In the reference HID sensor hub firmware all Named array enums were
0-based. There is no description of the default base of enums in HID
sensor hub specification as logical minimum should have set this base
value.
Every sensor hub implemented enum as 1-based, without explicitly setting
logical minimum to 1, because of the implementation by one of the major
OS vendor. In Linux we used logical minimum to decide the enum base.
Some sensor hub FWs already changed logical minimum from 0 to 1. We hoped
that every other vendor will follow. But that didn't happen and we had to
fix the report header for every sensor hub to change logical minimum to 1
by using .report_fixup() callback. So for every new sensor hub we had to
modify source code by adding this quirk based on the vendor and device id.
This is becoming a maintenance burden.
This patch hardcodes the logical minimum of power and report state
attributes to 1. In this way we can remove the existing quirks and also
we don't have to add more quirks.

The WACOM_HID_WD_TOUCHRINGSTATUS usage is a single bit which tells us
whether the touchring is currently in use or not. Because we need to
reset the axis value to 0 when the finger is removed, we call
'wacom_map_usage' to ensure that the required type/code values are
associated with the usage. The 'wacom_map_usage' also sets up the axis
range and resolution, however, which is not desired in this particular
case.
Although xf86-input-wacom doesn't do really do anything with the ring's
range or resolution, the libinput driver (for Wayland environments)
uses these values to provide proper angle indications to userspace.

The 'wacom_update_name' function is responsible for producing names for
the input device nodes based on the hardware device name. Commit f2209d4
added the ability to strip off prefixes like "Wacom Co.,Ltd." where the
prefix was immediately (and redundantly) followed by "Wacom". The
2nd-generation Intuos Pro 2 has such a prefix, but with a small error
(the period and comma are swapped) that prevents the existing code from
matching it. We're loath to extend the number of cases out endlessly and
so instead try to be smarter about name generation.
We observe that the cause of the redundant prefixes is HID combining the
manufacturer and product strings of USB devices together. By using the
original product name (with "Wacom" prefixed, if it does not already
exist in the string) we can bypass the gyrations to find and remove
redundant prefixes. Other devices either don't have a manufacturer string
that needs to be removed (Bluetooth, uhid) or should have their name
generated from scratch (I2C).

Although HID itself is transport-agnostic, occasionally a driver may
want to interact with the low-level transport that a device is connected
through. To do this, we need to know what kind of bus is in use. The
first guess may be to look at the 'bus' field of the 'struct hid_device',
but this field may be emulated in some cases (e.g. uhid).
More ideally, we can check which ll_driver a device is using. This
function introduces a 'hid_is_using_ll_driver' function and makes the
'struct hid_ll_driver' of the four most common transports accessible
through hid.h.

Instead of unconditionally expiring the timer and calling a long
mt_release_contacts(), we can check if some slots are used when the
timer expires.
We can also remove the timer if we happen to receive all the releases.
The logic behind the MT_IO_FLAGS_PENDING_SLOTS could be implemented by
counting how many slots are active, but using bits feels slightly more
efficient.

Instead of blindly trusting the hardware to send us release, we should
consider some events can get lost and release them when we judge time has
come.
The Windows 8 spec allows to be confident in the fact that the device
will continuously report events when a finger touches the surface.
This has been tested on the HID recording database I have, and all of
those devices behave properly.
Also, Arek tested it on his Lenovo Yoga 910, which exports such bug in
some situations, when the movements are rather slow.
We use an atomic bit here to guard against concurrent accesses to the mt
slots because both mt_process_mt_event() and mt_expired_timeout() are
called in interrupt context.

There are many situations where generic HID driver provides some basic level
of support for certain device, but later this support (usually by implementing
vendor-specific extensions of HID protocol) is extended and the support moved
over to a separate (usually per-vendor) specific driver.
This might bring a rather unpleasant suprise for users, as all of a sudden
there is a new config option they have to enable in order to get any support
for their device whatsoever, although previous kernel versions provided basic
support through the generic driver. Which is rightfully seen as a regression.
Fix this by including the entry for a particular device in
hid_have_special_driver[] iff the specific config option has been specified,
and let generic driver handle the device otherwise.
Also make the behavior of hid_scan_report() (where the same decision is being
taken on a per-report level) consistent.
While at it, reshuffle the hid_have_special_driver[] a bit to restore the
alphabetical ordering (first order by config option, and within those
sections order by VID).
This is considered a short-term solution, before generic way of giving
precedence to special drivers and falling back to generic driver is
figured out.
While at it, fixup a missing entry for GFRM driver; thanks to Hans de Geode for
spotting this (and for discovering a few issues in the conversion).

I was trying to understand this code while working on a warning
fix and the locking made no sense: spin_lock_irqsave() is pointless
when run inside of an interrupt handler or nested inside of another
spin_lock_irq() or spin_lock_irqsave().
Here it turned out that the comment above the function is wrong,
as both recv_ishtp_cl_msg_dma() and recv_ishtp_cl_msg() can in fact
be called from a work queue rather than an ISR, so we do have to
use the irqsave() version once.
This fixes the comments accordingly, removes the misleading 'dev_flags'
variable and modifies the inner spinlock to not use 'irqsave'.
No functional change is intended, this is just for readability and
it slightly simplifies the object code.

saw it in configurations that had neither SMP nor LOCKDEP enabled.
As we can see, we only enter the case if 'complete_rb' is non-NULL,
and then 'cl' is known to point to complete_rb->cl. Adding another
initialization to the same pointer is harmless here and makes it
clear to the compiler that the behavior is well-defined.

Generic battery handling code is spread between the pen and pad codepaths
since battery usages may appear in reports for either. This makes it
difficult to concisely see the logic involved. Since battery data is
not treated like other data (i.e., we report it through the power_supply
subsystem rather than through the input subsystem), it makes reasonable
sense to split the functionality out into its own functions.
This commit has the generic battery handling duplicate the same pattern
that is used by the pen, pad, and touch interfaces. A "mapping" function
is provided to set up the battery, an "event" function is provided to
update the battery data, and a "report" function is provided to notify
the power_supply subsystem after all the data has been read. We look at
the usage itself rather than its collection to determine if one of the
battery functions should handle it. Additionally, we unconditionally
call the "report" function since there is no particularly good way to
know if a report contained a battery usage; 'wacom_notify_battery()'
will filter out any duplicate updates, however.

At the moment, our driver relies on 'wacom_battery_get_property()' to
determine the most likely battery state (e.g charging, discharging, or
full) based on the information available. It is not always possible
for the function to properly determine this, however. For instance,
whenever an AES pen leaves proximity the battery state becomes
indeterminite. This commit adds the ability to provide it with explict
state information if desired. Whenever explicit state is not required
(the majority of circumstances), WACOM_POWER_SUPPLY_STATUS_AUTO can
be used in its place.

The power_supply subsystem expects us to provide it with capacity values
measured in percent. In particular, AES devices (HID_DG_BATTERYSTRENGTH)
use the range 0-255, which needs to be rescaled. The MobileStudio Pro

The driver emits multi-touch events for Magic Trackpad as well as Magic
Mouse, but it does not set keybits that are related to multi-touch event
for Magic Mouse; so set these keybits.
The keybits that are not set cause trouble because user programs often
probe these keybits for self-configuration and thus they cannot operate
properly if the keybits are not set.
One of such troubles is that libevdev will not be able to emit correct
touch count, causing gestures library failed to do fling stop.

The following Smatch complaint was generated in response to commit
2a6cdbd ("HID: wacom: Introduce new 'touch_input' device"):
drivers/hid/wacom_wac.c:1586 wacom_tpc_irq()
error: we previously assumed 'wacom->touch_input' could be null (see line 1577)
The 'touch_input' and 'pen_input' variables point to the 'struct input_dev'
used for relaying touch and pen events to userspace, respectively. If a
device does not have a touch interface or pen interface, the associated
input variable is NULL. The 'wacom_tpc_irq()' function is responsible for
forwarding input reports to a more-specific IRQ handler function. An
unknown report could theoretically be mistaken as e.g. a touch report
on a device which does not have a touch interface. This can be prevented
by only calling the pen/touch functions are called when the pen/touch
pointers are valid.

It apears that devices designed around Wacom's G11 chipset (e.g. Lenovo
ThinkPad Yoga 260, Lenovo ThinkPad X1 Yoga, Dell XPS 12 9250, Dell Venue
8 Pro 5855, etc.) suffer from a common issue in their HID descriptors.
The logical maximum is not updated for the "Contact Identifier" usage,
leaving it as just "1" despite these devices being capable of tracking
far more touches.
Commit 60a2218698 began ignoring usages with out-of-range values,
causing problems for devices based on this chipset. Touches after
the first will have an out-of-range Contact Identifier, and ignoring
that usage will cause the kernel to incorrectly slot each finger's
events (along with all the knock-on userspace effects that entails).
This commit checks for these buggy descriptors and updates the maximum
where required. Prior chipsets have used "255" as the maximum (and the
G11, at least, doesn't seem to actually use IDs outside the range of
1..CONTACTMAX) so continue using this value.

Because HID_DG_TOOLSERIALNUMBER doesn't first cast the value recieved from HID
to an unsigned type, sign-extension rules can cause the value of
wacom_wac->serial[0] to inadvertently wind up with all 32 of its highest bits
set if the highest bit of "value" was set.
This can cause problems for Tablet PC devices which use AES sensors and the
xf86-input-wacom userspace driver. It is not uncommon for AES sensors to send a
serial number of '0' while the pen is entering or leaving proximity. The
xf86-input-wacom driver ignores events with a serial number of '0' since it
cannot match them up to an in-use tool. To ensure the xf86-input-wacom driver
does not ignore the final out-of-proximity event, the kernel does not send
MSC_SERIAL events when the value of wacom_wac->serial[0] is '0'. If the highest
bit of HID_DG_TOOLSERIALNUMBER is set by an in-prox pen which later leaves
proximity and sends a '0' for HID_DG_TOOLSERIALNUMBER, then only the lowest 32
bits of wacom_wac->serial[0] are actually cleared, causing the kernel to send
an MSC_SERIAL event. Since the 'input_event' function takes an 'int' as
argument, only those lowest (now-cleared) 32 bits of wacom_wac->serial[0] are
sent to userspace, causing xf86-input-wacom to ignore the event. If the event
was the final out-of-prox event, then xf86-input-wacom may remain in a state
where it believes the pen is in proximity and refuses to allow other devices
under its control (e.g. the touchscreen) to move the cursor.
It should be noted that EMR devices and devices which use both the
HID_DG_TOOLSERIALNUMBER and WACOM_HID_WD_SERIALHI usages (in that order) would
be immune to this issue. It appears only AES devices are affected.

- Configuration command (to get keyboard status/information)
- Backlight level control (to change the level of the keyboard light)

The fix in 1989dada7c ("HID: input: ignore System Control

will utilize this functionality. Considering the driver structure
and all error handling it felt best to reuse sony_schedule_work
and sony_cancel_work. The idea was inspired by the wacom driver
which does something similar.

This patch adds a new quirk, which allows us to differentiate
between the DualShock 4 USB and the dongle. So far they have
been treated the same, but handling of calibration data differs
as the dongle behaves like Bluetooth, for other requests it
behaves like USB.
In addition this patches changes usb/dongle/bt handling in
sony_raw_event, which makes the code cleaner to read. In addition
another patch in this series will add more dongle logic, so this
change paves the road for that.

The DS4 in BT mode sends initial input reports through report 1, which
is described in the HID report descriptors. When activated after sending
a certain feature report, the device uses report 17.
Currently the hid-sony driver fixes up the BT HID report descriptors,
so the HID layer can manage input reports for report 17.
We think it is best to eliminate this fixup and do the handling ourselves,
which is what this patch does. The main motivation is that there are
various users of DS4 through hidraw, including various cross-platform
applications/games, which have their own HID parsing across Linux/Win/OSX.
Due to the fixup the descriptors differ, which is causing pain for many
developers including major game publishers (who reached out privately).
Without the fixup, the Windows titles also have a fighting chance for
working on Wine, which provides HID support now. Overall it felt
best because of these reasons to remove the fixup.

The DS4 motion sensors require calibration for accurate operation.
This patch adds calibration for both the accelerometer and the

The DS4 motion sensors are currently mapped by the hid-core driver
to non-existing axes in between ABS_MISC and ABS_MT_SLOT, because
the device already exhausted ABS_X-ABS_RZ. For a part the mapping
by hid-core is accomplished by a fixup in hid-sony as the motion
axes actually use vendor specific usage pages.
This patch makes the DS4 use a separate input device for the motion
sensors and reports acceleration data through ABS_X-ABS_Z and
gyroscope data through ABS_RX-ABS_RZ. In addition it extends the
event spec to allow gyroscope data through ABS_RX-ABS_RZ when
INPUT_PROP_ACCELEROMETER is set. This change was suggested by
Peter Hutterer during a discussion on linux-input.

It looks like a bunch of devices do not like to be polled
for their reports at init time. When you look into the details,
it seems that for those that are requiring the quirk
HID_QUIRK_NO_INIT_REPORTS, the driver fails to retrieve part
of the features/inputs while others (more generic) work.
IMO, it should be acceptable to remove the need for the quirk
in the general case. On the small amount of cases where
we actually need to read the current values, the driver
in charge (hid-mt or wacom) already retrieves the features
manually.
There are 2 cases where we might need to retrieve the reports at
init:
1. hiddev devices with specific use-space tool
2. a device that would require the driver to fetch a specific
feature/input at plug
For case 2, I have seen this a few time on hid-multitouch. It
is solved in hid-multitouch directly by fetching the feature.
I hope it won't be too common and this can be solved on a per-case
basis (crossing fingers).
For case 1, we moved the implementation of HID_QUIRK_NO_INIT_REPORTS
in hiddev. When somebody starts calling ioctls that needs an initial
update, the hiddev device will fetch the initial state of the reports
to mimic the current behavior. This adds a small amount of time during
the first HIDIOCGUSAGE(S), but it should be acceptable in
most cases. To keep the currently known broken devices, we have to
keep around HID_QUIRK_NO_INIT_REPORTS, but the scope will only be
for hiddev.
Note that I don't think hidraw would be affected and I checked that
the FF drivers that need to interact with the report fields are all
using output reports, which are not initialized by
usbhid_init_reports().
NO_INIT_INPUT_REPORTS is then replaced by HID_QUIRK_NO_INIT_REPORTS:
there is no point keeping it for just one device.

This patch fixes an issue in drivers/hid/hid-input.c where values
outside of the logical range are not clamped when "null state" bit of
the input control is not set.
This was discussed on the lists [1] and this change stems from the fact
due to the ambiguity of the HID specification it might be appropriate to
follow Microsoft's own interpretation of the specification. As noted in
Microsoft's documentation [2] in the section titled "Required HID usages
for digitizers" it is noted that values reported outside the logical
range "will be considered as invalid data and the value will be changed
to the nearest boundary value (logical min/max)."
This patch fixes an issue where the (1292:4745) Innomedia INNEX
GENESIS/ATARI reports out of range values for its X and Y axis of the
DPad which, due to the null state bit being unset, are forwarded to
userspace as is. Now these values will get clamped to the logical range
before being forwarded to userspace. This device was also used to test
this patch.
This patch expands on commit 3f3752705d ("HID: reject input outside
logical range only if null state is set").

Quoting from Jonathan Clarke in previous thread(2017/01/24):
"This division by 2 was added along with the touch width/height fields 6 years
ago so that those fields 'match the visual scale of the touch' for a specific
device (3M PCT)" "The scaling is also discarding information about touch size
(1 bit for each of width/height) which is useful for any application that wants
to know about it."
Jonathan mentioned just what I thought in a new project recently. It dosen't
make sense to discard 1 bit width/height in general case according to the spec
in multi-touch-protocol.txt so I would like to make a slight change here.
A quirk MT_QUIRK_TOUCH_SIZE_SCALING was added to service devices like 3M PCT
with a special visual scale and the division by 2 only take effect with devices
like that.

The autodetection is simply worked around by manually adding the device to
hid_have_special_driver[].
The processing of the events requires either a report fixup, or some specific
case handling. Given that the report fixup would require to basically rewrite
all the report descriptor, I went for the programatic way of fixing that after
the report descriptors are loaded.
