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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
