-Voltage/Current Regulators
-
-Optional properties:
-- regulator-name: A string used as a descriptive name for regulator outputs
-- regulator-min-microvolt: smallest voltage consumers may set
-- regulator-max-microvolt: largest voltage consumers may set
-- regulator-microvolt-offset: Offset applied to voltages to compensate for voltage drops
-- regulator-min-microamp: smallest current consumers may set
-- regulator-max-microamp: largest current consumers may set
-- regulator-input-current-limit-microamp: maximum input current regulator allows
-- regulator-always-on: boolean, regulator should never be disabled
-- regulator-boot-on: bootloader/firmware enabled regulator
-- regulator-allow-bypass: allow the regulator to go into bypass mode
-- regulator-allow-set-load: allow the regulator performance level to be configured
-- <name>-supply: phandle to the parent supply/regulator node
-- regulator-ramp-delay: ramp delay for regulator(in uV/us)
- For hardware which supports disabling ramp rate, it should be explicitly
- initialised to zero (regulator-ramp-delay = <0>) for disabling ramp delay.
-- regulator-enable-ramp-delay: The time taken, in microseconds, for the supply
- rail to reach the target voltage, plus/minus whatever tolerance the board
- 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-settling-time-us: Settling time, in microseconds, for voltage
- change if regulator have the constant time for any level voltage change.
- This is useful when regulator have exponential voltage change.
-- regulator-settling-time-up-us: Settling time, in microseconds, for voltage
- increase if the regulator needs a constant time to settle after voltage
- increases of any level. This is useful for regulators with exponential
- voltage changes.
-- regulator-settling-time-down-us: Settling time, in microseconds, for voltage
- decrease if the regulator needs a constant time to settle after voltage
- decreases of any level. This is useful for regulators with exponential
- voltage changes.
-- regulator-soft-start: Enable soft start so that voltage ramps slowly
-- 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-min-microvolt: minimum voltage may be set in
- suspend state.
- - regulator-suspend-max-microvolt: maximum voltage may be set in
- suspend state.
- - regulator-suspend-microvolt: the default voltage which regulator
- would be set in suspend. This property is now deprecated, instead
- setting voltage for suspend mode via the API which regulator
- driver provides is recommended.
- - regulator-changeable-in-suspend: whether the default voltage and
- the regulator on/off in suspend can be changed in runtime.
- - 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.
-- regulator-allowed-modes: list of operating modes that software is allowed to
- configure for the regulator at run-time. Elements may be specified in any
- order. The set of possible operating modes depends on the capabilities of
- every hardware so each device binding document explains which values the
- regulator supports.
-- regulator-system-load: Load in uA present on regulator that is not captured by
- any consumer request.
-- regulator-pull-down: Enable pull down resistor when the regulator is disabled.
-- regulator-over-current-protection: Enable over current protection.
-- regulator-active-discharge: tristate, enable/disable active discharge of
- regulators. The values are:
- 0: Disable active discharge.
- 1: Enable active discharge.
- Absence of this property will leave configuration to default.
-- regulator-coupled-with: Regulators with which the regulator
- is coupled. The linkage is 2-way - all coupled regulators should be linked
- with each other. A regulator should not be coupled with its supplier.
-- regulator-coupled-max-spread: Max spread between voltages of coupled regulators
- in microvolts.
-
-Deprecated properties:
-- regulator-compatible: If a regulator chip contains multiple
- regulators, and if the chip's binding contains a child node that
- describes each regulator, then this property indicates which regulator
- this child node is intended to configure. If this property is missing,
- the node's name will be used instead.
-
-Example:
-
- xyzreg: regulator@0 {
- regulator-min-microvolt = <1000000>;
- regulator-max-microvolt = <2500000>;
- regulator-always-on;
- vin-supply = <&vin>;
-
- regulator-state-mem {
- regulator-on-in-suspend;
- };
- };
-
-Regulator Consumers:
-Consumer nodes can reference one or more of its supplies/
-regulators using the below bindings.
-
-- <name>-supply: phandle to the regulator node
-
-These are the same bindings that a regulator in the above
-example used to reference its own supply, in which case
-its just seen as a special case of a regulator being a
-consumer itself.
-
-Example of a consumer device node (mmc) referencing two
-regulators (twl_reg1 and twl_reg2),
-
- twl_reg1: regulator@0 {
- ...
- ...
- ...
- };
-
- twl_reg2: regulator@1 {
- ...
- ...
- ...
- };
-
- mmc: mmc@0 {
- ...
- ...
- vmmc-supply = <&twl_reg1>;
- vmmcaux-supply = <&twl_reg2>;
- };
