Geert Uytterhoeven 3775d589ed pinctrl: renesas: rzv2m: Handle non-unique subnode names 
[ Upstream commit f46a0b47cc ]

The eMMC and SDHI pin control configuration nodes in DT have subnodes
with the same names ("data" and "ctrl").  As the RZ/V2M pin control
driver considers only the names of the subnodes, this leads to
conflicts:

    pinctrl-rzv2m b6250000.pinctrl: pin P8_2 already requested by 85000000.mmc; cannot claim for 85020000.mmc
    pinctrl-rzv2m b6250000.pinctrl: pin-130 (85020000.mmc) status -22
    renesas_sdhi_internal_dmac 85020000.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.

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.
