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. |
|
- ti,overcurrent-wait: This is applicable to FET registers, which have a |
|
poorly defined "overcurrent wait" field. If this property is present it |
|
should be between 0 - 3. If this property isn't present we won't touch the |
|
"overcurrent wait" field and we'll leave it to the BIOS/EC to deal with. |
|
|
|
Each regulator is defined using the standard binding for regulators. |
|
|
|
Example: |
|
|
|
tps65090@48 { |
|
compatible = "ti,tps65090"; |
|
reg = <0x48>; |
|
interrupts = <0 88 0x4>; |
|
|
|
vsys1-supply = <&some_reg>; |
|
vsys2-supply = <&some_reg>; |
|
vsys3-supply = <&some_reg>; |
|
infet1-supply = <&some_reg>; |
|
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>; |
|
vsys-l2-supply = <&some_reg>; |
