2021-03-30HID: Add support for Surface Aggregator Module HID transportMaximilian Luz1-0/+77
Add a HID transport driver to support integrated HID devices on newer Microsoft Surface models (specifically 7th-generation, i.e. Surface Laptop 3, Surface Book 3, and later). On those models, the internal keyboard and touchpad (as well as some other HID devices with currently unknown function) are connected via the generic HID subsystem (TC=0x15) of the Surface System Aggregator Module (SSAM). This subsystem provides a generic HID transport layer, support for which is implemented by this driver.
