description: >
The power management module inside the TWL4030 provides several
facilities to control the power resources, including power scripts.
For now, the binding only supports the complete shutdown of the
system after poweroff.
Board-specific compatible strings may be used for platform-specific
power configurations.
A board-specific compatible string (e.g., ti,twl4030-power-omap3-evm)
may be paired with a generic fallback (generally for power saving mode).
