Hi,


Changes since v5
================
1. Remove patch 1 and 2 - applied.
2. Patch 1/3: remove suspend_enable functions (suggested by Mark Brown).
3. Patch 1/3: Add Javier's reviewed-by.
4. Add patch 2/3: remove suspend_enable for max77802 also.

Changes since v4
================
1. New patch: 2/4. Store the current value of opmode in
   non-shifted form. Along with changes in defines used for opmodes
   this simplifies everything a lot. Suggested by Javier.
2. Drop Javier's review-by from patch 1 because I changed the
   defines to cover both LDO and buck at the same time.
3. Patch 3/4: adding suspend disable is now simpler - just re-use
   the existing function.

Changes since v3
================
1. Dropped patch 3/4 ("mfd/regulator: dt-bindings: max77686: Document
   regulators off in suspend"), applied by Lee Jones.
2. Patch 2/3: Fix missing shift when checking if current opmode is
   equal to off in suspend. The shift is various so I added a simple
   function max77686_set_opmode_enable(). Dropped Javier's review-by.
3. Patch 1/3: Add Javier's review-by.
4. Patch 3/3: Add Chanwoo's review-by.

Changes since v2
================
1. Patch 1/4: Fully describe different values used for controlling
   the regulators (low power modes, enable, disable). Remove "opmode"
   from new defines. Suggested by Javier.
2. Patch 2/4: minor nits after changing patch 1.
3. Add Javier's reviewed-by to 2, 3 and 4 patch.
4. Patch 3/4 (changes in documentation) should be picked up by Lee
   Jones but I'm resending it anyway.

Changes since v1
================
1. Add patch 1/4 and 3/4.
2. Patch 2/4: Extend existing set_suspend_disable (for bucks) with
   LDO support. Implement set_suspend_enable. Suggested by Javier.
3. Patch 4/4: Add regulator suspend properties only to regulators
   actually supporting this. Other regulators, not implementing
   suspend enable/disable, will warn ("VCC_1.8V_IO: No configuration").
4. Patch 4/4: In suspend enable VHSIC_1.0V and VHSIC_1.8V regulators.
   Suggested by Chanwoo Choi.


Description
===========
This patchset makes use of Javier Martinez Cainllas changes [1].
It allows disabling some of the regulators during suspend to RAM.

Javier's patchset is necessary only to test it.

Some LDOs of Maxim 77686 PMIC support disabling during system suspend
(LDO{2,6,7,8,10,11,12,14,15,16}). This was already implemented as part
of set_suspend_mode function. In that case the mode was one of:
 - disable,
 - normal mode,
 - low power mode.
However there are no bindings for setting the mode during suspend.

Add suspend disable for LDO regulators supporting this. Re-use existing
max77686_buck_set_suspend_disable() function. This helps reducing
energy consumption during system sleep.

The Maxim 77802 PMIC regulators do not have special enable configuration
for suspend. The driver instead enabled them manually which is not a
best way to deal with suspend.

Add suspend to RAM configuration for max77686 regulators. Some LDOs and
bucks are disabled. This reduces energy consumption during S2R,
approximately from 17 mA to 9 mA.

Additionally remove old and not supported bindings:
 - regulator-mem-off
 - regulator-mem-idle
 - regulator-mem-on
The max77686 driver does not parse them and they are not documented
anywere.
