2021-02-09HID: logitech-dj: add support for the new lightspeed connection iterationFilipe Laíns
This new connection type is the new iteration of the Lightspeed connection and will probably be used in some of the newer gaming devices. It is currently use in the G Pro X Superlight. This patch should be backported to older versions, as currently the driver will panic when seing the unsupported connection. This isn't an issue when using the receiver that came with the device, as Logitech has been using different PIDs when they change the connection type, but is an issue when using a generic receiver (well, generic Lightspeed receiver), which is the case of the one in the Powerplay mat. Currently, the only generic Ligthspeed receiver we support, and the only one that exists AFAIK, is ther Powerplay. As it stands, the driver will panic when seeing a G Pro X Superlight connected to the Powerplay receiver and won't send any input events to userspace! The kernel will warn about this so the issue should be easy to identify, but it is still very worrying how hard it will fail :( [915977.398471] logitech-djreceiver 0003:046D:C53A.0107: unusable device of type UNKNOWN (0x0f) connected on slot 1 Signed-off-by: Filipe Laíns <lains@riseup.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2021-02-05HID: logitech-dj: add support for keyboard events in eQUAD step 4 GamingFilipe Laíns
In e400071a805d6229223a98899e9da8c6233704a1 I added support for the receiver that comes with the G602 device, but unfortunately I screwed up during testing and it seems the keyboard events were actually not being sent to userspace. This resulted in keyboard events being broken in userspace, please backport the fix. The receiver uses the normal 0x01 Logitech keyboard report descriptor, as expected, so it is just a matter of flagging it as supported.

2021-02-02HID: google: Get HID report on probe to confirm tablet switch stateNicolas Boichat
This forces reading the base folded state anytime the device is probed, to make sure it's in sync. This is useful after a reboot, if the device re-enumerates for any reason (e.g. ESD shock), or if the driver is unbound/rebound (debugging/testing). Without this, the tablet switch state is only synchronized after a key is pressed (since the device would then send a report that includes the switch state), leading to strange UX (e.g. UI mode changes when a key is pressed after reboot). This is not a problem on detachable base attach, as the device, by itself, sends a report after it is booted up.

2021-02-02HID: hid-input: avoid splitting keyboard, system and consumer controlsDmitry Torokhov
A typical USB keyboard usually splits its keys into several reports: - one for the basic alphanumeric keys, modifier keys, F<n> keys, six pack keys and keypad. This report's application is normally listed as GenericDesktop.Keyboard - a GenericDesktop.SystemControl report for the system control keys, such as power and sleep - Consumer.ConsumerControl report for multimedia (forward, rewind, play/pause, mute, etc) and other extended keys. - additional output, vendor specific, and feature reports Splitting each report into a separate input device is wasteful and even hurts userspace as it makes it harder to determine the true capabilities (set of available keys) of a keyboard, so let's adjust application matching to merge system control and consumer control reports with keyboard report, if one has already been processed.

2021-01-26HID: wacom: Correct NULL dereference on AES pen proximityJason Gerecke
The recent commit to fix a memory leak introduced an inadvertant NULL pointer dereference. The `wacom_wac->pen_fifo` variable was never intialized, resuling in a crash whenever functions tried to use it. Since the FIFO is only used by AES pens (to buffer events from pen proximity until the hardware reports the pen serial number) this would have been easily overlooked without testing an AES device. This patch converts `wacom_wac->pen_fifo` over to a pointer (since the call to `devres_alloc` allocates memory for us) and ensures that we assign it to point to the allocated and initalized `pen_fifo` before the function returns.

2021-01-18HID: i2c-hid: Reorganize so ACPI and OF are separate modulesDouglas Anderson
This patch rejiggers the i2c-hid code so that the OF (Open Firmware aka Device Tree) and ACPI support is separated out a bit. The OF and ACPI drivers are now separate modules that wrap the core module. Essentially, what we're doing here: * Make "power up" and "power down" a function that can be (optionally) implemented by a given user of the i2c-hid core. * The OF and ACPI modules are drivers on their own, so they implement probe / remove / suspend / resume / shutdown. The core code provides implementations that OF and ACPI can call into. We'll organize this so that we now have 3 modules: the old i2c-hid module becomes the "core" module and two new modules will depend on it, handling probing the specific device. As part of this work, we'll remove the i2c-hid "platform data" concept since it's not needed.

2021-01-18HID: logitech-hidpp: add support for Unified Battery (1004) featureFilipe Laíns
This new feature present in new devices replaces the old Battery Level Status (0x1000) feature. It keeps essentially the same information for levels (reporting critical, low, good and full) but makes these levels optional, the device exports a capability setting which describes which levels it supports. In addition to this, there is an optional state_of_charge paramenter that exports the battery percentage. This patch adds support for this new feature. There were some implementation choices, as described below and in the code. If the device supports the state_of_charge parameter, we will just export the battery percentage and not the levels, which the device might still support. Since this feature can co-exist with the Battery Voltage (0x1001) feature and we currently only support one battery feature, I changed the battery feature discovery to try to use 0x1000 and 0x1004 first and only then 0x1001, the battery voltage feature. In the future we could uncouple this and make the battery feature co-exists with 0x1000 and 0x1004, allowing the device to export voltage information in addition to the battery percentage or level. I tested this patch with a MX Anywhere 3, which supports the new feature. Since I don't have any device that doesn't support the state_of_charge parameter of this feature, I forced the MX Anywhere 3 to use the level information, instead of battery percentage, to test that part of the implementation. I also tested with a MX Master 3, which supports the Battery Level Status (0x1000) feature, and a G703 Hero, which supports the Battery Voltage (0x1001) feature, to make sure nothing broke there.

2021-01-18HID: make arrays usage and value to be the sameWill McVicker
The HID subsystem allows an "HID report field" to have a different number of "values" and "usages" when it is allocated. When a field struct is created, the size of the usage array is guaranteed to be at least as large as the values array, but it may be larger. This leads to a potential out-of-bounds write in __hidinput_change_resolution_multipliers() and an out-of-bounds read in hidinput_count_leds(). To fix this, let's make sure that both the usage and value arrays are the same size.

From Sandeep Singh. AMD SFH (Sensor Fusion Hub) is HID based driver.SFH FW is part of MP2 processor (MP2 which is an ARM core connected to x86 for processing sensor data) and it runs on MP2 where in the driver resides on X86. The driver functionalities are divided into three parts: 1: amd-mp2-pcie:- This part of the module will communicate with MP2 firmware. MP2 which is exposed as a PCI device to the X86, uses mailboxes to talk to MP2 firmware to send/receive commands. 2: Client Layer:- This part of the driver will use DRAM data and convert the data into HID format based on HID reports. 3: Transport layer :- This part of the driver the will communicate with HID core.Communication between devices and HID core is mostly done via HID reports In terms of architecture, it resembles like ISH (Intel Integrated Sensor Hub). However the major difference is all the hid reports are generated as part of the kernel driver. AMD SFH is integrated as a part of SoC, starting from 17h family of processors. The solution is working well on several OEM products. AMD SFH uses HID over PCIe bus.

Make the hid-ite driver handle the Acer S1002 keyboard-dock, this leads to 2 improvements: 1. The non working wifi-toggle hotkey now works. 2. Toggling the touchpad on of with the hotkey will no show OSD notifications in e.g. GNOME3. The actual toggling is handled inside the keyboard, this adds support for notifying evdev listeners about this.

2020-11-27HID: sony: support for ghlive ps3/wii u donglesPascal Giard
This commit adds support for the Guitar Hero Live PS3 and Wii U dongles. These dongles require a "magic" USB control message [1] to be sent approximately every 10 seconds otherwise the dongle will not report events where the strumbar is hit while a fret is being held. Also, inspired by a patch sent on linux-input by Sanjay Govind [2], the accelerometer is mapped to ABS_RY for tilt. Interestingly, the Wii U and PS3 dongles share the same VID and PID.

2020-11-27HID: hidraw: Add additional hidraw input/output report ioctls.Dean Camera
Currently the hidraw module can only read and write feature HID reports on demand, via dedicated ioctls. Input reports are read from the device through the read() interface, while output reports are written through the write interface(). This is insufficient; it is desirable in many situations to be able to read and write input and output reports through the control interface to cover additional scenarios: - Reading an input report by its report ID, to get initial state - Writing an input report, to set initial input state in the device - Reading an output report by its report ID, to obtain current state - Writing an output report by its report ID, out of band This patch adds these missing ioctl requests to read and write the remaining HID report types. Note that not all HID backends will neccesarily support this (e.g. while the USB link layer supports setting Input reports, others may not). Also included are documentation and example updates. The current hidraw documentation states that feature reports read from the device does *not* include the report ID, however this is not the case and the returned report will have its report ID prepended by conforming HID devices, as the report data sent from the device over the control endpoint must be indentical in format to those sent over the regular transport.

2020-11-25HID: mf: add support for 0079:1846 Mayflash/Dragonrise USB Gamecube AdapterEthan Warth
Mayflash/Dragonrise seems to have yet another device ID for one of their Gamecube controller adapters. Previous to this commit, the adapter registered only one /dev/input/js* device, and all controller inputs (from any controller) were mapped to this device. This patch defines the 1846 USB device ID and enables the HID_QUIRK_MULTI_INPUT quirk for it, which fixes that (with the patch, four /dev/input/js* devices are created, one for each of the four controller ports).
