.set_sysclk() is effectively unused here. No machine drivers use jz4740-i2s; and JZ4740_I2S_CLKSRC_EXT is the only selectable clock source with simple-card, but that is also the default source and has a fixed frequency, so configuring it would be redundant. simple-card ignores -ENOTSUPP error codes when setting the sysclock, so any device trees that do set the sysclock for some reason should still work. It's still possible to configure the clock parent manually in the device tree and control frequency using other simple-card options, so at the end of the day there's no real loss in functionality.

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.
