Subject: [PATCH v3 0/4] regulator: max77686/trats2: Disable some regulators in
 suspend

Hi,

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.
