[PATCH v2 0/4] add coupled regulators for Exynos5422/5800

Hi,

The main purpose of this patch series is to add coupled regulators for
Exynos5422/5800 to keep constrain on voltage difference between vdd_arm
and vdd_int to be at most 300mV. In exynos-bus instead of using
regulator_set_voltage_tol() with default voltage tolerance it should be
used regulator_set_voltage_triplet() with volatege range, and this is
already present in opp/core.c code, so it can be reused. While at this,
move setting regulators into opp/core.

This patchset was tested on Odroid XU3.

The last patch depends on two previous.

Changes in v2:

- improve regulators enable/disable code in opp/core as suggested by
Viresh Kumar
- add new patch for remove unused dt-bindings as suggested by Krzysztof
Kozlowski

Regards,
Kamil
