The machine driver bdw-rt5650 (for Google buddy) supports 2 or 4-channel recording while other two drivers support only 2-channel recording. HW constraints are implemented to reflect the hardware limitation on BDW platform. Changes since v1: - Change the patch title. - Remove the DUAL_CHANNEL and QUAD_CHANNEL macros which are too obvious. - Follow the naming convertion, using 'bdw_rt5650_' and 'bdw_rt5677_' to name startup functions. - Refine the comments in startup functions. - Redesign the bdw_rt5650_fe_startup() function for readability. - Add an assignment to initialize runtime->hw.channels_max variable.

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.
