This series provides battery and AC drivers for Microsoft Surface
devices, where this information is provided via an embedded controller
(the Surface System Aggregator Module, SSAM) instead of the usual ACPI
interface.

Specifically, 7th generation Surface devices, i.e. Surface Pro 7,
Surface Book 3, Surface Laptop 3, as well as the Surface Laptop Go use
this new interface.

Note: This series depends on the

platform/surface: Add Surface Aggregator device registry

series. More specifically patch

platform/surface: Set up Surface Aggregator device registry

The full series has been merged into the for-next branch of the
platform-drivers-x86 tree [1]. The commit in question can be found at
