The keyboard of this device has the following in its report description
for Usage (Keyboard) in Collection (Application):
# 0x15, 0x00, // Logical Minimum (0) 52
# 0x25, 0x65, // Logical Maximum (101) 54
# 0x05, 0x07, // Usage Page (Keyboard) 56
# 0x19, 0x00, // Usage Minimum (0) 58
# 0x29, 0xdd, // Usage Maximum (221) 60
# 0x81, 0x00, // Input (Data,Arr,Abs) 62
Since the Usage Min/Max range exceeds the Logical Min/Max range,
keypresses outside the Logical range are not recognized. This includes,
for example, the Japanese language keyboard variant's keys for |, _ and
\.
Fixup the report description to make the Logical range match the Usage
range, fixing the interpretation of keypresses above 101 on this device.

Based on available evidence, the USB ID 4c4a:4155 used by multiple
devices has been attributed to Jieli. The commit 1a8953f4f774
("HID: Add IGNORE quirk for SMARTLINKTECHNOLOGY") affected touchscreen
functionality. Added checks for manufacturer and serial number to
maintain microphone compatibility, enabling both devices to function

The same suspend and resume callbacks are used for both suspend-to-RAM/idle
and hibernation. These callbacks invoke pm_suspend_via_firmware() and
pm_resume_via_firmware(), respectively. In the .freeze() of hibernation,
pm_suspend_via_firmware() returns false, causing the driver to put ISH into
D0i3. However, during the .thaw(), pm_resume_via_firmware() returns true,
leading the driver to treat ISH as resuming from D3 instead of D0i3. The
asymmetric behavior between .freeze() and .thaw() during hibernation can
cause the client connection states on the firmware side and the driver side
to become inconsistent.
To address the inconsistent client connection states issue, separate
hibernate-related callbacks (freeze, thaw) in dev_pm_ops. Since ISH does
not need to save any firmware-related state when entering hibernation, it
is sufficient to call pci_save_state() in .freeze() to prevent the PCI bus
from changing the ISH power state. No actions are required in .thaw().

On ISH power-up, the bootloader enters sleep after preparing to load the
main firmware, waiting for the driver to be ready. When the driver is
ready, it sends a void message to wake up the bootloader and load the main
firmware. The main firmware then sends MNG_RESET_NOTIFY to the driver for
handshake.
This void message-based IPC handshake only works if the main firmware has
not been loaded. During hibernation resume, if the restore kernel has the
ISH driver, the driver wakes up the bootloader to load the main firmware
and perform IPC handshake. However, when switching to the image kernel,
since the main firmware is already loaded, sending a void message in the
.restore() callback does not trigger IPC handshake.
By sending MNG_RESET_NOTIFY (IPC RESET message) in ish_wakeup() instead of
a void message, we can explicitly wake up the bootloader and perform IPC
handshake, regardless of the firmware state. Additionally, since
ish_ipc_reset() already waits for recvd_hw_ready, the redundant wait for
recvd_hw_ready in ish_hw_start() is removed.
The timeout for waiting for HW ready is set to 10 seconds, matching the
original timeout value used in ish_wakeup(), to ensure reliable wakeup on
hardware that requires more time, such as the Lenovo ThinkPad X1 Titanium
Gen 1.

Both ISH firmware and driver can actively send MNG_RESET_NOTIFY to initiate
an FW reset handshake. Upon receiving this, the peer should reply with
MNG_RESET_NOTIFY_ACK. Therefore, the driver should schedule the FW reset
handshake work function when receiving either MNG_RESET_NOTIFY or
MNG_RESET_NOTIFY_ACK.
Previously, driver only scheduled the work function on MNG_RESET_NOTIFY.
This patch ensures the work function is scheduled on both messages, but
only replies with MNG_RESET_NOTIFY_ACK when receiving MNG_RESET_NOTIFY.

When ISH resumes from D3, the connection between ishtp clients and firmware
is lost. The ish_resume() function schedules resume_work asynchronously to
re-initiate the connection and then returns immediately. This can cause a
race where the upper-layer ishtp client driver's .resume() may execute
before the connection is fully restored, leaving the client in a stale
connected state. If the client sends messages during this window, the
firmware cannot respond.
To avoid this, reset the ishtp clients' state before returning from
ish_resume() if ISH is resuming from D3.

When resuming from suspend-to-RAM or hibernate, the ISH firmware is powered
on from D3, causing all previous client connections between the firmware
and driver to be lost. Although the underlying ishtp bus driver initiates a
client reconnection flow, this process is asynchronous. As a result, when
hid_ishtp_cl_resume_handler() is executed, the connection may not have been
re-established yet. Clearing the suspended flag prematurely in this
scenario can lead to a timeout when the upper-layer HID sensor driver set
feature during resume.
To prevent such timeouts, only clear the suspended flag after confirming
that the connection state is ISHTP_CL_CONNECTED.

During suspend/resume tests with S2IDLE, some ISH functional failures were
observed because of delay in executing ISH resume handler. Here
schedule_work() is used from resume handler to do actual work.
schedule_work() uses system_wq, which is a per CPU work queue. Although
the queuing is not bound to a CPU, but it prefers local CPU of the caller,
unless prohibited.
Users of this work queue are not supposed to queue long running work.
But in practice, there are scenarios where long running work items are
queued on other unbound workqueues, occupying the CPU. As a result, the
ISH resume handler may not get a chance to execute in a timely manner.
In one scenario, one of the ish_resume_handler() executions was delayed
nearly 1 second because another work item on an unbound workqueue occupied
the same CPU. This delay causes ISH functionality failures.
A similar issue was previously observed where the ISH HID driver timed out
while getting the HID descriptor during S4 resume in the recovery kernel,
likely caused by the same workqueue contention problem.
Create dedicated unbound workqueues for all ISH operations to allow work
items to execute on any available CPU, eliminating CPU-specific bottlenecks
and improving resume reliability under varying system loads. Also ISH has
three different components, a bus driver which implements ISH protocols, a
PCI interface layer and HID interface. Use one dedicated work queue for all
of them.

HID_DG_PEN devices should have a suffix of "Stylus", as pointed out by
commit c0ee1d571626 ("HID: hid-input: Add suffix also for HID_DG_PEN").
However, on multitouch devices, these suffixes may be overridden. Before
that commit, HID_DG_PEN devices would get the "Stylus" suffix, but after
that, multitouch would override them to have an "UNKNOWN" suffix. Just add
HID_DG_PEN to the list of non-overriden suffixes in multitouch.

Commit 581c4484769e ("HID: input: map digitizer battery usage") added
handling of battery events for digitizers (typically for batteries
presented in stylii). Digitizers typically report correct battery levels
only when stylus is actively touching the surface, and in other cases
they may report battery level of 0. To avoid confusing consumers of the
battery information the code was added to filer out reports with 0
battery levels.
However there exist other kinds of devices that may legitimately report
0 battery levels. Fix this by filtering out 0-level reports only for
digitizer usages, and continue reporting them for other kinds of devices
(Smart Batteries, etc).

The tablet is similar to the 22R Pro, but with a few annoying
differences. Its descriptors are bigger because of the tablet's split
coordinate system, I guess it's just that large. Thankfully, this is
easy enough to support as all we have to do is shift bytes around.
To help code re-use, I changed the signature of
uclogic_params_init_ugee_xppen_pro to accept a pen descriptor so we
didn't create yet-another initialization function.
I have been testing this locally for a month or so and it works great,
and also corroborated this with a few other testers. Since this touches
my 22R Pro code, I have tested and checked that it didn't regress that
device.

Currently, hidpp_send_message_sync() retries sending the message when the
device returns a busy error code, specifically HIDPP20_ERROR_BUSY, which
has a different meaning under RAP. This ends up being a problem because
this function is used for both FAP and RAP messages.
This issue is not noticeable on older receivers with unreachable devices
since they return HIDPP_ERROR_RESOURCE_ERROR (0x09), which is not equal to
HIDPP20_ERROR_BUSY (0x08).
However, newer receivers return HIDPP_ERROR_UNKNOWN_DEVICE (0x08) which
happens to equal to HIDPP20_ERROR_BUSY, causing unnecessary retries when
the device is not actually busy.
This is resolved by checking if the error response is FAP or RAP and
picking the respective ERROR_BUSY code.

When logitech-hidpp tries to communicate with an unreachable device paired
to a 046d:c547 lightspeed receiver, the following message is printed to the
console:
hidpp_root_get_protocol_version: received protocol error 0x08
This occurs because this receiver returns 0x08 (HIDPP_ERROR_UNKNOWN_DEVICE)
when a device is unreachable, compared to 0x09 (HIDPP_ERROR_RESOURCE_ERROR)
that the older receivers return.
This patch silences this harmless error by treating
HIDPP_ERROR_UNKNOWN_DEVICE the same as HIDPP_ERROR_RESOURCE_ERROR
in hidpp_root_get_protocol_version().
There are other checks for HIDPP_ERROR_RESOURCE_ERROR found in
battery-related functions, however this receiver does not trigger them when

New keyboard and mouse descriptors have been added to reflect these

edge detection
The original implementation used level detection for the first interrupt
after device reset to avoid potential interrupt line noise and missed
interrupts during the initialization phase. However, this approach
introduced unintended side effects when tested with certain touch panels,
including:
- Delayed hardware interrupt response
- Multiple spurious interrupt triggers
Switching back to edge detection for the first interrupt resolves these
issues while maintaining reliable interrupt handling.
Extensive testing across multiple platforms with touch panels from
various vendors confirms this change introduces no regressions.

At present VMBus driver is hinged off of CONFIG_HYPERV which entails
lot of builtin code and encompasses too much. It's not always clear
what depends on builtin hv code and what depends on VMBus. Setting
CONFIG_HYPERV as a module and fudging the Makefile to switch to builtin
adds even more confusion. VMBus is an independent module and should have
its own config option. Also, there are scenarios like baremetal dom0/root
where support is built in with CONFIG_HYPERV but without VMBus. Lastly,
there are more features coming down that use CONFIG_HYPERV and add more
dependencies on it.
So, create a fine grained HYPERV_VMBUS option and update Kconfigs for
dependency on VMBus.
