The Surface 3 buttons are now handled by the generic soc_button_array driver. As part of adding support to soc_button_array the ACPI code now instantiates a platform_device rather then an i2c_client so there no longer is an i2c_client for this driver to bind to.

Surface ACPI Notify (SAN) driver for Microsoft Surface devices.
|
|
|
|
This driver provides support for the ACPI interface (called SAN) of
|
|
the Surface System Aggregator Module (SSAM) EC. This interface is used
|
|
on 5th- and 6th-generation Microsoft Surface devices (including
|
|
Surface Pro 5 and 6, Surface Book 2, Surface Laptops 1 and 2, and in
|
|
reduced functionality on the Surface Laptop 3) to execute SSAM
|
|
requests directly from ACPI code, as well as receive SSAM events and
|
|
turn them into ACPI notifications. It essentially acts as a
|
|
translation layer between the SSAM controller and ACPI.
|
|
|
|
Specifically, this driver may be needed for battery status reporting,
|
|
thermal sensor access, and real-time clock information, depending on
|
|
the Surface device in question.

This option provides a module (called surface_aggregator_cdev), that,
|
|
when loaded, will add a client device (and its respective driver) to
|
|
the SSAM controller. Said client device manages a misc-device
|
|
interface (/dev/surface/aggregator), which can be used by user-space
|
|
tools to directly communicate with the SSAM EC by sending requests and
|
|
receiving the corresponding responses.
|
|

The provided interface is intended for debugging and development only,
|
|
and should not be used otherwise.

|

|

Provides a module and driver which act as a device-registry for SSAM
|
|
client devices that cannot be detected automatically, e.g. via ACPI.
|
|
Such devices are instead provided via this registry and attached via
|
|
device hubs, also provided in this module.
|
|
|
|
Devices provided via this registry are:
|
|
- Platform profile (performance-/cooling-mode) device (5th- and later
|
|
generations).
|
|
- Battery/AC devices (7th-generation).
|
|
- HID input devices (7th-generation).
|
|
|
|
Select M (recommended) or Y here if you want support for the above

|
mentioned devices on the corresponding Surface models. Without this
|
|
module, the respective devices will not be instantiated and thus any
|
|
functionality provided by them will be missing, even when drivers for
|
|
these devices are present. In other words, this module only provides
|
|
the respective client devices. Drivers for these devices still need to
|
|
be selected via the other options.

Driver for the Surface Book clipboard detachment system (DTX).
|
|
|
|
On the Surface Book series devices, the display part containing the
|
|
CPU (called the clipboard) can be detached from the base (containing a
|
|
battery, the keyboard, and, optionally, a discrete GPU) by (if
|
|
necessary) unlocking and opening the latch connecting both parts.
|
|
|
|
This driver provides a user-space interface that can influence the
|
|
behavior of this process, which includes the option to abort it in
|
|
case the base is still in use or speed it up in case it is not.
|
|
|
|
Note that this module can be built without support for the Surface
|
|
Aggregator Bus (i.e. CONFIG_SURFACE_AGGREGATOR_BUS=n). In that case,
|
|
some devices, specifically the Surface Book 3, will not be supported.

Driver for out-of-band hot-plug event signaling on Microsoft Surface
|
|
devices with hot-pluggable PCIe cards.
|
|
|
|
This driver is used on Surface Book (2 and 3) devices with a
|
|
hot-pluggable discrete GPU (dGPU). When not in use, the dGPU on those
|
|
devices can enter D3cold, which prevents in-band (standard) PCIe
|
|
hot-plug signaling. Thus, without this driver, detaching the base
|
|
containing the dGPU will not correctly update the state of the
|
|
corresponding PCIe device if it is in D3cold. This driver adds support
|
|
for out-of-band hot-plug notifications, ensuring that the device state
|
|
is properly updated even when the device in question is in D3cold.
|
|
|
|
Select M or Y here, if you want to (fully) support hot-plugging of
|
|
dGPU devices on the Surface Book 2 and/or 3 during D3cold.

Provides support for the ACPI platform profile on 5th- and later

More specifically, this driver provides ACPI platform profile support
|
|
on Microsoft Surface devices with a Surface System Aggregator Module
|
|
(SSAM) connected via the Surface Serial Hub (SSH / SAM-over-SSH). In
|
|
other words, this driver provides platform profile support on the
|
|
Surface Pro 5, Surface Book 2, Surface Laptop, Surface Laptop Go and
|
|
later. On those devices, the platform profile can significantly
|
|
influence cooling behavior, e.g. setting it to 'quiet' (default) or
|
|
'low-power' can significantly limit performance of the discrete GPU on
|
|
Surface Books, while in turn leading to lower power consumption and/or
|
|
less fan noise.

support on the above mentioned devices.
