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-state-mem {
regulator-volt = <1200000>;
regulator-off-in-suspend;
};
regulator-state-disk {
regulator-volt = <1200000>;
regulator-on-in-suspend;
};
};
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
