[ Upstream commit ed235163c3f02329d5e37ed4485bbc39ed2568d4 ]

Add SAM client device nodes for the Surface Laptop Go 3. It seems to use
the same SAM client devices as the Surface Laptop Go 1 and 2, so re-use
their node group.

<title>platform/surface: aggregator: Fix warning when controller is destroyed in probe</title>

[ Upstream commit bc923d594db21bee0ead128eb4bb78f7e77467a4 ]

There is a small window in ssam_serial_hub_probe() where the controller
is initialized but has not been started yet. Specifically, between
ssam_controller_init() and ssam_controller_start(). Any failure in this
window, for example caused by a failure of serdev_device_open(),
currently results in an incorrect warning being emitted.

In particular, any failure in this window results in the controller
being destroyed via ssam_controller_destroy(). This function checks the
state of the controller and, in an attempt to validate that the
controller has been cleanly shut down before we try and deallocate any
resources, emits a warning if that state is not SSAM_CONTROLLER_STOPPED.

However, since we have only just initialized the controller and have not
yet started it, its state is SSAM_CONTROLLER_INITIALIZED. Note that this
is the only point at which the controller has this state, as it will
change after we start the controller with ssam_controller_start() and
never revert back. Further, at this point no communication has taken
place and the sender and receiver threads have not been started yet (and
we may not even have an open serdev device either).

Therefore, it is perfectly safe to call ssam_controller_destroy() with a
state of SSAM_CONTROLLER_INITIALIZED. This, however, means that the
warning currently being emitted is incorrect. Fix it by extending the
check.

<title>platform/surface: aggregator: fix recv_buf() return value</title>

commit c8820c92caf0770bec976b01fa9e82bb993c5865 upstream.

Serdev recv_buf() callback is supposed to return the amount of bytes
consumed, therefore an int in between 0 and count.

Do not return negative number in case of issue, when
ssam_controller_receive_buf() returns ESHUTDOWN just returns 0, e.g. no
bytes consumed, this keep the exact same behavior as it was before.

This fixes a potential WARN in serdev-ttyport.c:ttyport_receive_buf().

If platform_profile_register() fails, the driver does not propagate
the error, but instead probes successfully. This means when the driver
unbinds, the a warning might be issued by platform_profile_remove().

Fix this by propagating the error back to the caller of
surface_platform_profile_probe().

Compile-tested only.

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
commit 03c835f498b5 ("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.

<title>platform/surface: Disable for RISC-V</title>

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.

<title>platform/surface: aggregator_tabletsw: Add support for book mode in POS subsystem</title>

Devices with a type-cover have an additional "book" mode, deactivating
type-cover input and turning off its backlight. This is currently
unsupported, leading to the warning

  surface_aggregator_tablet_mode_switch 01:26:01:00:01: unknown device posture for type-cover: 6

Therefore, add support for this state and map it to enable tablet-mode.

Fixes: 37ff64cd81ff ("platform/surface: aggregator_tabletsw: Add support for Type-Cover posture source")
