The RK3328 reference design uses an external line driver IC as a buffer on the analog codec output, enabled by the GPIO_MUTE pin, and such a configuration is currently assumed in the codec driver's direct poking of GRF_SOC_CON10 to control the GPIO_MUTE output value. However, some boards wire up analog audio yet use that pin for some other purpose, so that assumption doesn't always hold. Update this functionality to rely on an explicit GPIO descriptor, such that it can be managed at the board level.

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.
