TPS65090 regulators
|
|
|
|
Required properties:
|
|
- compatible: "ti,tps65090"
|
|
- reg: I2C slave address
|
|
- interrupts: the interrupt outputs of the controller
|
|
- regulators: A node that houses a sub-node for each regulator within the
|
|
device. Each sub-node is identified using the node's name, with valid
|
|
values listed below. The content of each sub-node is defined by the
|
|
standard binding for regulators; see regulator.txt.
|
|
dcdc[1-3], fet[1-7] and ldo[1-2] respectively.
|
|
- vsys[1-3]-supply: The input supply for DCDC[1-3] respectively.
|
|
- infet[1-7]-supply: The input supply for FET[1-7] respectively.
|
|
- vsys-l[1-2]-supply: The input supply for LDO[1-2] respectively.
|
|
|
|
Optional properties:
|
|
- ti,enable-ext-control: This is applicable for DCDC1, DCDC2 and DCDC3.
|
|
If DCDCs are externally controlled then this property should be there.
|
|
- "dcdc-ext-control-gpios: This is applicable for DCDC1, DCDC2 and DCDC3.
|
|
If DCDCs are externally controlled and if it is from GPIO then GPIO
|
|
number should be provided. If it is externally controlled and no GPIO
|
|
entry then driver will just configure this rails as external control
|
|
and will not provide any enable/disable APIs.
|
|
|
|
Each regulator is defined using the standard binding for regulators.
|
|
|
|

tps65090@48 {

|

|
|

|
|
infet2-supply = <&some_reg>;
|
|
infet3-supply = <&some_reg>;
|
|
infet4-supply = <&some_reg>;
|
|
infet5-supply = <&some_reg>;
|
|
infet6-supply = <&some_reg>;
|
|
infet7-supply = <&some_reg>;
|
|
vsys_l1-supply = <&some_reg>;
|
