HID: hid-goodix: Add Goodix HID-over-SPI driver

2024-08-19T19:14:39Z

This patch introduces a new driver to support the Goodix GT7986U touch controller. This device is not compatible with Microsoft's HID-over-SPI protocol and therefore needs to implement its own flavor. The data reported is packaged according to the HID protocol but uses SPI for communication to improve speed. This enables the device to transmit not only coordinate data but also corresponding raw data that can be accessed by user-space programs through the hidraw interface. The raw data can be utilized for functions like palm rejection, thereby improving the touch experience. Key features: - Device connection confirmation and initialization - IRQ-based event reporting to the input subsystem - Support for HIDRAW operations (GET_REPORT and SET_REPORT) Reviewed-by: Dmitry Torokhov Signed-off-by: Charles Wang Signed-off-by: Jiri Kosina

HID: uclogic: Avoid linking common code into multiple modules

2024-06-19T14:33:10Z

The hid-uclogic-params.o and hid-uclogic-rdesc.o files are linked into both the driver module and the unit test, which triggers a W=1 warning: scripts/Makefile.build:236: drivers/hid/Makefile: hid-uclogic-rdesc.o is added to multiple modules: hid-uclogic hid-uclogic-test scripts/Makefile.build:236: drivers/hid/Makefile: hid-uclogic-params.o is added to multiple modules: hid-uclogic hid-uclogic-test Avoids this by moving these two files into a separate module that is used by the driver and the unit test.

HID: Add WinWing Orion2 throttle support

2024-04-03T11:35:44Z

WinWing Orion2 throttle works with Linux out of box, but the kernel sees only 16 of 47 buttons on the throttle base. This module enables all buttons, and also adds LED controls. Button numbers 0 .. 63 on Orion2 are reserved for throttle grip; the throttle base buttons have numbers 64 .. 110. Linux kernel HID subsystem only supports up to 80 buttons. Remap throttle base buttons to numbers 32 .. 78, reserving only numbers 0 .. 31 for buttons on the grip handle. Changes since v2: - Fixed automatic line wraps added by mail client Changes since v1: - Fixed formatting of descriptor byte array; - Using product codes of Winwing grips in config.

HID: mcp2200: added driver for GPIOs of MCP2200

2023-11-21T08:27:18Z

Added a gpiochip compatible driver to control the 8 GPIOs of the MCP2200 by using the HID interface. Using GPIOs with alternative functions (GP0<->SSPND, GP1<->USBCFG, GP6<->RXLED, GP7<->TXLED) will reset the functions, if set (unset by default). The driver was tested while also using the UART of the chip. Setting and reading the GPIOs has no effect on the UART communication. However, a reset is triggered after the CONFIGURE command. If the GPIO Direction is constantly changed, this will affect the communication at low baud rates. This is a hardware problem of the MCP2200 and is not caused by the driver.

HID: hid-google-stadiaff: add support for Stadia force feedback

2023-08-14T09:35:37Z

Add a hid-google-stadiaff module to support rumble based force feedback on the Google Stadia controller. This works using the HID output endpoint exposed on both the USB and BLE interface. Signed-off-by: Fabio Baltieri Reviewed-by: Rahul Rameshbabu Signed-off-by: Jiri Kosina

Merge branch 'for-6.3/hid-bpf' into for-linus

2023-02-22T09:44:31Z

Initial support of HID-BPF (Benjamin Tissoires) The history is a little long for this series, as it was intended to be sent for v6.2. However some last minute issues forced us to postpone it to v6.3. Conflicts: * drivers/hid/i2c-hid/Kconfig: commit bf7660dab30d ("HID: stop drivers from selecting CONFIG_HID") conflicts with commit 2afac81dd165 ("HID: fix I2C_HID not selected when I2C_HID_OF_ELAN is") the resolution is simple enough: just drop the "default" and "select" lines as the new commit from Arnd is doing

HID: evision: Add preliminary support for EVision keyboards

2023-02-06T17:17:56Z

For now only supports one model and only filters out bogus reports sent when the keyboard has been configured through hidraw. Without this, as events are not released, soft repeat floods userspace with unknown key events.

HID: initial BPF implementation

2022-11-15T15:28:28Z

Declare an entry point that can use fmod_ret BPF programs, and also an API to access and change the incoming data. A simpler implementation would consist in just calling hid_bpf_device_event() for any incoming event and let users deal with the fact that they will be called for any event of any device. The goal of HID-BPF is to partially replace drivers, so this situation can be problematic because we might have programs which will step on each other toes. For that, we add a new API hid_bpf_attach_prog() that can be called from a syscall and we manually deal with a jump table in hid-bpf. Whenever we add a program to the jump table (in other words, when we attach a program to a HID device), we keep the number of time we added this program in the jump table so we can release it whenever there are no other users. HID devices have an RCU protected list of available programs in the jump table, and those programs are called one after the other thanks to bpf_tail_call(). To achieve the detection of users losing their fds on the programs we attached, we add 2 tracing facilities on bpf_prog_release() (for when a fd is closed) and bpf_free_inode() (for when a pinned program gets unpinned).
