Stephen Boyd 9611b3aacc clk: mux: Add support for specifying parents via DT/pointers 
After commit fc0c209c14 ("clk: Allow parents to be specified without
string names") we can use DT or direct clk_hw pointers to specify
parents. Create a generic function that shouldn't be used very often to
encode the multitude of ways of registering a mux clk with different
parent information. Then add a bunch of wrapper macros that only pass
down what needs to be passed down to the generic function to support
this with less arguments.

Note: the msm drm driver passes an anonymous array through the macro
which seems to confuse my compiler. Adding a parenthesis around the
whole thing at the call site seems to fix it but it must be wrong. Maybe
it's better to split this patch and pick out the array bits there?

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.
