Nikita Travkin 2b3efb7c51 platform: arm64: Add Acer Aspire 1 embedded controller driver ... Acer Aspire 1 is a Snapdragon 7c based laptop. It uses an embedded controller to perform a set of various functions, such as: - Battery and charger monitoring; - Keyboard layout control (i.e. fn_lock settings); - USB Type-C DP alt mode HPD notifications; - Laptop lid status. Unfortunately, while all this functionality is implemented in ACPI, it's currently not possible to use ACPI to boot Linux on such Qualcomm devices. To allow Linux to still support the features provided by EC, this driver reimplments the relevant ACPI parts. This allows us to boot the laptop with Device Tree and retain all the features.
