Up till now there was no single generic method to bind devices to their
power domains using Device Tree. Each platform has been doing this using
its own way, example of which are Exynos power domain bindings [1] and
look-up code [2].

This series is intended to change this and provide generic DT bindings for
power domain specification and generic code performing look-up of power
domains and binding them to devices.

Patches 1, 2, 3 are not directly related to this series, but they are
dependencies of further patches making mach-s3c64xx a user of introduced
code. Patch 4 is the most important part of this series, as it's the one
introducing $subject. Further patches are fixing and adding two users,
mach-exynos (removing the legacy code) and mach-s3c64xx (no DT support for
power domains before). Last two patches are adding display support for
Mini6410 board, including a node for display controller (FIMD) which is
a power domain consumer.

Successfully tested on S3C6410-based Mini6410 board.

I left the references for the end of this cover letter and finally forgot
about them. Please accept my apologies ;).

[1] Documentation/devicetree/bindings/arm/exynos/power_domain.txt
[2] arch/arm/mach-exynos/pm_domains.c

Also it might be good to mention that I was heavily inspired by
implementation of clock providers in Common Clock Framework in case of
provider registration and look-up and also by my Exynos power domain
implementation (now removed by this series ;)) in case of code binding
devices to power domains.
