Good catch!
I've removed these three now and and will add the removal to
the same patch, also the related
samsung,s3c2412-clock.txt and samsung,s3c2443-clock.txt
files.

samsung,s3c2412-nand is apparently still used on s3c6400,
and the driver is selectable on that platform, so I think
that should remain in there until we remove s3c64xx in 2024,
even if it is not referenced by the dts files in the kernel.

Similarly, the driver is used on the crag6410 board
(without DT), and probably just works with the DT based
boards if one adds a node to s3c64xx.dtsi.
I've also checked if any of the other removed drivers
matches of_device_id[] strings to see if there are more
bindings to kill off, but I don't see any that have
now become obsolete. It did point me to pxa2xx_ac97_dt_ids,
which Robert already complained about, this apparently
is still used with dts files outside of mainline.
