Paul Mundt 61a6976bf1 serial: sh-sci: Abstract register maps.
This takes a bit of a sledgehammer to the horribly CPU subtype
ifdef-ridden header and abstracts all of the different register layouts
in to distinct types which in turn can be overriden on a per-port basis,
or permitted to default to the map matching the port type at probe time.

In the process this ultimately fixes up inumerable bugs with mismatches
on various CPU types (particularly the legacy ones that were obviously
broken years ago and no one noticed) and provides a more tightly coupled
and consolidated platform for extending and implementing generic
features.

Paul Mundt c7ed1ab3f7 serial: sh-sci: clkdev updates for MSTP gating.
This fixes up some of the I/D/F clock ambiguity in the sh-sci driver.
The interface clock in most cases just wraps back to the peripheral
clock, while the function clock wraps in to the MSTP bits. As the logic
was somewhat inverted, this cleans that up, and also enables all CPUs
with SCI MSTP bits to match function clocks through clkdev lookup.

As a result, this gets rid of the clk string abuse on the sh side, and
the clock string will be killed off once the ARM code has had a chance to
sync up. This also enables MSTP gating on CPUs like 7786 which had never
wired it up before. Impacted CPUs are primarily all SH-Mobiles, SH7785,
and SH7786.

The shdma dmaengine driver currently uses numerous macros to support various

lists of channel descriptors to specify register locations, interrupt numbers
and other system-specific configuration variants. Unavoidably, we have to
simultaneously convert all shdma users to provide those resources.

Convert the processor platform device setup
functions from __initcall() and sometimes

This makes sure that the platform devices are

A good example is platform devices needed by

Convert the m66592-udc driver to use the on_chip flag
from platform data to enable on chip behaviour instead
of relying on CONFIG_SUPERH_BUILT_IN_M66592 ugliness.

This makes the code cleaner and also allows us to support
both external and internal m66592 with the same kernel.

It also makes the Kconfig part more future proof since
we with this patch can add support for new processors
with on-chip m66592 without modifying the Kconfig.

The patch adds a m66592 header file for platform data
and ties in platform data to the existing m66592 devices.
