Subject: [PATCH 1/3] platform/surface: aggregator_registry: Add support for Surface Laptop Studio
Date: Thu, 21 Oct 2021 15:09:02 +0200 [thread overview]
Message-ID: <20211021130904.862610-2-luzmaximilian@gmail.com> (raw)
In-Reply-To: <20211021130904.862610-1-luzmaximilian@gmail.com>
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.
