The Lenovo Yoga Tablet 2 series comes in 4 versions: 830F, 830L, 1050F and 1050L. The F postfix indicates a wifi only version and the L postfix indicates a LTE version. The 830 models are 8" and the 1050 models are 10". Despite there being 8" and 10" versions all models use the same mainboard, with an identical BIOS and thus identical DMI strings, so support for all 4 models is added through a single DMI table entry. As all devices dealt with in the x86-android-tablets modules, these are x86 ACPI tablets which ships with Android x86 as factory OS. The mainboard's DSDT contain a bunch of I2C devices which are not actually there, causing various resource conflicts. Enumeration of these is skipped through the acpi_quirk_skip_i2c_client_enumeration(). Add support for manually instantiating the I2C devices which are actually present on this tablet by adding the necessary device info to the x86-android-tablets module. This has been tested on a 830F and a 1050L tablet.

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 Restructured Text 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.
