1 | Device-Tree bindings for regulators of Active-semi ACT8945A Multi-Function Device |
| 2 | ||
| 3 | Required properties: | |
| 4 | - compatible: "active-semi,act8945a", please refer to ../mfd/act8945a.txt. | |
| 5 | ||
| 6 | Optional properties: | |
| 7 | - active-semi,vsel-high: Indicates if the VSEL pin is set to logic-high. | |
| 8 | If this property is missing, assume the VSEL pin is set to logic-low. | |
| 9 | ||
| 10 | Optional input supply properties: | |
| 11 | - vp1-supply: The input supply for REG_DCDC1 | |
| 12 | - vp2-supply: The input supply for REG_DCDC2 | |
| 13 | - vp3-supply: The input supply for REG_DCDC3 | |
| 14 | - inl45-supply: The input supply for REG_LDO1 and REG_LDO2 | |
| 15 | - inl67-supply: The input supply for REG_LDO3 and REG_LDO4 | |
| 16 | ||
| 17 | Any standard regulator properties can be used to configure the single regulator. | |
| 18 | ||
| 19 | The valid names for regulators are: | |
| 20 | REG_DCDC1, REG_DCDC2, REG_DCDC3, REG_LDO1, REG_LDO2, REG_LDO3, REG_LDO4. | |
| 21 | ||
| 22 | Example: | |
| 23 | pmic@5b { | |
| 24 | compatible = "active-semi,act8945a"; | |
| 25 | reg = <0x5b>; | |
| 26 | status = "okay"; | |
| 27 | ||
| 28 | active-semi,vsel-high; | |
