Bluetooth connections may contain more than one set of touches, or a partial set of touches, in one report. Set the number of expected touches when reading a collection instead of once per report (in the pre-report function). Accordingly, reset the number of touches expected after each sync.

Finger data is separated into chunks in our Bluetooth report, where each report contains the same number of chunks. Those chunks are not aligned in any particular way to a set of finger touches. That is, the first half of a group of simultaneous touches may be in one chunk at the end of a report and the second half could be at the beginning of the next report. Also some chunks contain no data and potentially some chunks could contain leftover (bad) data. Introduce and process the WACOM_HID_WT_REPORT_VALID usage that the device uses to let us know if we should process a chunk of data.

In the generic code path, HID_DG_CONTACTMAX was previously only read from the second byte of report 0x23. Another report (0x82) has the HID_DG_CONTACTMAX in the higher nibble of the third byte. We should support reading the value of HID_DG_CONTACTMAX no matter what report we are reading or which position that value is in. To do this we submit the feature report as a event report using hid_report_raw_event(). Our modified finger event path records the value of HID_DG_CONTACTMAX when it sees that usage.

The existing INTUOSP2_BT device class supports LEDs and this device does not. A new device class enum entry, "INTUOSP2S_BT", is created to avoid the INTUOSP2_BT LED code.

Currently, the driver will attempt to set the mode on all devices with a center button, but some devices with a center button lack LEDs, and attempting to set the LEDs on devices without LEDs results in the kernel error message of the form: "leds input8::wacom-0.1: Setting an LED's brightness failed (-32)" This is because the generic codepath erroneously assumes that the BUTTON_CENTER usage indicates that the device has LEDs, the previously ignored TOUCH_RING_SETTING usage is a more accurate indication of the existence of LEDs on the device.

Pull HID updates from Jiri Kosina: - support for U2F Zero device, from Andrej Shadura - logitech-dj has historically been treating devices behind non-unifying receivers as generic devices, using the HID emulation in the receiver. That had several shortcomings (special keys handling, battery level monitoring, etc). The driver has been reworked to enumarate (and directly communicate with) the devices behind the receiver, to avoid the (too) generic HID implementation in the receiver itself. All the work done by Benjamin Tissoires and Hans de Goede. - restructuring of intel-ish driver in order to allow for multiple clients of the ISH implementation, from Srinivas Pandruvada - several other smaller fixes and assorted device ID additions * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/hid/hid: (68 commits) HID: logitech-dj: fix spelling in printk HID: input: fix assignment of .value HID: input: make sure the wheel high resolution multiplier is set HID: logitech-dj: add usbhid dependency in Kconfig HID: logitech-hidpp: add support for HID++ 1.0 consumer keys reports HID: logitech-hidpp: add support for HID++ 1.0 extra mouse buttons reports HID: logitech-hidpp: add support for HID++ 1.0 wheel reports HID: logitech-hidpp: make hidpp10_set_register_bit a bit more generic HID: logitech-hidpp: add input_device ptr to struct hidpp_device HID: logitech-hidpp: do not hardcode very long report length HID: logitech-hidpp: handle devices attached to 27MHz wireless receivers HID: logitech-hidpp: use RAP instead of FAP to get the protocol version HID: logitech-hidpp: remove unused origin_is_hid_core function parameter HID: logitech-hidpp: remove double assignment from __hidpp_send_report HID: logitech-hidpp: do not make failure to get the name fatal HID: logitech-hidpp: ignore very-short or empty names HID: logitech-hidpp: make .probe usbhid capable HID: logitech-hidpp: allow non HID++ devices to be handled by this module HID: logitech-dj: add support for Logitech Bluetooth Mini-Receiver HID: logitech-dj: make appending of the HID++ descriptors conditional ...

Specifics: - Convert the ACPI documentation in the kernel source tree to the .rst format and split it into the admin guide, driver API and firmware guide parts (Changbin Du). - Add a PRP0001 usage example to the ACPI documentation (Thomas Preston). - Switch over the users of the acpi_dev_get_first_match_name() library function which turned out to be problematic to a new, better one called acpi_dev_get_first_match_dev() (Andy Shevchenko, YueHaibing). - Update the ACPICA code in the kernel to upstream release 20190405 including: * Null pointer dereference check in acpi_ns_delete_node() (Erik Schmauss). * Multiple macro and function name changes (Bob Moore). * Predefined operation region name fix (Erik Schmauss). - Fix hibernation issue on systems using the Baytrail and Cherrytrail Intel SoCs introduced during the 4.20 development cycle (Hans de Goede). - Add Sony VPCEH3U1E to the backlight quirk list (Zhang Rui). - Fix button handling during system resume (Zhang Rui). - Add a device PM diagnostic message (Rafael Wysocki). - Clean up the code, comments and white space in multiple places (Bjorn Helgaas, Gustavo Silva, Kefeng Wang)" * tag 'acpi-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (53 commits) Documentation: ACPI: move video_extension.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move ssdt-overlays.txt to admin-guide/acpi and convert to reST Documentation: ACPI: move lpit.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move cppc_sysfs.txt to admin-guide/acpi and convert to reST Documentation: ACPI: move apei/einj.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move apei/output_format.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move aml-debugger.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move method-tracing.txt to firmware-guide/acpi and convert to rsST Documentation: ACPI: move debug.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move dsd/data-node-references.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move dsd/graph.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move acpi-lid.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move i2c-muxes.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move dsdt-override.txt to admin-guide/acpi and convert to reST Documentation: ACPI: move initrd_table_override.txt to admin-guide/acpi and convert to reST Documentation: ACPI: move method-customizing.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move gpio-properties.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move DSD-properties-rules.txt to firmware-guide/acpi and covert to reST Documentation: ACPI: move scan_handlers.txt to driver-api/acpi and convert to reST Documentation: ACPI: move linuxized-acpica.txt to driver-api/acpi and convert to reST ...
