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.
For example:
ldoX_reg: LDOx { regulator-name = "VAP_XXX_1.2V"; regulator-min-microvolt = <1200000>; regulator-max-microvolt = <1200000>; regulator-always-on;
regulator-initial-state = <3>; /* PM_SUSPEND_MEM */ regulator-state-standby { regulator-volt = <1200000>; regulator-mode = <0x2>; /* REGULATOR_MODE_NORMAL */ };
regulator-state-mem { regulator-volt = <1200000>; regulator-mode = <0x8>; /* REGULATOR_MODE_STANDBY */ regulator-off-in-suspend; };
regulator-state-disk { regulator-volt = <1200000>; regulator-mode = <0x2>; /* REGULATOR_MODE_NORMAL */ regulator-on-in-suspend; }; };
