support for Human Interface Devices (HID) on Serial Peripheral Interface (SPI) buses on Apple Intel Macs produced in 2015-2018. The driver appears to work more stable after installation of Darwin OSI in acpi(4) driver. To install Darwin OSI insert following lines into /boot/loader.conf: hw.acpi.install_interface="Darwin" hw.acpi.remove_interface="Windows 2009, Windows 2012" Reviewed by: wulf Differential revision: https://reviews.freebsd.org/D39863

| | | | | | | | | | | hid_ioctl method executes arbitrary transport backend command. Format of the command is defined by hardware transport driver. It is intended to assist HID device drivers to execute non-HID commands on hybrid devices like Elan and Apple touchpads which can be switched between HID and proprietary modes. MFC after: 2 month

* newbus: Move from bus_child_{pnpinfo,location}_src to ↵Warner Losh2021-06-231-9/+8
| | | | | | | | | | | | | | | | | | | | | | bus_child_{pnpinfo,location} with sbuf Now that the upper layers all go through a layer to tie into these information functions that translates an sbuf into char * and len. The current interface suffers issues of what to do in cases of truncation, etc. Instead, migrate all these functions to using struct sbuf and these issues go away. The caller is also in charge of any memory allocation and/or expansion that's needed during this process. Create a bus_generic_child_{pnpinfo,location} and make it default. It just returns success. This is for those busses that have no information for these items. Migrate the now-empty routines to using this as appropriate. Document these new interfaces with man pages, and oversight from before. Reviewed by: jhb, bcr Sponsored by: Netflix Differential Revision: https://reviews.freebsd.org/D29937

* hid: Import usbhid - USB transport backend for HID subsystem.Vladimir Kondratyev2021-01-071-0/+1
| | | | | | | | | | | | | | | | This change implements hid_if.m methods for HID-over-USB protocol [1]. Also, this change adds USBHID_ENABLED kernel option which changes device_probe() priority and adds/removes PnP records to prefer usbhid over ums, ukbd, wmt and other USB HID device drivers and vice-versa. The module is based on uhid(4) driver. It is disabled by default for now due to conflicts with existing USB HID drivers.

| | | | | | | | | | | | | | | | | This implements hid_if.m methods for HID-over-I2C protocol [1]. Following kernel options are added: IICHID_SAMPLING - Enable support for a sampling mode as interrupt resource acquisition is not always possible in a case of GPIO interrupts. IICHID_DEBUG - Enable debug output. The module is based on prior Marc Priggemeyer work (D16698).

* hid: Import hidbus(4)Vladimir Kondratyev2021-01-071-0/+905
This driver provides support for multiple HID driver attachments to single HID transport backend. This ability existed in Net/OpenBSD (uhidev and ihidev drivers) but has never been ported to FreeBSD. Unlike Net/OpenBSD we do not use report number alone to distinct report source but we follow MS way and use a top level collection (TLC) usage index that report belongs to as a location key. The driver performs child device autodiscovery based on HID report descriptor data, proxying of HID requests from child devices to parent transport backends and broadcasting of interrupts in backward direction.
