Originally the device tree binding only specified one clock reference, with the name "extclk". The driver simply retrieves the clock without bothering to specify a name. Since we added a second clock to the binding, we need to fetch the clocks by name now. First we try the new name "txco", then fall back to the old name "extclk", and finally try retrieving a clock without using any name, to cover any instances where a bad device tree or firmware worked by accident. In the last case, we should take care that we don't get the same clock twice when we add support for the "lpo" clock.

README
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.
