The Xiaomi Redmi 2 is a MSM8916 smartphone that was made by Wingtech (codename: wt88047). It's fairly similar to the other MSM8916 devices. The device tree contains initial support for the Xiaomi Redmi 2 with: - UART (untested, probably available via some test points) - eMMC/SD card - Buttons - Vibrator - WiFi/Bluetooth (WCNSS) - USB Note that the Xiaomi Redmi 2 is available in variants with different names (e.g. Redmi 2 Prime, Redmi 2 Pro, ...). As far as I know the main difference between those is the amount of RAM and supported LTE bands. This difference is automatically handled by bootloader/modem firmware so there is no need for separate device trees.

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.
