design requires. This property describes the total system ramp time
required due to the combination of internal ramping of the regulator itself,
and board design issues such as trace capacitance and load on the supply.
- regulator-state-mem sub-root node for Suspend-to-RAM mode
: suspend to memory, the device goes to sleep, but all data stored in memory,
only some external interrupt can wake the device.
- regulator-state-disk sub-root node for Suspend-to-DISK mode
: suspend to disk, this state operates similarly to Suspend-to-RAM,
but includes a final step of writing memory contents to disk.
- regulator-state-[mem/disk] node has following common properties:
- regulator-on-in-suspend: regulator should be on in suspend state.
- regulator-off-in-suspend: regulator should be off in suspend state.
- regulator-suspend-microvolt: regulator should be set to this voltage
in suspend.
- regulator-mode: operating mode in the given suspend state.
The set of possible operating modes depends on the capabilities of
every hardware so the valid modes are documented on each regulator
device tree binding document.
- regulator-initial-mode: initial operating mode. The set of possible operating
modes depends on the capabilities of every hardware so each device binding
documentation explains which values the regulator supports.
