[ Upstream commit bf51d3b2d048c312764a55d91d67a85ee5535e31 ]
The onitial value of the CPG_PL2SDHI_DSEL bits 0..1 or 4..6 is 01b. The
hardware user's manual (r01uh0914ej0130-rzg2l-rzg2lc.pdf) specifies that
setting 0 is prohibited. Hence rzg2l_cpg_sd_clk_mux_get_parent() should
just read CPG_PL2SDHI_DSEL, trust the value, and return the proper clock
parent index based on the value read.

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.
