HID: add mapping for KEY_ALL_APPLICATIONS

2022-03-08T18:14:18Z

commit 327b89f0acc4c20a06ed59e4d9af7f6d804dc2e2 upstream. This patch adds a new key definition for KEY_ALL_APPLICATIONS and aliases KEY_DASHBOARD to it. It also maps the 0x0c/0x2a2 usage code to KEY_ALL_APPLICATIONS.

HID: add mapping for KEY_DICTATE

2022-03-08T18:14:18Z

commit bfa26ba343c727e055223be04e08f2ebdd43c293 upstream. Numerous keyboards are adding dictate keys which allows for text messages to be dictated by a microphone. This patch adds a new key definition KEY_DICTATE and maps 0x0c/0x0d8 usage code to this new keycode. Additionally hid-debug is adjusted to recognize this new usage code as well.

HID: Ignore battery for Elan touchscreen on HP Envy X360 15t-dr100

2022-01-27T11:01:16Z

commit f3193ea1b6779023334faa72b214ece457e02656 upstream. Battery status on Elan tablet driver is reported for the HP ENVY x360 15t-dr100. There is no separate battery for the Elan controller resulting in a battery level report of 0% or 1% depending on whether a stylus has interacted with the screen. These low battery level reports causes a variety of bad behavior in desktop environments. This patch adds the appropriate quirk to indicate that the batery status is unused for this target.

HID: input: set usage type to key on keycode remap

2021-11-19T14:48:22Z

When a scancode is manually remapped that previously was not handled as key, then the old usage type was incorrectly reused. This caused issues on a "04b3:301b IBM Corp. SK-8815 Keyboard" which has marked some of its keys with an invalid HID usage. These invalid usage keys are being ignored since support for USB programmable buttons was added. The scancodes are however remapped explicitly by the systemd hwdb to the keycodes that are printed on the physical buttons. During this mapping step the existing usage is retrieved which will be found with a default type of 0 (EV_SYN) instead of EV_KEY. The events with the correct code but EV_SYN type are not forwarded to userspace. This also leads to a kernel oops when trying to print the report descriptor via debugfs. hid_resolv_event() tries to resolve a EV_SYN event with an EV_KEY code which leads to an out-of-bounds access in the EV_SYN names array.

HID: input: do not report stylus battery state as "full"

2021-07-15T18:55:30Z

The power supply states of discharging, charging, full, etc, represent state of charging, not the capacity level of the battery (for which we have a separate property). Current HID usage tables to not allow for expressing charging state of the batteries found in generic styli, so we should simply assume that the battery is discharging even if current capacity is at 100% when battery strength reporting is done via HID interface. In fact, we were doing just that before commit 581c4484769e. This change helps UIs to not mis-represent fully charged batteries in styli as being charging/topping-off.
