Subject: [PATCH v4 00/10] regulator/mfd/clock: dt-bindings: Samsung S2M and S5M to dtschema

Hi All,

Changes since v2
================
1. Add Stephen's and Rob's tags.
2. Correct inb-supply description in patch 10/10.

Changes since v2
================
1. Add Rob's tags.
2. Remove "regulator-name" from properties (all regulator dtschema).
3. Move "unevaluatedProperties" higher to make code easier to read (all regulator dtschema).
4. Add ref-type to op-mode property (patch 6: s5m8767 regulators).

Changes since v1
================
1. Drop DTS patches - applied.
2. Fully remove bindings/regulator/samsung,s5m8767.txt .
3. Minor subject reformatting and few typos in text.


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

It includes also two fixes 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.

The fixes and bindings changes (patches 1-10) should go via the same
tree.  For example regulator or mfd tree.

Another alternative is that regulator patches (1-2, 4-6) go via Mark who
later gives MFD a stable branch/tag to pull. Then the clock and MFD
bindings would go on top via MFD tree. Or any other setup you would like
to have.


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 registers 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
