Currently, sd1 and sd0 have unique subnode names 'sd1_mux' and 'sd0_mux'.
If we change these to non-unique subnode names such as 'mux' this can
lead to the below conflict as the RZ/G2L pin control driver considers
only the names of the subnodes.
pinctrl-rzg2l 11030000.pinctrl: pin P47_0 already requested by 11c00000.mmc; cannot claim for 11c10000.mmc
pinctrl-rzg2l 11030000.pinctrl: pin-376 (11c10000.mmc) status -22
pinctrl-rzg2l 11030000.pinctrl: could not request pin 376 (P47_0) from group mux on device pinctrl-rzg2l
renesas_sdhi_internal_dmac 11c10000.mmc: Error applying setting, reverse things back
Fix this by constructing unique names from the node names of both the
pin control configuration node and its child node, where appropriate.
Based on the work done by Geert for the RZ/V2M pinctrl driver.

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.
