Hi,
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.
