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-always-on: boolean, regulator should never be disabled
|
||
|
|
- regulator-boot-on: bootloader/firmware enabled regulator
|
||
|
|
- <name>-supply: phandle to the parent supply/regulator node
|
||
|
|
- qcom,consumer-supplies: flattened list of supply and dev_name pairs
|
||
|
|
This property is used to support regulator consumers that have no device
|
||
|
|
tree node. An empty string, "", can be used to specify a null device
|
||
|
|
name. A null device name is used to allow calls such as:
|
||
|
|
regulator_get(NULL, "pll_vdd").
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
xyzreg: regulator@0 {
|
||
|
|
regulator-min-microvolt = <1000000>;
|
||
|
|
regulator-max-microvolt = <2500000>;
|
||
|
|
regulator-always-on;
|
||
|
|
vin-supply = <&vin>;
|
||
|
|
qcom,consumer-supplies = "pll_vdd", "", "lcd_vcc", "foo.1";
|
||
|
|
};
|
||
|
|
|
||
|
|
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@0x0 {
|
||
|
|
...
|
||
|
|
...
|
||
|
|
vmmc-supply = <&twl_reg1>;
|
||
|
|
vmmcaux-supply = <&twl_reg2>;
|
||
|
|
};
