As R-Car H3 ES1.x (R8A77950) and R-Car ES2.0+ (R8A77951) use the same compatible value, the pin control driver relies on soc_device_match() with soc_id = "r8a7795" and the (non)matching of revision = "ES1.*" to match with and distinguish between the two SoC variants. The corresponding entries in the normal of_match_table are present only to make the optional sanity checks work. The R-Car H3e-2G (R8A779M1) SoC is a different grading of the R-Car H3 ES3.0 (R8A77951) SoC. It uses the same compatible values for individual devices, but has an additional compatible value for the root node. When running on an R-Car H3e-2G SoC, soc_device_match() with soc_id = "r8a7795" does not return a match. Hence the pin control driver falls back to the normal of_match_table, and, as the R8A77950 entry is listed first, incorrectly uses the sub-driver for R-Car H3 ES1.x. Fix this by moving the entry for R8A77951 before the entry for R8A77950. Simplify sh_pfc_quirk_match() to only handle R-Car H3 ES1,x, as R-Car H3 ES2.0+ can now be matched using the normal of_match_table as well.

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.
