8802fcfb57 platform/surface: surface3_power: Switch back to use struct i2c_driver's .probe()
After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
commit 03c835f498 ("i2c: Switch .probe() to not take an id parameter")
convert back to (the new) .probe() to be able to eventually drop
.probe_new() from struct i2c_driver.

platform/surface: Disable for RISC-V
With CONFIG_ACPI enabled for RISC-V, this driver gets enabled
in allmodconfig build. However, RISC-V doesn't support sub-word
atomics which is used by this driver and hence allmodconfig
build will fail.

There is currently no plan to support this driver for RISC-V. So,
disable this driver for RISC-V even when ACPI is enabled.

539e0a7f91 platform/surface: aggregator: Allow completion work-items to be executed in parallel
Currently, event completion work-items are restricted to be run strictly
in non-parallel fashion by the respective workqueue. However, this has
lead to some problems:

In some instances, the event notifier function called inside this
completion workqueue takes a non-negligible amount of time to execute.
One such example is the battery event handling code (surface_battery.c),
which can result in a full battery information refresh, involving
further synchronous communication with the EC inside the event handler.
This is made worse if the communication fails spuriously, generally
incurring a multi-second timeout.

Since the event completions are run strictly non-parallel, this blocks
other events from being propagated to the respective subsystems. This
becomes especially noticeable for keyboard and touchpad input, which
also funnel their events through this system. Here, users have reported
occasional multi-second "freezes".

Note, however, that the event handling system was never intended to run
purely sequentially. Instead, we have one work struct per EC/SAM
subsystem, processing the event queue for that subsystem. These work
structs were intended to run in parallel, allowing sequential processing
of work items for each subsystem but parallel processing of work items
across subsystems.

The only restriction to this is the way the workqueue is created.
Therefore, replace create_workqueue() with alloc_workqueue() and do not
restrict the maximum number of parallel work items to be executed on
that queue, resolving any cross-subsystem blockage.

b58a444d7f platform/surface: aggregator_tabletsw: Properly handle different posture source IDs
The device posture subsystem (POS) can provide different posture
sources. Different sources can provide different posture states and
sources can be identified by their ID.

For example, screen posture of the Surface Laptop Studio (SLS), which is
currently the only supported source, uses a source ID of 0x03. The
Surface Pro 9 uses the same subsystem for its Type-Cover, however,
provides different states for that under the ID 0x00.

To eventually support the Surface Pro 9 and potential future devices, we
need to properly disambiguate between source IDs. Therefore, add the
source ID to the state we carry and determine the tablet-mode state (as
well as state names) based on that.

a93e884edf Driver core changes for 6.3-rc1
Here is the large set of driver core changes for 6.3-rc1.
 
 There's a lot of changes this development cycle, most of the work falls
 into two different categories:
   - fw_devlink fixes and updates.  This has gone through numerous review
     cycles and lots of review and testing by lots of different devices.
     Hopefully all should be good now, and Saravana will be keeping a
     watch for any potential regression on odd embedded systems.
   - driver core changes to work to make struct bus_type able to be moved
     into read-only memory (i.e. const)  The recent work with Rust has
     pointed out a number of areas in the driver core where we are
     passing around and working with structures that really do not have
     to be dynamic at all, and they should be able to be read-only making
     things safer overall.  This is the contuation of that work (started
     last release with kobject changes) in moving struct bus_type to be
     constant.  We didn't quite make it for this release, but the
     remaining patches will be finished up for the release after this
     one, but the groundwork has been laid for this effort.
 
 Other than that we have in here:
   - debugfs memory leak fixes in some subsystems
   - error path cleanups and fixes for some never-able-to-be-hit
     codepaths.
   - cacheinfo rework and fixes
   - Other tiny fixes, full details are in the shortlog
 
 All of these have been in linux-next for a while with no reported
 problems.

b09ee1cd59 platform/surface: aggregator: Rename top-level request functions to avoid ambiguities
We currently have a struct ssam_request_sync and a function
ssam_request_sync(). While this is valid C, there are some downsides to
it.

One of these is that current Sphinx versions (>= 3.0) cannot
disambiguate between the two (see disucssion and pull request linked
below). It instead emits a "WARNING: Duplicate C declaration" and links
for the struct and function in the resulting documentation link to the
same entry (i.e. both to either function or struct documentation)
instead of their respective own entries.

While we could just ignore that and wait for a fix, there's also a point
to be made that the current naming can be somewhat confusing when
searching (e.g. via grep) or trying to understand the levels of
abstraction at play:

We currently have struct ssam_request_sync and associated functions
ssam_request_sync_[alloc|free|init|wait|...]() operating on this struct.
However, function ssam_request_sync() is one abstraction level above
this. Similarly, ssam_request_sync_with_buffer() is not a function
operating on struct ssam_request_sync, but rather a sibling to
ssam_request_sync(), both using the struct under the hood.

Therefore, rename the top level request functions:

  ssam_request_sync() -> ssam_request_do_sync()
  ssam_request_sync_with_buffer() -> ssam_request_do_sync_with_buffer()
  ssam_request_sync_onstack() -> ssam_request_do_sync_onstack()

13eca7d74e platform/surface: aggregator_registry: Fix target-ID of base-hub
The target ID of the base hub is currently set to KIP (keyboard/
peripherals). However, even though it manages such devices with the KIP
target ID, the base hub itself is actually accessed via the SAM target
ID. So set it accordingly.

Note that the target ID of the hub can be chosen arbitrarily and does
not directly correspond to any physical or virtual component of the EC.
This change is only a code improvement intended for consistency and
clarity, it does not fix an actual bug.

78abf1b520 platform/surface: aggregator: Enforce use of target-ID enum in device ID macros
Similar to the target category (TC), the target ID (TID) can be one
value out of a small number of choices, given in enum ssam_ssh_tid.

In the device ID macros, SSAM_SDEV() and SSAM_VDEV() we already use text
expansion to, both, remove some textual clutter for the target category
values and enforce that the value belongs to the known set. Now that we
know the names for the target IDs, use the same trick for them as well.

Also rename the SSAM_ANY_x macros to SSAM_SSH_x_ANY to better fit in.

2730fc0ab4 platform/surface: aggregator: Add target and source IDs to command trace events
Add command source and target IDs to trace events.

Tracing support for the Surface Aggregator driver was originally
implemented at a time when only two peers were known: Host and SAM. We
now know that there are at least five, with three actively being used
(Host, SAM, KIP; four with Debug if you want to count manually enabling
that interface). So it makes sense to also explicitly name the peers
involved when tracing.

c965daac37 platform/surface: aggregator: Add missing call to ssam_request_sync_free()
Although rare, ssam_request_sync_init() can fail. In that case, the
request should be freed via ssam_request_sync_free(). Currently it is
leaked instead. Fix this.

ae0fa0a312 platform/surface: aggregator: Ignore command messages not intended for us
It is possible that we (the host/kernel driver) receive command messages
that are not intended for us. Ignore those for now.

The whole story is a bit more complicated: It is possible to enable
debug output on SAM, which is sent via SSH command messages. By default
this output is sent to a debug connector, with its own target ID
(TID=0x03). It is possible to override the target of the debug output
and set it to the host/kernel driver. This, however, does not change the
original target ID of the message. Meaning, we receive messages with
TID=0x03 (debug) but expect to only receive messages with TID=0x00
(host).

The problem is that the different target ID also comes with a different
scope of request IDs. In particular, these do not follow the standard
event rules (i.e. do not fall into a set of small reserved values).
Therefore, current message handling interprets them as responses to
pending requests and tries to match them up via the request ID. However,
these debug output messages are not in fact responses, and therefore
this will at best fail to find the request and at worst pass on the
wrong data as response for a request.

Therefore ignore any command messages not intended for us (host) for
now. We can implement support for the debug messages once we have a
better understanding of them.

Note that this may also provide a bit more stability and avoid some
driver confusion in case any other targets want to talk to us in the
future, since we don't yet know what to do with those as well. A warning
for the dropped messages should suffice for now and also give us a
chance of discovering new targets if they come along without any
potential for bugs/instabilities.

45494d77f2 Merge branches 'acpi-scan', 'acpi-bus', 'acpi-tables' and 'acpi-sysfs'
Merge ACPI changes related to device enumeration, device object
managenet, operation region handling, table parsing and sysfs
interface:

 - Use ZERO_PAGE(0) instead of empty_zero_page in the ACPI device
   enumeration code (Giulio Benetti).

 - Change the return type of the ACPI driver remove callback to void and
   update its users accordingly (Dawei Li).

 - Add general support for FFH address space type and implement the low-
   level part of it for ARM64 (Sudeep Holla).

 - Fix stale comments in the ACPI tables parsing code and make it print
   more messages related to MADT (Hanjun Guo, Huacai Chen).

 - Replace invocations of generic library functions with more kernel-
   specific counterparts in the ACPI sysfs interface (Christophe JAILLET,
   Xu Panda).

* acpi-scan:
  ACPI: scan: substitute empty_zero_page with helper ZERO_PAGE(0)

* acpi-bus:
  ACPI: FFH: Silence missing prototype warnings
  ACPI: make remove callback of ACPI driver void
  ACPI: bus: Fix the _OSC capability check for FFH OpRegion
  arm64: Add architecture specific ACPI FFH Opregion callbacks
  ACPI: Implement a generic FFH Opregion handler

* acpi-tables:
  ACPI: tables: Fix the stale comments for acpi_locate_initial_tables()
  ACPI: tables: Print CORE_PIC information when MADT is parsed

* acpi-sysfs:
  ACPI: sysfs: use sysfs_emit() to instead of scnprintf()
  ACPI: sysfs: Use kstrtobool() instead of strtobool()

6c0eb5ba35 ACPI: make remove callback of ACPI driver void
For bus-based driver, device removal is implemented as:
1 device_remove()->
2   bus->remove()->
3     driver->remove()

Driver core needs no inform from callee(bus driver) about the
result of remove callback. In that case, commit fc7a6209d5
("bus: Make remove callback return void") forces bus_type::remove
be void-returned.

Now we have the situation that both 1 & 2 of calling chain are
void-returned, so it does not make much sense for 3(driver->remove)
to return non-void to its caller.

So the basic idea behind this change is making remove() callback of
any bus-based driver to be void-returned.

This change, for itself, is for device drivers based on acpi-bus.

Add device nodes to enable support for battery and charger status, the
ACPI platform profile, as well as internal and type-cover HID devices
(including sensors, touchpad, keyboard, and other miscellaneous devices)
on the Surface Pro 9.

This does not include support for a tablet-mode switch yet, as that is
now handled via the POS subsystem (unlike the Surface Pro 8, where it is
handled via the KIP subsystem) and therefore needs further changes.

While we're at it, also add the missing comment for the Surface Pro 8.

d9a477f643 platform/surface: aggregator: Do not check for repeated unsequenced packets
Currently, we check any received packet whether we have already seen it
previously, regardless of the packet type (sequenced / unsequenced). We
do this by checking the sequence number. This assumes that sequence
numbers are valid for both sequenced and unsequenced packets. However,
this assumption appears to be incorrect.

On some devices, the sequence number field of unsequenced packets (in
particular HID input events on the Surface Pro 9) is always zero. As a
result, the current retransmission check kicks in and discards all but
the first unsequenced packet, breaking (among other things) keyboard and
touchpad input.

Note that we have, so far, only seen packets being retransmitted in
sequenced communication. In particular, this happens when there is an
ACK timeout, causing the EC (or us) to re-send the packet waiting for an
ACK. Arguably, retransmission / duplication of unsequenced packets
should not be an issue as there is no logical condition (such as an ACK
timeout) to determine when a packet should be sent again.

Therefore, remove the retransmission check for unsequenced packets
entirely to resolve the issue.

a776bf77c9 platform/surface: Split memcpy() of struct ssam_event flexible array
To work around a misbehavior of the compiler's ability to see into
composite flexible array structs (as detailed in the coming memcpy()
hardening series[1]), split the memcpy() of the header and the payload
so no false positive run-time overflow warning will be generated.

c6607bcbbe platform/surface: aggregator_registry: Add HID devices for sensors and UCSI client to SP8
Add software nodes for the HID sensor collection and the UCM UCSI HID
client to the Surface Pro 8. In contrast to the type-cover devices,
these devices are directly attached to the SAM controller, without any
hub.

This enables support for HID-based sensors, including the ones used for
automatic screen rotation, on the Surface Pro 8.

ed5c2f5fd1 i2c: Make remove callback return void
The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Move helper functions for client device registration to the core module.
This simplifies addition of future DT/OF support and also allows us to

At the same time, also improve device node validation a bit by not
silently skipping devices with invalid device UID specifiers. Further,
ensure proper lifetime management for the firmware/software nodes
associated with the added devices.
