Hi
Ok, sorry :-(
But I really do not. I've hacked together a script that will scan all
the code for the function, and test builds with some different config
options turned on.
Kind regards

It's referenced in 64-bit kernels from arch/powerpc/kernel/systbl.S,
via the SYS32ONLY(mmap2) line in arch/powerpc/include/asm/systbl.h.

This patch adds a new documentation file explaining the DSCR
support on powerpc platforms. This explains DSCR related data
structure, code paths and also available user interfaces. Any
further functional changes to the DSCR support in the kernel
should definitely update the documentation here.
The patch exposes the available i2c busses on the PowerNV platform
to the kernel and implements the bus driver to support i2c and
smbus commands.
The driver uses the platform device infrastructure to probe the busses
on the platform and registers them with the i2c driver framework.
