[PATCH 0/3] ARM: vt8500: Add runtime SoC version identification

[Alexey Charkov <alchark@gmail.com>]

VIA/WonderMedia SoCs have a chip ID register, which is helpful for
selecting support for correct sets of hardware quirks at runtime, add
code for it.

This will enable the use of SOC bus match tables in individual drivers,
allowing for finer grained feature selection where device trees might
not provide full information about what the hardware expects (such as
with non-user-visible SoC revisions having different behavior within
the same user-visible SoC version).

This series intentionally omits the updates to MAINTAINERS, as there
are multiple VT8500 related submissions this cycle which may go via
different trees (and cause pain in sequencing the merges). It will be
updated separately in a single pass to cover everything VT8500 related.
