[PATCH 00/10] pinctrl: mvebu: remove hard-coded addresses from Dove pinctrl

[Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>]

This is a patches separated from one sent earlier [1] with just the
removal of any hard-coded reg addresses from Dove pinctrl stub. This
is a required step for Dove to leave mach-dove, hop into mach-mvebu,
and become part of multi_v7.

In the meantime, support for new Armada 375/38x was added that also
contain patches for pinctrl [2]. The cleanup patches [3] split off from
the original patch set take care of pinctrl-related changes for Armada
375/38x. Since this patch set now already depends on Armada 375/38x
pinctrl through those cleanup patches, we take care of Armada 375/38x
binding updates here, too.

For Dove, this patch set removes all hardcoded addresses from
pinctrl-dove by either requesting additional resources or a syscon
provided regmap for global config registers. As this changes existing
driver to DT binding relationship, all additional resources are probed
in a backward compatible way. If the corresponding resource cannot be
found, we derive it from the existing pinctrl resource and warn about
the old DTB firmware.

Patches 1-2 add or update binding documentation for dove, global config
syscon, and pinctrl-dove. Patch 2 also documents missing reg property
requirement for other mvebu pinctrl nodes, including new Armada 375/38x.

Patch 3 and 4 add the new pinctrl reg property values and global config
register syscon to exisiting dove.dtsi.

Patches 5-6 request either additional reg ranges or the syscon regmap
in a DT-backward compatible way. If any resource cannot be derived from
DT node, we warn about an old DTB firmware.

Patches 7-10 finally remove any hardcoded addresses from Dove SoC
pinctrl driver and use the iomap/regmap resources instead.

DT and binding related patches have also been sent to DT maintainers
and corresponding lists, additional pinctrl related patches have been
sent to pinctrl/mvebu maintainers and LAKML only.

This patch set is based on v3.14-rc1 and depends on some cleanup patches
that will go into v3.15. We have a lot of stuff for v3.15 already in
mvebu, so I am okay with postponing this and/or the following dove-to-
mvebu patches for v3.16. As Jason prepares mvebu pinctrl PRs for LinusW,
it is up to him when to take it with LinusW's Acked-by.

Nevertheless, there is an *unstable* branch based on v3.14-rc1, with
mvebu/pinctrl-3xx and mvebu/pinctrl merged in at (still named -for-3.15)
