HID: Add Mapping for System Microphone Mute

2023-03-11T15:43:56+00:00

[ Upstream commit 2d60f9f4f26785a00273cb81fe60eff129ebd449 ]

HUTRR110 added a new usage code for a key that is supposed to
mute/unmute microphone system-wide.

Map the new usage code(0x01 0xa9) to keycode KEY_MICMUTE.
Additionally hid-debug is adjusted to recognize this keycode as well.

HID: add mapping for KEY_DICTATE

2022-03-08T18:07:50+00:00

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

2021-09-22T10:26:22+00:00

[ Upstream commit f4abaa9eebde334045ed6ac4e564d050f1df3013 ]

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.

HID: Add Logitech Dinovo Edge battery quirk

2020-12-02T07:49:48+00:00

[ Upstream commit 7940fb035abd88040d56be209962feffa33b03d0 ]

The battery status is also being reported by the logitech-hidpp driver,
so ignore the standard HID battery status to avoid reporting the same
info twice.

Note the logitech-hidpp battery driver provides more info, such as properly
differentiating between charging and discharging. Also the standard HID
battery info seems to be wrong, reporting a capacity of just 26% after
fully charging the device.

[ Upstream commit 505f394fa239cecb76d916aa858f87ed7ea7fde4 ]

With commit 4f3882177240 hid-input started clearing of "ignored" usages
to avoid using garbage that might have been left in them. However
"battery strength" usages should not be ignored, as we do want to
use them.

HID: core: Sanitize event code and type when mapping input

2020-09-05T09:22:49+00:00

commit 35556bed836f8dc07ac55f69c8d17dce3e7f0e25 upstream.

When calling into hid_map_usage(), the passed event code is
blindly stored as is, even if it doesn't fit in the associated bitmap.

This event code can come from a variety of sources, including devices
masquerading as input devices, only a bit more "programmable".

Instead of taking the event code at face value, check that it actually
fits the corresponding bitmap, and if it doesn't:
- spit out a warning so that we know which device is acting up
- NULLify the bitmap pointer so that we catch unexpected uses

Code paths that can make use of untrusted inputs can now check
that the mapping was indeed correct and bail out if not.
