i.e. will queue in renesas-devel for v6.13.

The driver has been using 32-bit accesses since basically forever.
If we ever need smaller accesses, that can be handled through the
compatible value.  Note that on SH, this driver is used only on SH7757
and SH7724. At least the latter is documented to use 32-bit accesses,
but e.g. SH7785 supports only 8 or 16-bit addresses (depending on
the register).

when I'm talking to journalists I just say "programmer" or something like that.
