From c1b8274dee39c791322ef35b56d667257e69bdd1 Mon Sep 17 00:00:00 2001 From: Maximilian Luz Date: Sun, 10 Oct 2021 01:27:17 +0200 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.
