| |
Some regulators can run on different operating modes (opmodes). This allows systems to choose the most efficient opmode for each regulator.
This patch builds on top of (291d761 regulator: Document binding for regulator suspend state for PM state) adding a regulator-initial-mode DT property to configure at startup the operating mode for regulators that support changing its mode during normal operation and a property regulator-mode to be used in the regulator-state-[mem/disk] nodes for regulators that supports changing its operating mode when the system enters in a suspend state.
The set of possible modes that a regulator can operate depends on the hardware capabilities so a list of generic operating modes can't be provided. Instead, each hardware binding should define the list of valid operating modes for the regulators found on that device.

Changes in v6: - Remove assumptions about implementation details and don't overspecify. Suggested by Mark Brown.
Changes in v5: None
Changes in v4: None
Changes in v3: - Rebased on top of regulator suspend voltage series
