2022-06-13HID: surface-hid: Add support for hot-removalMaximilian Luz
Add support for hot-removal of SSAM HID client devices. Once a device has been hot-removed, further communication with it should be avoided as it may fail and time out. While the device will be removed as soon as we detect hot-removal, communication may still occur during teardown, especially when unregistering notifiers. While hot-removal is a surprise event that can happen at any time, try to avoid communication as much as possible once it has been detected to prevent timeouts that can slow down device removal and cause issues, e.g. when quickly re-attaching the device.

2022-06-09HID: multitouch: new device class fix Lenovo X12 trackpad stickyTao Jin
The trackpad of the given device sends continuous report of pointers status as per wxn8 spec. However, the spec did not clarify when the fingers are lifted so fast that between the interval of two report frames fingers on pad reduced from >=2 to 0. The second last report contains >=2 fingers with tip state 1 and the last report contains only 1 finger with tip state 0. Although this can happen unfrequently, a quick fix will be improve the consistency to 100%. A quick fix is to disable MT_QUIRK_ALWAYS_VALID and enable MT_QUIRK_NOT_SEEN_MEANS_UP. Test for hid-tools is added in [1] In addition to this, I2C device 04CA:00B1 may also need similar class but with MT_QUIRK_FORCE_MULTI_INPUT disabled (but it does not harm to enable it on non-multi-input device either).

2022-06-08HID: i2c-hid: elan: Add support for Elan eKTH6915 i2c-hid touchscreensDouglas Anderson
Like many i2c-hid touchscreen controllers, the Elan eKTH6915 has a reset GPIO hooked up to it. According to the datasheet, the way we're supposed to turn the touchscreen on is: 1. Turn on the 3.3V supply. 2. Turn on the IO supply. It's OK if this is hardwired to the 3.3V supply, but if it's not then it must be turned on _after_ the 3.3V supply. 3. Wait >= 1 ms. 4. Deassert the reset GPIO (reset GPIO is active low, so there would be a leakage path if this was deasserted _before_ the IO supply). 5. Wait 300 ms. Much of the above can be handled by the generic i2c-hid-of driver, but the "reset" GPIO is not supported by that driver. Thus we'll do the same as we did for Goodix and add a new tiny driver that uses the i2c-hid core. NOTE: support for this new touchscreen could theorically fit into the Goodix driver. I've made it a separate driver because the Elan driver supports _two_ regulators and it's unclear exactly how that would fit in with commit 18eeef46d359 ("HID: i2c-hid: goodix: Tie the reset line to true state of the regulator").

Included in here are: - Thunderbolt driver updates: - fixes for devices without displayport adapters - lane bonding support and improvements - other minor changes based on device testing - dwc3 gadget driver changes. It seems this driver will never be finished given that the IP core is showing up in zillions of new devices and each implementation decides to do something different with it... - uvc gadget driver updates as more devices start to use and rely on this hardware as well - usb_maxpacket() api changes to remove an unneeded and unused parameter. - usb-serial driver device id updates and small cleanups - typec cleanups and fixes based on device testing - device tree updates for usb properties - lots of other small fixes and driver updates.

2022-05-27HID: amd_sfh: Don't show client init failed as error when discovery failsMario Limonciello
When sensor discovery fails, this means that the system doesn't have any sensors connected and a user should only be notified at most one time. A message is already displayed at WARN level of "failed to discover, sensors not enabled". It's pointless to show that the client init failed at ERR level for the same condition. Check the return code and don't display this message in those conditions.

2022-05-27HID: wacom: Don't register pad_input for touch switchPing Cheng
Touch switch state is received through WACOM_PAD_FIELD. However, it is reported by touch_input. Don't register pad_input if no other pad events require the interface.

2022-05-27HID: wacom: Only report rotation for art penPing Cheng
The generic routine, wacom_wac_pen_event, turns rotation value 90 degree anti-clockwise before posting the events. This non-zero event trggers a non-zero ABS_Z event for non art pen tools. However, HID_DG_TWIST is only supported by art pen.
