Subject: [PATCH 0/4] spi: dw: Cleanup macros/funcs naming and add IP-core version support

This patchset consists of the changes which I was going to introduce for a
long time, but due to lack of free time couldn't make it so far.
Nandhini's series [1] made me to proceed with this task so mate would
finally have his patchset accepted and merged into the mainline kernel.

There are three cleanup patches here and one feature patch. In framework
of the former patches we suggest to better organize the code. In
particular they concern the methods and macros naming unification (using a
unified prefixes of the code object names) and CSR fields macro
implementation using the bitfield helpers available in the kernel. The
later patch introduces the Synopsys Component Version register parsing
procedure so the corresponding data could be used for a version-specific
features implementation.  Nandhini will be mostly interested in the later
patch in the framework of his series [1].

Nandhini, could you please test the patchset out on your DWC SSI hardware?
After it's merged into the spi/for-next branch of the Mark' repository you
will be able to rebase your series on top of it and use the last patch
functionality for your benefit.
