Hi All,

Intro
=====
This patchset converts all devicetree bindings of Samsung S2M and S5M
PMIC devices from txt to dtschema.

It includes also two fixes which are included here at beginning because
later conversion depends on it (contextually).

Merging/dependencies
====================
1. Regulator related binding changes depend on first two commits (the
   fixes), because of context.
2. The mfd bindings depend on clock and regulator bindings.
3. The DTS changes (patches 11 and 12) are independent (including here
   only to provide some context) and I will take them via samsung-soc.

Therefore the fixes and bindings changes (patches 1-10) should go via
the same tree.  For example regulator or mfd tree.  I propose the
regulator tree, since it will have also one driver change (the fix,
first commit).

Overview of devices
===================
Essentially all Samsung S2M and S5M PMICs are very similar devices. They
provide the same functionality: regulators, RTC, 2 or 3 clocks and main
power management (e.g. power cut to SoC).

The differences are mostly in registry layout and number of regulators.

The drivers are built around one common part, mfd/sec-core.c, and share
some drivers between devices:
1. MFD sec-core for all devices,
1. one clock driver for most of devices,
2. one RTC driver for all devices,
3. three regulator drivers.

The regulator drivers were implementing slightly different features,
therefore one regulator binding for all devices does not make much
sense.  However the clock device binding can be shared.

The final dtschema bindings try to implement this - share only the clock
bindings.

Best regards,
Krzysztof
