The base-mounted accelerometer on Chromebooks return values same as the
display when the lid angle is 180 degrees, instead of when the lid is
closed. To match userspace expectations we must further rotate the
existing accelerometer mounting matrix by 180 degrees around the X axis:
[[-1, 0, 0], [[ 1, 0, 0], [[-1, 0, 0],
[ 0, -1, 0], X [ 0, -1, 0], = [ 0, 1, 0],
[ 0, 0, -1]] [ 0, 0, -1]] [ 0, 0, 1]]
A previous commit lets us distinguish between the two cros-ec-accel
devices on these boards by their 'label' sysfs file. Add hwdb entries
that make base-mounted accelerometers use this correct matrix, and
display-mounted ones use the existing one.
Note that the cros-ec-accel drivers use 'label' only since Linux v6.0.
The old match strings are not removed to support older kernels, even
though they are only correct for the display-mounted sensor.
The IIO subsystem exposes a 'label' sysfs file to help userspace better
identify its devices [1]. Standardized labels include the sensor type
along with its location, including 'accel-base' and 'accel-display'.
Most Chrome OS boards have two accelerometers that are indistinguishable
except for this label (or a 'location' sysfs file before Linux v6.0),
and need different mounting matrix corrections based on their location.
Add a udev rule that matches hwdb entries using this label, so we can
correct both accelerometers on these devices with hwdb entries. The
existing rules and hwdb entries are not modified to keep potential
out-of-tree entries working, but new entries in this form will override
existing ones. Also add currently standardized labels to parse-hwdb.py.

The cros-ec-accel and cros-ec-accel-legacy kernel modules internally
correct for the board-specific accelerometer mounting orientations.
Their sensor outputs are in a standard reference frame consistent across
different boards, so the orientation matrix already added for a number
of devices should apply to every device using cros-ec accelerometers.
The different matrix for the 'Nocturne' board seems to be an error.
Replace the existing hwdb rules for select Chromebooks with generic
rules that apply to all Chromebooks.
They're floppy disk flux readers and writers used in digital
preservation and can be broadly considered to be "analyzers" of magnetic
fluxes.
This will have the intended side-effect of giving access to the device
to users at the console, obsoleting:

This device implements the phone mute HID usage as a toggle switch,
where 1 indicates muted, and 0 indicates unmuted. However, for a key
event 1 indicates that the key has been pressed and 0 indicates it has
been released. This mismatch causes issues, so prevent key events from
being generated for this HID usage.
It has been shown that the autosuspend delay for this device enacted
by modem manager will race with suspend and cause system suspend
failures.
This occurred in ChromiumOS on a chromebook, but there is no reason
it won't happen in regular notebooks with the same WWAN. To avoid
the failure delay autosuspend to a frequency longer than the polling
rate used by modem manager.

For micmute userspace handles both micmute and f20, as Xorg cannot
handle the high keycode that the micmute key has. As such, adding the
remapping means that the key will work on Xorg clients and not just when
using wayland.
Add keymappings for the Acer Aspire One AO532h netbook.
Unmap the brightnesskeys because they send duplicate key events with
the ACPI video bus key events and add a mapping for the bluetooth
on/off hotkey.
We've had this text since the beginning, but in fact the patterns must be
stable in order for people to create local hwdb entries. And we support that
and can't change the match patterns without being very careful. So let's just
drop the text.
The handling of whitespace in pyparsing is a bother. There's some
global state, and per-element state, and it's hard to get a handle on
things. With python3-pyparsing-2.4.7-10.fc36.noarch the grammar would
not match. After handling of tabs was fixed to not accept duplicate tabs,
the grammar passes.
It seems that the entry for usb:v8087p8087*
was generated incorrectly because we treated the interface line
(with two TABs) as a device line (with one TAB).
On the new Elite x360 2 in 1 HP laptops, the microphone mute hotkey is "Fn+F8" and
the scancode for this hotkey is 0x81, but this scancode was mapped to
fn_esc in the HP generic keymap section. To fix this problem, we add
a machine specific keymap section to add the correct keymap rule.
The Stream Deck products from Elgato are simple key pads
intended to be used as macro pads. They're popular within
the streaming community.
This commit adds all 5 Stream Deck variants available to
the AV production file.
