While investigating bug https://bugzilla.kernel.org/show_bug.cgi?id=37982 , there was solid evidences that Microsoft reused the same report descriptor for the its Digital Media keyboard series. Since 1989dad "HID: input: ignore System Control application usages if not System Controls", the keyboard series do not produce a spurious joystick input device inode without needing to patch the problematic report descriptor. As such the MS_RDESC_3K reportdescriptor fixup can be removed. Signed-off-by: Michel Hermier <michel.hermier@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

While libinput and other stacks don't care that much (we can detect them), joydev is very happy and attaches itself to the mouse or keyboard. The problem is that joydev now handles the device as a joystick, but given that we have a HID array, it sets all the ABS_* values to 0. And in its world, 0 means -32767 (minimum value), which sends spurious events to games (think Steam). It looks like hid-microsoft tries to tackle the very same problem with its .report_fixup callback. But fixing the report descriptor is an endless task and is quite obfuscated. So take the hammer, and decide that if the application is meant to be System Control, any other usage not in the System Control range should be ignored.

| | * / HID: alps: fix multitouch cursor issueMasaki Ota2016-09-271-6/+6

Cause: We do not notify multi fingers state correctly to input subsystem. For example, when three fingers release from Touchpad, fingers state is 3 -> 0. It needs to notify first, second and third finger's releasing state. Fix this by not breaking out on z axis and move x,y,z input handling code to the correct place so that it's in fact per-finger.

This can cause the report processing code to get tripped up and send an incorrect event stream to userspace. In particular, this can cause last_slot_field to be overwritten with the result that the driver prematurely assumes it has finished processing a slot and sending the ABS_MT_SLOT event at the wrong point in time, associating events for the current contact with the following contact instead. To prevent this from occurring, we update the value of last_slot_field durring the pre_report phase to ensure that it is correct for the report that is to be processed.

| * HID: migrate USB LED driver from usb misc to hidHeiner Kallweit2016-06-175-3/+306
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch migrates the USB LED driver to the HID subsystem. Supported are Dream Cheeky Webmail Notifier / Friends Alert and Riso Kagaku Webmail Notifier. Benefits: - Avoid using USB low-level calls and use the HID subsystem instead (as this device provides a USB HID interface) - Use standard LED subsystem instead of proprietary sysfs entries, this allows e.g. to use the device with features like triggers Successfully tested with a Dream Cheeky Webmail Notifier and a Riso Kagaku Webmail Notifier compatible device.

| | | * | | HID: uhid: fix timeout when probe races with IORoderick Colenbrander2016-06-011-9/+24
| | | | |/ | | | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many devices use userspace bluetooth stacks like BlueZ or Bluedroid in combination with uhid. If any of these stacks is used with a HID device for which the driver performs a HID request as part .probe (or technically another HID operation), this results in a deadlock situation. The deadlock results in a 5 second timeout for I/O operations in HID drivers, so isn't fatal, but none of the I/O operations have a chance of succeeding. The root cause for the problem is that uhid only allows for one request to be processed at a time per uhid instance and locks out other operations. This means that if a user space is creating a new HID device through 'UHID_CREATE', which ultimately triggers '.probe' through the HID layer. Then any HID request e.g. a read for calibration data would trigger a HID operation on uhid again, but it won't go out to userspace, because it is still stuck in UHID_CREATE. In addition bluetooth stacks are typically single threaded, so they wouldn't be able to handle any requests while waiting on uhid. Lucikly the UHID spec is somewhat flexible and allows for fixing the issue, without breaking user space. The idea which the patch implements as discussed with David Herrmann is to decouple adding of a hid device (which triggers .probe) from UHID_CREATE. The work will kick off roughly once UHID_CREATE completed (or else will wait a tiny bit of time in .probe for a lock). A HID driver has to call HID to call 'hid_hw_start()' as part of .probe once it is ready for I/O, which triggers UHID_START to user space. Any HID operations should function now within .probe and won't deadlock because userspace is stuck on UHID_CREATE. We verified this patch on Bluedroid with Android 6.0 and on desktop Linux with BlueZ stacks. Prior to the patch they had the deadlock issue.

Some HW design (i.e. Umaro, a chromebook model) is that the power to i2c hid device won't down after device shutdown. Also the i2c-hid driver do not send suspend cmd to the hid i2c device and free its irq before shutdown.So if We touch the touchscreen or some other i2c hid device, the power consumtion will be go up even when the device is in shutdown state. Though the root cause maybe a HW issue. But it seems that it is a good pratice to set power sleep for i2c-hid device before shutdown.

| | |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | i2c-hid devices' suspend/resume are usually time-consuming process. For example, the touch controller(i2c-ATML1000:00) on ASUS T100 tablet takes about 160ms for suspending and 120ms for resuming. This patch enables i2c-hid devices to suspend/resume asynchronously. This will take advantage of multicore and speed up system suspend/resume process.
