The regulators would set different state/mode according to the kind of suspend state. So regulation_constraints structure has already regulator suspend state filed. This patch parse regulator suspend state from devicetree file.
I tested this patch on Rinato board (Samsung Gear 2) included S2MPS14 PMIC. - The power-consumption in suspend state is 0.6mA after applied this patchset.
For example: ldoX_reg: LDOx { regulator-name = "VAP_XXX_1.2V"; regulator-min-microvolt = <1200000>; regulator-max-microvolt = <1200000>; regulator-always-on;
regulator-state-mem { regulator-off-in-suspend; }; };
Changes from v4: - Rebase this patchset on for-next branch of regulator.git - Remove 'regulator-volt' property - Remove 'regulator-initial-state' property - Add example patch[1, patch3] based on Rinato board[2] included S2MPS14 PMIC. S2MPS14 PMIC patch[3] has already implemented '.set_suspend_disable()' func to change the regulator state to reduce power-consumption in suspend-state.

[3] regulator: s2mps11: Add set_suspend_disable for S2MPS14 (commid id: 05be09bb5ec8d12051515087a1983745dc93d906)
Changes from v3: - Don't support 'regulator-state-standby' mode - Remove 'regulator-mode' property
Changes from v2: - Fix over 80 lines by using checkpatch script - Rebase this patchset on latest for-next branch of regulator.git
Changes from v1: - Check whether regulator-initial-state and regulator-mode is correct or not - Add more detailed description about regulator-initial-state, regulator-mode and regulator-state-[standby/mem/disk] for devicetree bindings - Modify example of regulator suspend state in bindings documentation
