TPS65132 regulators
|
|
|
|
Required properties:
|
|
- compatible: "ti,tps65132"
|
|
- reg: I2C slave address
|
|
|
|
Optional Subnode:
|
|
Device supports two regulators OUTP and OUTN. A sub node within the
|
|
device node describe the properties of these regulators. The sub-node
|
|
names must be as follows:
|
|
-For regulator outp, the sub node name should be "outp".
|
|
-For regulator outn, the sub node name should be "outn".
|
|
|
|
-enable-gpios:(active high, output) Regulators are controlled by the input pins.
|
|
If it is connected to GPIO through host system then provide the
|
|
gpio number as per gpio.txt.
|
|
-active-discharge-gpios: (active high, output) Some configurations use delay mechanisms
|
|
on the enable pin, to keep the regulator enabled for some time after
|
|
the enable signal goes low. This GPIO is used to actively discharge
|
|
the delay mechanism. Requires specification of ti,active-discharge-time-us
|
|
-ti,active-discharge-time-us: how long the active discharge gpio should be
|
|
asserted for during active discharge, in microseconds.
|
|
|
|
Each regulator is defined using the standard binding for regulators.
|
|
|
|
Example:
|
|
|
|
tps65132@3e {
|
|
compatible = "ti,tps65132";
|
|
reg = <0x3e>;
|
|
|
|
outp {
|
|
regulator-name = "outp";
|
|
regulator-boot-on;
|
|
regulator-always-on;
|
|
enable-gpios = <&gpio 23 0>;
|
|
};
|
|
|
|
outn {
|
|
regulator-name = "outn";
|
|
regulator-boot-on;
|
|
regulator-always-on;
|
|
regulator-active-discharge = <0>;
|
|
enable-gpios = <&gpio 40 0>;
|
|
};
|
|
};
