I wonder if this will make the compatibility with old
platforms (like SH4) not based on DT, where there was not used
any glue-logic around the driver and just the platform was the
To be honest, I prefer to not have the Kconfig options.
The device-tree compatibility will select the glue-logic
needed and we will just pay some bytes when compile.
In my opinion, the Koption(s) introduce a problem when touch
the driver and we want to guarantee that, at least,
all its parts build fine on all the platforms.
