platform/surface: Reinstate platform dependency

2022-01-24T09:41:45+00:00

Microsoft Surface platform-specific devices are only present on
Microsoft Surface platforms, which are currently limited to arm64 and
x86.  Hence add a dependency on ARM64 || X86, to prevent asking the user
about drivers for these devices when configuring a kernel for an
architecture that does not support Microsoft Surface platforms.

platform: surface: Propagate ACPI Dependency

2021-12-07T11:21:01+00:00

Since the Surface XBL Driver does not depend on ACPI, the
platform/surface directory as a whole no longer depends on ACPI. With
respect to this, the ACPI dependency is moved into each config that depends
on ACPI individually.

platform/surface: aggregator_registry: Rename device registration function

2021-11-16T09:56:54+00:00

Rename the device registration function to better align names with the
newly introduced device removal function.

platform/surface: aggregator_registry: Use generic client removal function

2021-11-16T09:56:54+00:00

Use generic client removal function introduced in the previous commit
instead of defining our own one.

platform/surface: aggregator: Make client device removal more generic

2021-11-16T09:56:54+00:00

Currently, there are similar functions defined in the Aggregator
Registry and the controller core.

Make client device removal more generic and export it. We can then use
this function later on to remove client devices from device hubs as well
as the controller and avoid re-defining similar things.

platform/surface: aggregator_registry: Add initial support for Surface Pro 8

2021-10-28T09:21:17+00:00

Add preliminary support for the Surface Pro 8 to the Surface Aggregator
registry. This includes battery/charger status and platform profile
support.

In contrast to earlier Surface Pro generations, the keyboard cover is
now also connected via the Surface Aggregator Module (whereas it was
previously connected via USB or HID-over-I2C). To properly support the
HID devices of that cover, however, more changes regarding hot-removal
of Surface Aggregator client devices as well as a new device hub driver
are required. We will address those things in a follow-up series, so do
not add any HID device IDs just yet.

platform/surface: aggregator_registry: Add support for Surface Laptop Studio

2021-10-21T18:36:22+00:00

Add support for the Surface Laptop Studio.

In contrast to previous Surface Laptop models, this one has its HID
devices attached to target ID 1 (instead of 2). It also has a couple
more of them, including a new notifier for when the pen is stashed /
taken out of its place, a "Sys Control" device, and two other
unidentified HID devices with unknown usages.

Battery and performance profile interfaces remain the same.

The new Surface Laptop Studio uses GPEs for lid events as well. Add an
entry for that so that the lid can be used to wake the device.

surface: surface3_power: Drop redundant acpi_bus_get_device() call

2021-10-19T14:55:53+00:00

If the ACPI companion of a given device is not present, the result
of the ACPI_HANDLE() evaluation for it will be NULL, so calling
acpi_bus_get_device() on ACPI_HANDLE() result in order to validate
it is redundant.

Drop the redundant acpi_bus_get_device() call from mshw0011_notify()
along with a local variable related to it.

No intentional functional impact.

surface: surface3-wmi: Use ACPI_COMPANION() directly

2021-10-19T14:55:43+00:00

The ACPI_HANDLE() macro is a wrapper arond the ACPI_COMPANION()
macro and the ACPI handle produced by the former comes from the
ACPI device object produced by the latter, so it is way more
straightforward to evaluate the latter directly instead of passing
the handle produced by the former to acpi_bus_get_device().

Modify s3_wmi_check_platform_device() accordingly (no intentional
functional impact).
