Subject: [PATCH] platform/surface: aggregator_registry: Add support for
|
|
Surface Laptop Studio
|
|
|
|
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.
