Hello Mark,
This series configures the max77802 regulators mode when entering in the
Suspend-to-RAM state. The patches in this series were part of a previous
patch-set that also added initial and suspend mode support for the core.
The previous patch-set was [0] but the feedback was that instead mixing
core changes, bugfixes and new driver features, the series should be split
and core changes posted separately from driver new features.
So this series build on top of the series:
"[PATCH v6 0/5] regulator: of: Add initial and suspend modes support" [1]
and to avoid merge conflicts also depends on Krzysztof's series:
"[PATCH v2 0/3] regulator: max77686/802: Cleanup" [2].
The patch-set is composed of the following patches:
Javier Martinez Canillas (3):
regulator: max77802: Document binding for regulator operating modes
regulator: max77802: Fill regulator modes translation callback
ARM: dts: Configure regulators for suspend on exynos Peach boards

Patch #1 documents the operating modes that are supported by the regulators
in the Maxim 77802 PMIC.
Patch #2 fills the .of_map_mode callback function that is used to translate
between the device specific modes configured in the Device Tree and the
standard modes used by the regulator core.
Patch #3 configures the regulators in the Exynos Peach boards which use a
max77802 PMIC. This patch should be merged through the linux-samsung tree
but I added to the series since shows how the DT binding is used in a DTS.
Best regards,
Javier

Some regulators from the max77802 PMIC support to be configured in one
of two operating mode: Output ON (normal) and Output On Low Power Mode.
Not all regulators support these two modes and for some of them, the
mode can be changed while the system is running in normal operation
while others only support their mode to be changed on system suspend.
Extend the max77802 PMIC binding by documenting the possible operating
modes values so the regulators modes can be configured correctly.

+The max77802 regulator supports two different operating modes: Normal and Low

+The possible values for "regulator-initial-mode" and "regulator-mode" are:

The max77802 PMIC regulators output can be configured in one of two
modes: Output ON (normal) and Output ON in Low Power Mode. Some of
the regulators support their operating mode to be changed on startup
or by consumers when the system is running while others only support
their operating mode to be changed while the system has entered in a
suspend state.
Use the max77802_map_mode() function to translate the device specific
modes to the standard operating modes as used by the regulator core.

The regulator core now has support to choose if a regulator
has to be enabled or disabled during system suspend and also
supports changing the regulator operating mode during runtime
and when the system enters into sleep mode.
To lower power during suspend, configure the regulators state
using the same configuration found in the ChromeOS 3.8 kernel.
