| 2 | |
| 3 | Required properties: |
| 4 | - compatible: "ti,tps65090" |
| 5 | - reg: I2C slave address |
| 6 | - interrupts: the interrupt outputs of the controller |
| 7 | - regulators: A node that houses a sub-node for each regulator within the |
| 8 | device. Each sub-node is identified using the node's name, with valid |
| 9 | values listed below. The content of each sub-node is defined by the |
| 10 | standard binding for regulators; see regulator.txt. |
| 11 | dcdc[1-3], fet[1-7] and ldo[1-2] respectively. |
| 12 | - vsys[1-3]-supply: The input supply for DCDC[1-3] respectively. |
| 13 | - infet[1-7]-supply: The input supply for FET[1-7] respectively. |
| 14 | - vsys-l[1-2]-supply: The input supply for LDO[1-2] respectively. |
| 15 | |
| 16 | Optional properties: |
| 17 | - ti,enable-ext-control: This is applicable for DCDC1, DCDC2 and DCDC3. |
| 18 | If DCDCs are externally controlled then this property should be there. |
| 19 | - "dcdc-ext-control-gpios: This is applicable for DCDC1, DCDC2 and DCDC3. |
| 20 | If DCDCs are externally controlled and if it is from GPIO then GPIO |
| 21 | number should be provided. If it is externally controlled and no GPIO |
| 22 | entry then driver will just configure this rails as external control |
| 23 | and will not provide any enable/disable APIs. |
| 24 | |
| 25 | Each regulator is defined using the standard binding for regulators. |
| 26 | |
