Add support for input supply in DT parsing of node. The input supply will be provided by the property "vin-supply" in the regulator node. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

Fixed Voltage regulators
|
|
|
|
Required properties:
|
|
- compatible: Must be "regulator-fixed";
|
|
|
|
Optional properties:
|
|
- gpio: gpio to use for enable control
|
|
- startup-delay-us: startup time in microseconds
|
|
- enable-active-high: Polarity of GPIO is Active high
|
|
If this property is missing, the default assumed is Active low.
|
|
- gpio-open-drain: GPIO is open drain type.
|
|
If this property is missing then default assumption is false.
|
|
-vin-supply: Input supply name.
|
|
|
|
Any property defined as part of the core regulator
|
|
binding, defined in regulator.txt, can also be used.
|
|
However a fixed voltage regulator is expected to have the
|
|
regulator-min-microvolt and regulator-max-microvolt
|
|
to be the same.
|
|
|
|
Example:
|
|
|
|
abc: fixedregulator@0 {
|
|
compatible = "regulator-fixed";
|
|
regulator-name = "fixed-supply";
|
|
regulator-min-microvolt = <1800000>;
|
|
regulator-max-microvolt = <1800000>;
|
|
gpio = <&gpio1 16 0>;
|
|
startup-delay-us = <70000>;
|
|
enable-active-high;
|
|
regulator-boot-on;
|
|
gpio-open-drain;
|
|
vin-supply = <&parent_reg>;
|
|
};
