From 025a2fbd8ddc5fe6479bb5d2b0252ad9e789805f Mon Sep 17 00:00:00 2001 From: Maximilian Luz Date: Thu, 28 Oct 2021 03:28:45 +0200 Subject: [PATCH] platform/surface: aggregator_registry: Add initial support for Surface Pro 8 Add preliminary support for the Surface Pro 8 to the Surface Aggregator registry. This includes battery/charger status and platform profile support. In contrast to earlier Surface Pro generations, the keyboard cover is now also connected via the Surface Aggregator Module (whereas it was previously connected via USB or HID-over-I2C). To properly support the HID devices of that cover, however, more changes regarding hot-removal of Surface Aggregator client devices as well as a new device hub driver are required. We will address those things in a follow-up series, so do not add any HID device IDs just yet.
