This patch series is a continuation to add support for the VSC7512:
https://patchwork.kernel.org/project/netdevbpf/list/?series=674168&state=*

That series added the framework and initial functionality for the
VSC7512 chip. Several of these patches grew during the initial
development of the framework, which is why v1 will include changelogs.
It was during v9 of that original MFD patch set that these were dropped.

With that out of the way, the VSC7512 is mainly a subset of the VSC7514
chip. The 7512 lacks an internal MIPS processor, but otherwise many of
the register definitions are identical. That is why several of these
patches are simply to expose common resources from
drivers/net/ethernet/mscc/*.

This patch only adds support for the first four ports (swp0-swp3). The
remaining ports require more significant changes to the felix driver,
and will be handled in the future.

v3
* Fix allmodconfig build (patch 8)
* Change documentation wording (patch 12)
* Import module namespace (patch 13)
* Fix array initializer (patch 13)

v2
* Utilize common ocelot_reset routine (new patch 5, modified patch 13)
* Change init_regmap() routine to be string-based (new patch 8)
* Split patches where necessary (patches 9 and 14)
* Add documentation (patch 12) and MAINTAINERS (patch 13)
* Upgrade to PATCH status

v1 (from RFC v8 suggested above):
* Utilize the MFD framework for creating regmaps, as well as
dev_get_regmap() (patches 7 and 8 of this series)
