Ak4458 can't support DSD512 format, but ak4497 can, so add a new enum variable (enum ak4458_type) in ak4458_drvdata to distinguish these two platforms. Ak4497 has two kinds of DSD input pin, it can be selected by the dsd-path property from DT. In hw_params(), bit clock is calculated according to different DSD format (DSD64, DSD128, DSD256, DSD512), then registers are configured.

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.
