[ Upstream commit cc2d819dd7df94a72bde7b9b9331a6535084092d ]
We are using a wrong mcbsp functional clock. The interconnect target module
driver provided clock for mcbsp is not same as the mcbsp functional clock
known as the gfclk main_clk. The mcbsp functional clocks for mcbsp should
have been added before we dropped the legacy platform data.
Additionally we are also missing the clock aliases for the clocks used by
the audio driver if reparenting is needed. This causes audio driver errors
like "CLKS: could not clk_get() prcm_fck" for mcbsp as reported by Andreas.
The mcbsp clock aliases too should have been added before we dropped the
legacy platform data.
Let's add the clocks and aliases with a single patch to fix the issue.

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.
