-GPIO controlled regulators

-Required properties:

- here.
-- gpios : Array of one or more GPIO pins used to select the
- regulator voltage/current listed in "states".
-- states : Selection of available voltages/currents provided by
- this regulator and matching GPIO configurations to
- achieve them. If there are no states in the "states"
- array, use a fixed regulator instead.
-
-Optional properties:
-- enable-gpios : GPIO used to enable/disable the regulator.
- Warning, the GPIO phandle flags are ignored and the
- GPIO polarity is controlled solely by the presence
- of "enable-active-high" DT property. This is due to
- compatibility with old DTs.
-- enable-active-high : Polarity of "enable-gpio" GPIO is active HIGH.
- Default is active LOW.
-- gpios-states : On operating systems, that don't support reading back
- gpio values in output mode (most notably linux), this
- array provides the state of GPIO pins set when
- requesting them from the gpio controller. Systems,
- that are capable of preserving state when requesting
- the lines, are free to ignore this property.
- 0: LOW, 1: HIGH. Default is LOW if nothing else
- is specified.
-- startup-delay-us : Startup time in microseconds.
-- regulator-type : Specifies what is being regulated, must be either
- "voltage" or "current", defaults to voltage.
-
-Any property defined as part of the core regulator binding defined in

-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-standby sub-root node for Standby mode
- : equivalent with standby Linux sleep state, which provides energy savings
- with a relatively quick transition back time.
-- 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/standby] 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: Array of maximum spread between voltages of
- coupled regulators in microvolts, each value in the array relates to the
- corresponding couple specified by the regulator-coupled-with property.
-- regulator-max-step-microvolt: Maximum difference between current and target
- voltages that can be changed safely in a single step.
-
-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>;

+* Dialog Semiconductor SLG51000 Voltage Regulator
+
+Required properties:
+- compatible : Should be "dlg,slg51000" for SLG51000
+- reg : Specifies the I2C slave address.
+- xxx-supply: Input voltage supply regulator for ldo3 to ldo7.
+ These entries are required if regulators are enabled for a device.
+ An absence of these properties can cause the regulator registration to fail.
+ If some of input supply is powered through battery or always-on supply then
+ also it is required to have these parameters with proper node handle of always
+ on power supply.
+ vin3-supply: Input supply for ldo3
+ vin4-supply: Input supply for ldo4
+ vin5-supply: Input supply for ldo5
+ vin6-supply: Input supply for ldo6
+ vin7-supply: Input supply for ldo7
+
+Optional properties:
+- interrupt-parent : Specifies the reference to the interrupt controller.
+- interrupts : IRQ line information.
+- dlg,cs-gpios : Specify a valid GPIO for chip select
+
+Sub-nodes:
+- regulators : This node defines the settings for the regulators.
+ The content of the sub-node is defined by the standard binding
+ for regulators; see regulator.txt.
+
+ The SLG51000 regulators are bound using their names listed below:
+ ldo1
+ ldo2
+ ldo3
+ ldo4
+ ldo5
+ ldo6
+ ldo7
+
+Optional properties for regulators:
+- enable-gpios : Specify a valid GPIO for platform control of the regulator.
+
+Example:
+ pmic: slg51000@75 {
+ compatible = "dlg,slg51000";
+ reg = <0x75>;
+
+ regulators {
+ ldo1 {
