In linux kernel since version 6.6.86 (release Date: 2025-04-07)  
Say Y here to enable the EC driver for the Huawei Matebook E Go
which is a sc8280xp-based 2-in-1 tablet. The driver handles battery
(information, charge control) and USB Type-C DP HPD events as well
as some misc functions like the lid sensor and temperature sensors,
etc.

This driver provides battery and AC status support for the mentioned
laptop where this information is not properly exposed via the
standard ACPI devices.

Say M or Y here to include this support.
