associated are in a source file called i2c-designware-common and
are used by both i2c-designware-master and i2c-designware-slave.
- To decrease noise in namespace common i2c_dw_*() functions are
now using ops to keep them private.
- Designware PCI driver had to be changed to match the previous ops
functions implementation.
Almost all of the "core" source is now part of the "master" source. The
difference is the functions used by both modes and they are in the
"common" source file.

I take my ack back. You are adding comment for
dynamic_tar_update_enabled which was removed by the 12688dc21f71
("Revert "i2c: designware: detect when dynamic tar update is possible"")
