| * | HID: sony: support for ghlive ps3/wii u donglesPascal Giard2020-11-273-0/+116
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | HID: sony: Don't use fw_version/hw_version for sysfs cleanup.Roderick Colenbrander2020-11-251-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DS4 dongle reports fw_version and hw_version as 0 when no actual DS4 is connected to it. This prevents cleaning up sysfs nodes upon device remove. This patch decouples sysfs cleanup from the fw_version and hw_version values by introducing boolean values.

| * | HID: sony: Report more accurate DS4 power status.Roderick Colenbrander2020-11-251-35/+50
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the power supply status logic to DS3/DS4 parse_report, to allow for more accurate DS4 status reporting. The DS4 power status code was actually incorrect, but reported okay'ish data in most cases. There was a different interpretation of the battery_info values 0-10 or 0-9 depending on cable state. It added +1 to extend the range to 0-10. This is actually incorrect, there is no different range. Values higher than 11 actually indicates 'full' and 14/15 'error' for which we reported 100% and a valid power state. Moving the status logic to parse_report avoids having to pass more state to the generic sony_battery_get_property and simplifies the code.

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The report descriptor for EX-G wireless mouse (M-XGL20DLBK) is a bit different from that for trackball mice such as DEFT. For such mouse, the current `mouse_button_fixup` cannot be used as is, because it uses hard-coded indices for a report descriptor. Add parameters to `mouse_button_fixup` function, in order to support fixing report descriptors for more models.

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.

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.

The connect/disconnect logic works fine generally, however not in conjunction with Steam. Steam implements its own DS4 driver using hidraw. Both hid-sony and Steam are issuing their own HID requests and are racing each other during DS4 dongle connect/disconnect resulting in a kernel crash in hid-sony. The problem is that upon a DS4 connect to the dongle, hid-sony kicks of 'ds4_get_calibration_data' from within its dongle hotplug code. The calibration code issues raw HID feature report for reportID 0x02. When Steam is running, it issues a feature report for reportID 0x12 typically just prior to hid-sony requesting feature reportID 0x02. The result is that 'ds4_get_calibration_data' receives the data Steam requested as that's the HID report returing first. Currently this results in it processing invalid data, which ultimately results in a divide by zero upon a future 'dualshock4_parse_report'. The solution for now is to check within 'ds4_get_calibration_data' to check if we received data for the feature report we issued and if not retry. This fixes bug 206785.

In this case when asking the receiver for paired devices, we get only 1 paired device with a device_type of REPORT_TYPE_KEYBOARD. This means that we do not instantiate a second dj_hiddev for the mouse (as we normally would) and thus there is no place for us to forward the mouse input reports to, causing the touchpad part of the keyboard to not work. There is no way for us to detect these keyboards, so this commit adds an array with device-ids for such keyboards and when a keyboard is on this list it adds STD_MOUSE to the reports_supported bitmap for the dj_hiddev created for the keyboard fixing the touchpad not working. Using a list of device-ids for this is not ideal, but there are only very few such keyboards so this should be fine.

In those cases, the report ID in struct hid_report will be zero and the data for the report will start at the first byte, so don't skip over the first byte.

* | | | | | HID: i2c-hid: Put ACPI enumerated devices in D3 on shutdownHans de Goede2020-10-291-0/+9

Specifically, the i2c_smbus_read_byte() "Make sure there is something at this address" check would fail every other boot. It seems that the BIOS does not properly reset/power-cycle the device leaving it in a confused state where it refuses to respond to i2c-xfers. On boots where probing the device failed, the driver-core puts the device in D3 after the probe-failure, which causes the probe to succeed the next boot. Putting the device in D3 from the shutdown-handler fixes the sensors not working every other boot. This has been tested on both a Lenovo Miix 2-10 and a Dell Venue 8 Pro 5830 both of which use an i2c-hid sensor-hub with an ACPI id of SMO91D0. Note that it is safe to call acpi_device_set_power() with a NULL pointer as first argument, so on none ACPI enumerated devices this change is a no-op.
