The Vexia EDU ATLA 10 tablet has an embedded controller instead of giving the os direct access to the charger + fuel-gauge ICs as is normal on tablets designed for Android. There is ACPI Battery device in the DSDT using the EC which should work except that it expects the I2C controller to be enumerated as an ACPI device and the tablet's BIOS enumerates all LPSS devices as PCI devices (and changing the LPSS BIOS settings from PCI -> ACPI does not work). Add a power_supply class driver for the Atla 10 EC to expert battery info to userspace. This is made part of the x86-android-tablets directory and Kconfig option because the i2c_client it binds to is instantiated by the x86-android-tablets kmod.

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.
