platform/surface: aggregator_registry: Add HID devices for sensors and UCSI client to SP8

2022-08-15T13:04:51+00:00

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.

platform/surface: aggregator_registry: Rename HID device nodes based on new findings

2022-08-15T13:04:41+00:00

On Windows, the HID devices with target ID 1 are grouped as "Surface Hot
Plug - SAM". Rename their device nodes in the registry to reflect that
and update the comments accordingly.

platform/surface: aggregator_registry: Rename HID device nodes based on their function

2022-08-15T13:04:37+00:00

Rename HID device nodes based on their function. In particular, these
are nodes for firmware updates via the CFU mechanism (component firmware
update), HID based sensors, and a USB-C UCSI client.

platform/surface: aggregator_registry: Add support for Surface Laptop Go 2

2022-08-15T11:20:38+00:00

The Surface Laptop Go 2 seems to have the same SAM client devices as the
Surface Laptop Go 1, so re-use its node group.

platform/surface: gpe: Add support for 13" Intel version of Surface Laptop 4

2022-07-28T18:40:40+00:00

The 13" Intel version of the Surface Laptop 4 uses the same GPE as the
Surface Laptop Studio for wakeups via the lid. Set it up accordingly.

platform/surface: tabletsw: Fix __le32 integer access

2022-07-17T14:20:35+00:00

The sources.count field is a __le32 inside a packed struct. So use the
proper functions to access it.

platform/surface: aggregator: Move subsystem hub drivers to their own module

2022-07-02T09:23:25+00:00

Split out subsystem device hub drivers into their own module. This
allows us to load the hub drivers separately from the registry, which
will help future DT/OF support.

While doing so, also remove a small bit of code duplication.

platform/surface: aggregator: Move device registry helper functions to core module

2022-07-02T09:23:14+00:00

Move helper functions for client device registration to the core module.
This simplifies addition of future DT/OF support and also allows us to
split out the device hub drivers into their own module.

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.
