Add nodes for i2s, digital and analog parts of audiocodec on A64. The routing paths listed are entries connecting the digital and analog side of the audio codec together. Due to how device tree works, these must be copied over to each board device tree, in addition to any board level routes. The oversampling rate is set to 128, so that when playing back 192 kHz audio samples, the MCLK runs at the same rate as the module clock, at 24.576 MHz. The user manual suggests using different oversampling rates for different sample rates, but that's not possible without a platform-specific machine driver.

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.
